as reported by pilots. Diffuse steam plumes from fumarolic vents in Main Crater rose only 5 m. Sulfur dioxide emissions were 1,327 tonnes per day on 10 March, and fluctuated between 518 and 795 tonnes per day through 14 March. Prior to 2020 the most recent eruption was in 1977, on the south flank near Mt. "Recorded earthquakes began increasing 30 October. Small but continuing local vibrations recorded by Volcano Island seismograph. Expand each entry for additional details. The ejecta reached a height of 1,000 feet above the crater, which was widened to 20 m in diameter. Synonyms of features appear indented below the primary name. According to the Disaster Response Operations Monitoring and Information Center (DROMIC) there were a total of 53,832 people dispersed to 244 evacuation centers by 1800 on 15 January. Most activity was from a 100-m-diameter vent within the 1965-70 cone, on which scattered impact craters a few centimeters to 0.7 m across were present up to 500 m from the vent. In this path breaking, transnational study, Paul A. Kramer reveals how racial politics served U.S. empire, and how empire-building in turn transformed ideas of race and nation in both the United States and the Philippines. According to the Disaster Response Operations Monitoring and Information Center (DROMIC) there were a total of 125,178 people in 497 evacuation centers as of 2020 on 28 January. What is the current state of the Taal volcano? Strong, frequent eruptions with ashfall through mid-October. Rosa, Laguna. Tabaro eruption site, Taal volcano: Philippines, Philippine Journal of Volcanology, v. 1, no. By the following day, >2,600 of the island's 6,000 residents had reportedly been evacuated. IAVCEI Data Sheets, Rome: Internatl Assoc Volc Chemistry Earth's Interior. It is about 31 miles south of the Philippine capital of Manila. Felt earthquakes (Intensities II-V) continued to be recorded in local areas. Tambaro. Ejection of voluminous ash-laden steam clouds on 9 November. Harmonic tremor amplitude was unchanged. PHIVOLCS stated that by 21 January hybrid earthquakes had ceased and both the number and magnitude of low-frequency events had diminished. Weak phreatic eruption with harmonic tremor. Its unexplained shape and location on an island within a lake within an island, makes it a unique geologic wonder, enthralling thousands of tourists and geologists yearly. Taal Lake lies within a 2530km (1619mi) caldera formed by explosive eruptions between 140,000 and 5,380 BP. One hybrid event was detected during 28-29 April. COMVOL visual observation during afternoon showed appreciable increase in amount ash and fragmental red hot volcanic materials and considerable enlargement in diameter of active vent. | July During 19-21 May there were 2-30 daily low-frequency events, 10-169 daily volcanic earthquakes, and 8-139 periods of volcanic tremor with variable durations (1-37 minutes); no earthquakes were recorded during 22-25 May. Ground-probe hole temperatures were within normal limits and the lake level remained unchanged. During 8-9 April steam plumes rose 100-300 m and drifted SW. As of 1-2 May 2020 only weak steaming and fumarolic activity from fissure vents along the Daang Kastila trail was observed. Precise leveling measurements conducted during 13-21 July along the NE, SE, and SW flanks detected minimal inflation. [1] It is in the province of Batangas and is the second most active volcano in the Philippines with 34 historical eruptions. Located on Taal Lake on the island of Luzon, the picturesque volcano and its surrounding shores have long been popular with tourists. There was a green lake, a yellow lake, a red lake and some holes filled with hot water from which steam issued. [45] On March 9, 2021, PHIVOLCS raised the alert level from 1 to 2. Booming sounds were heard at 1400 in Talisay, Batangas (4 km NNE from the Main Crater), and at 1404 volcanic tremor and earthquakes felt locally were accompanied by an eruption plume that rose 1 km; ash fell to the SSW. On 5 July the Alert Level was lowered from 2 to 1. Philippine Institute of Volcanology and Seismology (PHIVOLCS), Disaster Response Operations Monitoring and Information Center (DROMIC), United Nations Office for the Coordination of Humanitarian Affairs, Smithsonian / USGS Weekly Volcanic Activity Report, Eruptions, Earthquakes & Emissions Application, The National Disaster Risk Reduction and Management Council (NDRRMC), https://doi.org/10.1016/j.jvolgeores.2013.11.005, Department of Mineral Sciences collections, World Organization of Volcano Observatories (WOVO), GVMID Data on Volcano Monitoring Infrastructure, Incorporated Research Institutions for Seismology (IRIS), Large Magnitude Explosive Volcanic Eruptions (LaMEVE), Volcano Global Risk Identification and Analysis Project (VOGRIPA), Integrated Earth Data Applications (IEDA), WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. 5 September: Individual eruptive bursts contained a greater proportion of ash and large fragments than those of previous days. 2, p. 19-68. Taal eruptive activity commenced at 0615 on 29 October. [44], In February 2021, residents from Taal Volcano Island were preemptively evacuated due to the volcano's increasing activity. Information Contacts: Manila Times-Journal. [9], Taal Volcano is part of a chain of volcanoes lining the western edge of the island of Luzon. During 13-14 June the seismic network recorded 13 periods of volcanic tremor with durations from 1 to 270 minutes. Most of the earthquakes were very shallow (less than 5 km deep) beneath Taal Volcano Island (TVI) and the NE part of Taal Lake. In 2019, Alert Level 1 was raised on the volcano because of frequent volcanic activities since March. Night and early morning observations 30 October showed ejection of ash and fragments to heights of 600-700 feet at about 90-minute intervals. From November 1215, 1878, ashes ejected by the volcano covered the entire island. [21][20], The Main Crater began experiencing further activity on August 11, 1749, and its eruptions were particularly violent (VEI = 4) until 1753. Near 1730 a black column of ash started to burst out from a smaller vent on the inner western slope of the 1969 crater. Increased seismic activity continued through 16 February; from 0800 on 15 February to 0800 on 16 February there were a total of 98 earthquakes. The entire Volcano Island is a Permanent Danger Zone and permanent settlement is strictly prohibited. Tilt data showed a minor but abrupt inflation signal on 17 May; slow and steady inflation of the Taal region was recorded by multiple instruments after the January 2020 eruption. Taal (also known as Talisay) is a lake-filled, 15 x 20 km caldera located on SW Luzon Island 65 km S of Manila (figure 9). PHIVOLCS reported that unrest at Taal continued during 13-20 July. Instead of rising from the ground as a distinct, singular dome like its neighbor, Mayon, Taal consists of multiple stratovolcanoes, conical hills, and craters of all shapes and sizes.These features have grown together to form the 5-kilometer (3 mile) wide Volcano Island, one of the Philippines' most volcanically active areas. These events added to the totals of 866 volcanic tremor events and 141 low-frequency volcanic earthquakes recorded during 13 February-9 March. The Philippine Institute of Volcanology and Seismologyhas announced a Alert Level 4, indicating a hazardous explosion within hours or days. Taal Volcano stands at 1,020 feet and has 47 craters and 4 maars (volcanic craters caused by an eruption occurring when old groundwater is in contact with hot rock or magma). The massive flows from the two eruptions eventually covered the bay created by the 1965 eruption, reaching the shore of Lake Taal. On 8 June 2010, PHIVOLCS raised the Alert Level for Taal to 2 because of changes in several monitored parameters that began in late April. By 1300 on the 13th lava fountaining generated 800-m-tall, dark gray, steam-laden ash plumes that drifted SW. Sulfur dioxide emissions averaged 5,299 metric tons/day (t/d) on 13 January and dispersed NNE (figure 19). PHIVOLCS strongly recommended no entry onto the island, and access to the Main Crater, Daang Kastila fissure (along the walking trail), and boating on Taal Lake was strictly prohibited. PHIVOLCS reminded the public that the entire Taal Volcano Island is a Permanent Danger Zone (PDZ). Temperature measurements of the main crater lake did not increase further, remaining between 33-34C. Card 0130 (14 October 1968) Philippine Volcanology Commission, via the American Embassy, Manila. The Taal volcano roared to life last weekend for the first time in more than 40 years, sending a massive plume of volcanic ash towering over the Philippines.This was the first time that Taal has erupted since 1977, an event that marked the end of an active period for the volcano that had begun in 1965. During 29 January-4 February sulfur dioxide emissions ranged to a high of 231 t/d (on 3 February). The Alert Level was raised to 2 (on a scale of 0-5) because of increased seismicity and carbon dioxide emissions. Galgana, G. A., Newman, A. V., Hamburger, M. W., & Solidum, R. U., 2014. PHIVOLCS reported that during 8-9 April steam plumes rose 100-300 m above the Taals main vent and drifted SW. Weak steaming (plumes up to 20 m high) from ground cracks was visible during 8-14 April along the Daang Kastila trail which connects the N part of Volcano Island to the N part of the main crater. PHIVOLCS reported that a deformation survey of Taal conducted in December 2010 showed slight inflation as compared to a survey conducted in September 2010. Steady steam emissions were visible during 17-21 January. PHIVOLCS noted the continuing state of elevated unrest, reminding the public that the Alert Level for Taal remained at 2 (on a scale of 0-5). The initial eruptive activity was characterized by increased steaming from at least five vents in Main Crater and phreatic explosions that generated 100-m-high plumes. [38] The volcano produced volcanic lightning above its crater with ash clouds. Though not topographically prominent, its prehistorical eruptions have greatly changed the landscape of SW Luzon. The island is composed of coalescing small stratovolcanoes, tuff rings, and scoria cones that have grown about 25% in area during historical time. No inflation was observed. Five hybrid events were detected during 14-15 March. In response to growing instability PHIVOLCS elevated their alert status to Alert Level 3 on 11 March, suggesting that eruptive activity could occur within a period of weeks. ", Card 0820 (10 November 1969) New cone rapidly growing on the SE slope of the 1968 crater, "Taal volcano is rapidly building a new cone southwest of Volcano Island on the southeastern slope of the 600-foot-high crater created by last year's eruption in Kaygabok. Philippines' second most active volcano, Taal Volcano is located at a distance of about 60 kilometres from Manila. , Batangas City. Ejecta has been primarily vertical but occasionally radial. Sources: Philippine Institute of Volcanology and Seismology (PHIVOLCS); Agence France-Presse (AFP). Sustained ejection of steam, ash, and small amounts of larger incandescent volcanic materials from the new active vent have enlarged the crater and reduced the height of the terminal cone to a few meters. The first recorded eruption occurred in 1572, the year Augustinian friars founded the town of Taal on the shores of the lake (on what is now San Nicolas, Batangas). Another peculiarity of the geologic aspects of Taal is the fact that no sulphur has been found on the volcano. Since 26 April, the number and magnitude of volcanic earthquakes had increased. These reports highlight the difficulty of establishing firm estimates on both the movement and behavior of people in a volcanic crisis. PHIVOLCS reported that a December 2010 deformation survey showed slight inflation compared to a September 2010 survey. Continuing recording of harmonic tremors and observable pulsating vent flows seems to indicate vibration of lava to surface. A more violent event happened on September 24, 1716, blowing out the entire southeastern portion of the crater of Calauit, opposite Mount Macolod. Strict enforcement of precautionary measures under phase on of Operations Taal is now being observed.". The Alert Level remained at 1 (on a scale of 0-5). Remobilized ash drifted SW on 22 January due to strong low winds, affecting the towns of Lemery (16 km SW) and Agoncillo, and rose as high as 5.8 km altitude as reported by pilots. In concert with the newly elevated alert level, the Manila Flight Information office issued a volcanic ash advisory in a NOTAM (Notice To Airmen, a notice to the aviation and meteorological communities) to avoid flying over the volcano. 7 October: Continuous heavy ashfall forced the evacuation of five towns up to 16 km E and N of the vent. Low-frequency volcanic earthquakes were detected on 2 June, and during the previous day high-frequency earthquakes were noted. Diffuse steam plumes from fumarolic vents in the Main Crater rose as high as 40 m. Daily measurements of sulfur dioxide emissions were 837-1,109 tonnes/day. Initial earthquake locations showed epicenters dispersed in the vicinity of Main Crater, to the NNW near Binintiang Malaki, and to the SSE near Calauit. The eruption had a Volcanic Explosivity Index (VEI) of 4 and produced a base surge that sandblasted objects up to 8 km away. Taal Volcano. Low-level background tremor that had begun at 0905 on 8 April continued. Geochemistry of lavas from Taal Volcano, southwest Luzon, Philippines. Within the lake rises Volcano Island (984 feet [300 metres]), which itself contains another small crater (Yellow Lake). The caldera rim consists of deeply eroded hills and PHIVOLCS strongly recommended no entry onto the island, and access to the Main Crater and Daang Kastila fissure (along the walking trail) was strictly prohibited. It has also urged the evacuation of areas within 14km of the volcano. A deformation survey conducted around Volcano Island from April 26 to May 3 showed that the volcano edifice had inflated slightly relative to the April 511 survey.[31]. Slow and steady inflation of the Taal region was recorded by multiple instruments after the January 2020 eruption. The maps database originated over 30 years ago, but was only recently updated and connected to our main database. For the 24-hour period beginning 1530 on 9 October through 1530 on 10 October. Card 0316 (15 December 1968) Philippine Volcanology Commission, via the American Embassy, Manila. Continued seismicity and changes to crater lake. Eruptions were nearly vertical with a slight southward component; the resulting clouds reached more than 2,000 m in the morning, but were limited to 300 m by strong SW winds in the afternoon. Neumann van Padang M, 1953. This report covers activity during January through February 2020 including the 12 to 22 January eruption, and is based on reports by Philippine Institute of Volcanology and Seismology (PHIVOLCS), satellite data, geophysical data, and media reports. Information Contacts: American Embassy, Manila; Father Hennessey, Manila Observatory; Philippine Volcanology Commission, Manila. [30] Frequency peaked at about 115 tremors on May 30 with a maximum intensity of IV, accompanied by rumbling sounds. The lake engulfs a large island with several thousand residents, Volcano Island, the place where all historical eruptions have vented (figures 10 and 11). Seismologists and area residents noticed a significant increase in seismicity beginning on 12 March (figure 4). PHIVOLCS reported that field measurements conducted on 24 May at the E sector inside Taal's Main Crater Lake showed that the water temperature slightly increased from 32.5 to 32.8 degrees Celsius, the pH value became more slightly acidic decreasing from 2.83 to 2.67, and the water level increased by 4 cm. A Japanese refraction seismic experiment recently attempted to delineate a shallow (1-2 km deep) magma chamber beneath Volcano Island that was detected in a similar experiment in 1993. According to the Disaster Response Operations Monitoring and Information Center (DROMIC) there were a total of 53,832 people dispersed to 244 evacuation centers by 1800 on 15 January. Lapilli (2-64 mm in diameter) fell in Tanauan and Talisay; Tagaytay City (12 km N); Nuvali (25 km NNE) and Sta. Twenty six of these are tuff cones, five are cinder cones, and four are maars. Card 0820 (10 November 1969) Philippine Commission on Volcanology; J. J. Hennessey, S.J., Manila Observatory, Manila. During the early morning of 31 October, cauliflower-shaped steam clouds reaching 100 m height were observed, containing only minimal amounts of ash. Steaming from the N and NE sides of Main Crater occasionally intensified. in Taal Volcano Bulletin. He said, however, that a bigger blast can be reasonably expected to occur because more volcanic energy will be needed this time to throw out tons of earth and lava blocking the exit. The increase in seismicity at Taal reflects a low-level episode of unrest. Steaming at the N and NE sides of the main crater occasionally intensified and was occasionally accompanied by hissing sounds. Retrieved January 15, 2020. About 6,000 people had been evacuated but the number was expected to rise. Residents described heavy ashfall, low visibility, and fallen trees. 15 September: Activity increased around 0700. Seismicity decreased in May 1991, and no more than five earthquakes were recorded daily in early August . Sometime during this interval the temperature of surface waters of the main crater lake also rose by 3C. Harmonic tremor amplitude increased. Tabaro eruption site, Taal volcano, Philippines: Philippine Journal of Volcanology, v. 1, no. New ground cracks were observed on 13 January in Sinisian (18 km SW), Mahabang Dahilig (14 km SW), Dayapan (15 km SW), Palanas (17 km SW), Sangalang (17 km SW), and Poblacion (19 km SW) Lemery; Pansipit (11 km SW), Agoncillo; Poblacion 1, Poblacion 2, Poblacion 3, Poblacion 5 (all around 17 km SW), Talisay, and Poblacion (11 km SW), San Nicolas (figure 21). Surface observations indicated no change in the main crater lake area. The initial evacuation procedure remained in effect in late January.". Seven volcanic quakes and tremors were recorded in a 24-hour period. Intermittent non-eruptive unrest during 2008-2010. The eruption brought great changes in the interior of the crater, according to chroniclers of that time. June 29, 2017 at 5:18 am. The following report was received from the American Embassy in Manila on 14 October 1968. Increase in recorded earthquakes; minor deformation. Show less. But the story is far from over. The main crater lake temperature remained at 31C. Earthquake swarm, deformation, and new fissures document apparent intrusion; evacuations. During 25-27 and 29-30 January, PHIVOLCS reported that up to six volcanic earthquakes at Taal were detected daily by the seismic network. One hybrid earthquake was recorded during 11-12 March. Res., 271: 11-23. https://doi.org/10.1016/j.jvolgeores.2013.11.005, Remarks: Deformation at Taal Volcano can be modeled by spherical Mogi source beneath Volcano Island''s central crater and is likely magmatic in origin. Wet ash fell as far away as Quezon City (75 km N). An intensity 2 quake rocked Taal volcano at 0829 today and steam came out in the Kaygabok eruption site along a NE-SW rift leading to the main crater. Information Contacts: Card 0288 (13 December 1968) Philippine Volcanology Commission, via the American Embassy, Manila. Catane S G, Taniguchi H, Goto A, Givero A P, Mandanas A A, 2005. 9 September: The strongest explosion of the eruption produced base surges that moved over the 1965 and 1966 craters. PHIVOLCS reported that white steam-laden plumes rose as high as 800 m above Taals main vent during 22-28 January and drifted SW and NE; ash emissions ceased around 0500 on 22 January. PHIVOLCS reported that unrest at Taal continued during 9-15 June. Despite absence rains for last two or three days which might have brought about condensation steaming and emission sulfuric vapors very strong this morning. Surface observations indicated no change in the main crater lake area. According to Friar Miguel Saderra Maso, "Before [the eruption], the bottom looked very deep and seemed unfathomable, but at the bottom, a liquid mass was seen in continual ebullition. 2, p. 18-20. According to news articles, the number of people that had evacuated from around Taal rose to 1,375. Magma was intruding towards the surface, as indicated by continuing high rates of CO2 emissions in the Main Crater Lake and sustained seismic activity. Seismicity remained at elevated levels, and the island was partially evacuated as of mid-April. Information Contacts: Philippine Commission on Volcanology; Director, Manila Observatory, Manila. 18 September: Ash and sulfur emission decreased slightly in the evening. Relatively high unrest manifested by seismic swarms including increasing occurrence of low frequency earthquakes and/or harmonic tremor (some events felt). Satellite images showed that the Main Crater lake was gone and new craters had formed inside Main Crater and on the N flank. The municipality of Taal and the Taa-lan River (now known as Pansipit River) were named after the Taa-lan tree, which grows along the river. Santos G G, Wainerdi R E, 1969. Deformation and ground cracks. The Earth Observatory of Singapore reported that the International Data Center (IDC) for the Comprehensive test Ban Treaty (CTBT) in Vienna noted initial infrasound detections at 1450 that day. Hazardous eruption in progress. The possibility of a new eruption occurring beneath Lake Taal or near Mt. Overall, seismicity over the past month indicated increased magmatic and hydrothermal activity at shallow depths beneath Taal Volcano Island (TVI). Science, 151: 955-960. During 15-16 January 10 volcanic earthquakes were detected; two earthquakes were felt by residents in barangay (neighborhood) Pira-piraso, on the N side of the island. Twelve of these events were felt at Intensity I-IV by residents of Pira-piraso, Alas-as, and Calauit located in the NE, SW, and SE sectors of Volcano Island, respectively. A series of volcanic earthquakes was recorded on 9 January 2005. Located in the province of Batangas, the volcano is one of the most active volcanoes . 13 September: Voluminous quantities of steam and ash were emitted, causing ashfalls at towns up to 10 km E of the vent. PHIVOLCS, 2018-. [3] Each of these eruptions created extensive ignimbrite deposits reaching as far away as present-day Manila. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has ordered a "total evacuation" for people in high-risk areas within a 14-kilometer radius . Rosa (32 km NNW), Laguna; Dasmarias (32 km N), Bacoor (44 km N), and Silang (22 km N), Cavite; Malolos (93 km N), San Jose Del Monte (87 km N), and Meycauayan (80 km N), Bulacan; Antipolo (68 km NNE), Rizal; Muntinlupa (43 km N), Las Pias (47 km N), Marikina (70 km NNE), Paraaque (51 km N), Pasig (62 km NNE), Quezon City, Mandaluyong (62 km N), San Juan (64 km N), Manila; Makati City (59 km N) and Taguig City (55 km N). The eruption of the volcano claimed a reported 1100 lives and injured 199, although it is assumed that more perished than the official records show. Its geology and location could soon combine in . [50][51] Five eruptions were recorded on July 7. A PHIVOLCS report for 0800 on the 13th through 0800 on 14 January noted that lava fountaining had continued, with steam-rich ash plumes reaching around 2 km above the volcano and dispersing ash SE and W of Main Crater. Taal volcano is located around 50 kilometers away from Manila, capital of the Philippines. Ruelo, H.B., 1983, Morphology and crater development of the Mt. 2, p. 19-68. Temperature and acidity of the lake were at normal levels, and the color had not changed. The observed steam plumes rose as high as 300 m during 5-11 February and drifted SW. Sulfur dioxide emissions averaged around 250 t/d during 22-26 January; emissions were 87 t/d on 27 January and below detectable limits the next day. Entry into Taal Volcano Island, Taal's permanent danger zone or PDZ must be . Thermal and steaming conditions remained unchanged from normal levels. These models will, we hope, be useful as norms for comparison for workers in ancient terrains. The idea for this book came into being between 1981 and 1982 when J. V. W. came to Monash University to take up a Monash Postdoctoral Fellowship. The increased bubbling suggests significantly higher pressure beneath the stratovolcano, consistent with the postulated shallow magma chamber. Sulfur dioxide emissions were low at 140 t/d. Harmonic tremor was also reported, interpreted as due to magma intruding below the stratovolcano's central crater. The DROMIC report stated that 3,027 people were in 20 evacuation centers, and 2,759 people were in private residences by 6 July. Show more. Harmonic tremor continues, but no eruption, "The renewed activity of Taal on 9 November resulted in the formation of a circular conelet protruding a few meters from the floor of the elongated 1976 crater. Immediately after the explosion, the various colored lakes had disappeared and in their place was one large lake, about ten feet below the level of the lake surrounding the island. Harmonic tremor amplitude began to increase at 0330. The maps shown below have been scanned from the GVP map archives and include the volcano on this page. Intense unrest, continuing seismic swarms, including harmonic tremor and/or low frequency earthquakes which are usually felt, profuse steaming along existing and perhaps new vents and fissures. Activity had migrated back to the elongate main vent. Weak steaming (plumes 10-20 m high) from ground cracks was visible during 5-11 February along the Daang Kastila trail which connects the N part of Volcano Island to the N part of the main crater. The DROMIC report stated that 3,839 people were in evacuation centers or private residences by 20 July. Lava extrusion continued without let up, the subterminal flow breaking out into four or five cascades over a rift formed by crushed lava near the northern base of the old 1968 cone. Peak measurements coincided with periods of vigorous upwelling at the Main Crater Lake; the upwelling was continuous from 1800 on 9 June to 1000 on 10 June, producing steam plumes that rose 1.5 km and drifted mainly NW. The main Vulcan point situated in the main crater lake, which is on the volcano island that is in Taal lake, which is in the main island of the Philippines (Luzon). Dropping water levels of Taal Lake were first observed in some areas on 16 January but reported to be lake-wide the next day. Fissures on the N flank produced 500-m-tall lava fountains. The stratovolcano sits in the center of a 15 x 22 km caldera occupied by Taal lake. Taal is only 30 miles (50 kilometers) south of Manila on the island of Luzon in the Philippines. A geological wonder, the volcano is located on an island and . The eruption spewed ashes to Calabarzon, Metro Manila, some parts of Central Luzon, and Pangasinan, in the Ilocos Region, which cancelled classes, work schedules, and flights. A sudden increase in local seismicity began early 14 February, reaching a peak of 385 high-frequency earthquakes recorded between 1200 on 14 February and 0600 on 15 February. A maximum of 19 events/day was recorded on 31 October; 5 of the events were felt by residents of Agoncillo, 10.7 km SW of the crater on the W shore of Taal Lake (figure 3).
