Up to 5 small high-frequency earthquakes were recorded daily August. No earthquakes were felt during this time. Close monitoring of the volcano continued. Earthquake swarm, deformation, and new fissures document apparent intrusion; evacuations. A sudden increase in local seismicity began early 14 February, reaching a peak of high-frequency earthquakes recorded between on 14 February and on 15 February.
Many were felt in 6 towns near the shores of Lake Taal, which fills the 15 x 22 km caldera. The active cone forms an island near the center of Lake Taal. According to press reports, volcanologists observed that water temperature in the island's crater lake 1. A Notice to Airmen was issued at on 14 February, advising all aircraft to exercise caution and avoid flying over the area. Seismicity quickly decreased on 15 February, and only 14 earthquakes were recorded during a hour period on 16 February.
Geologists suggested that the activity represented a magma intrusion episode that appeared to have stopped.
A similar episode of increased seismicity occurred in March-April , with as many as 64 earthquakes 25 March recorded under the E side of the volcano Several thousand people were evacuated from the island. Seismicity decreased in May , and no more than five earthquakes were recorded daily in early August. No inflation was observed. After a brief episode of increased seismicity, deformation, and increased crater lake temperatures on February, activity returned to more normal levels.
Fieldwork by Univ of Savoie personnel indicated that temperatures of the main crater lake were gradually declining, and that seismicity was near background levels. All measurable deformation seemed to have occurred on 14 February. Most residents of Taal island have returned home. Information Contacts: C. Newhall , USGS. Beginning in late February , Taal stratovolcano underwent increases in seismicity, deformation, temperature, and other signs of growing instability.
The stratovolcano sits in the center of a 15 x 22 km caldera occupied by Taal lake. Taal stratovolcano, which is sometimes also referred to as either Volcano Island or Taal Island, has a central, 6-km-diameter crater lake termed the main crater lake figures 5 and 6.
After 22 February, the seismic station located on the N shore of the main crater lake station MRCZ detected swarms of small high-frequency events, swarms that went undetected elsewhere, presumably because they had shallow epicenters located close to the station. Seismicity continued to grow; during the hour intervals beginning at on 13 and 14 March there were and events, respectively. Many events took place at shallow depths typically shallower than 3 km , beneath the central-to-SW portion of the caldera.
Harmonic tremor was also reported, interpreted as due to magma intruding below the stratovolcano's central crater.
Deformation and precise leveling surveys conducted February indicated slight inflation of the SW portion of Volcano Island. In mid-March an uplift of 14 cm was measured on the E side of the island; on 13 March both the N and SE sides inflated on the order of cm. Around the same time researchers found two newly formed open cracks or fissures. The fissures had opened mm, consistent with inflation of the edifice. Newhall and Dzurisin referred to extensive NE-trending ground cracks outside the caldera associated with the eruption.
On 12 March, data from acoustic sensors located about 25 m above the bottom of the main crater lake showed a significant increase in bubbling activity, which declined slightly the next day.
The increased bubbling suggests significantly higher pressure beneath the stratovolcano, consistent with the postulated shallow magma chamber. 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. They also mentioned " The reports were unclear, however, on both the number of people evacuated from Volcano Island, and the circumstances of their departure; one report told of hundreds who fled, the other told of thousands who were ordered to flee.
Several of these news reports also stated that some villagers from the island were unwilling to leave their homes. One report said "Farmers staying on the island have rented out horses to tourists from Manila so they can ride to the crater lake to photograph steam rising from rocks around the rim.
These reports highlight the difficulty of establishing firm estimates on both the movement and behavior of people in a volcanic crisis. Taal's most recent unrest took place in and involved elevated seismicity, deformation, and crater lake temperatures that lasted from several days to months.
These conditions did not lead to eruptions. In many other cases, 34 since , Taal did discharge, and in six cases these eruptions led to fatalities. In Taal ejected an estimated 9 x 10 7 m 3 of material. The eruption had a Volcanic Explosivity Index VEI of 4 and produced a base surge that sandblasted objects up to 8 km away. The volcano monitoring system at Taal has been improved since the crisis. Improvements include telemetry-linked sensors for seismic, temperature, radon gas, and lake geochemistry.
A Japanese refraction seismic experiment recently attempted to delineate a shallow km deep magma chamber beneath Volcano Island that was detected in a similar experiment in Newhall, C. Geological Survey Bulletin , v. Ruelo, Hernulfo B. The Taal seismic monitoring network began to record significant volcanic earthquakes on 23 September In general, the numbers of these events occurring through 29 October increased, with a maximum 13 earthquakes on 15 October.
Some of these earthquakes were instrumentally recorded with relatively large amplitudes although none were felt by residents on Volcano Island.
Surface observations, however, did not indicate any significant change in the thermal and steam emission characteristics of the Main Crater lake area. The increased seismicity is an indication of a low-level episode of unrest, although at this time there is no clear indication of an impending eruption. A series of volcanic earthquakes was recorded on 9 January Two of these earthquakes, only one minute apart, were felt in Pira-piraso. Several fissures traversing the Daang Kastila Trail are also potentially hazardous as possible sites of future steam emission.
PHIVOLCS is conducting several enhancements of the monitoring system at Taal with deployment of more seismometers and ground-deformation surveillance equipment. The entire Volcano Island is a Permanent Danger Zone and permanent settlement is strictly prohibited.
Garcia Avenue, Univ. The Main Crater Seismic Station recorded 29 volcanic earthquakes during the hour period from hours on 25 September. The earthquakes were accompanied by rumbling sounds.
This seismic activity was notably higher than the usual levels, generally only five or less events detected in 24 hours. Surface thermal observations, however, did not indicate significant change in the thermal and steam emission manifestations of the Main Crater lake area.
The increase in seismicity at Taal reflects a low-level episode of unrest. However, there is still no indication of an impending eruption. Possible precursors, such as increased steam emission, increased temperatures of steam vents at the Main Crater lake waters and adjacent areas are being monitored continuously. The ongoing seismic unrest could intensify in the coming days or weeks so that PHIVOLCS recommends appropriate vigilance by the public when visiting the island.
Elevated seismicity, deformation, and hydrothermal activity during The Main Crater Seismic Station recorded 29 volcanic earthquakes during the 24 hours after on 25 September These earthquakes were accompanied by rumbling sounds.
This seismic activity was notably higher than usual, which during quiet periods is generally only five or less events detected in 24 hours. Surface thermal observations, however, did not indicate significant change in the thermal and steam emission manifestations in the Main Crater Lake area. The increase in seismicity reflected a low-level episode of unrest. Taal manifested a sustained moderate level of seismic activity since 18 November , characterized by occasional large amplitude volcanic earthquakes.
During one hour period, 10 volcanic earthquakes were detected. Ground deformation surveys conducted during 28 November-6 December revealed the edifice inflated The Main Crater lake water became more acidic since 12 September , and the newly formed mud geyser, which is now merged with the Crater Lake due to increase in water level, continues to be very active.
The increasing acidity and hydrothermal activity are probably caused by the injection of hot gases and fluids coming from below the crater floor. Alert Level 1 continued, making the Main Crater off-limits to the public because of the chance of sudden steam explosions and high toxic gas concentrations.
This report discusses Taal seismicity, deformation, and hydrothermal behavior steaming, and temperature changes in lake water at Main Crater that occurred intermittently during , , and The lake engulfs a large island with several thousand residents, Volcano Island, the place where all historical eruptions have vented figures 10 and Restlessness described herein was not confined to the area beneath the island.
On 28 August , ten volcanic earthquakes occurred, two of which were felt and heard as rumbling sounds by residents in the Pira-Piraso village on Volcano Island.
The earthquakes were located NE of the island near the Daang Kastila area below Taal caldera's N rim at estimated depths of 0. The Alert Level remained at 1 scale is , with 0 referring to No Alert. Since 26 April, the number and magnitude of volcanic earthquakes had increased. Most signals were high-frequency earthquakes, but at least one, on 2 June, was low-frequency. Deformation data showed slight inflation since ; measurements taken at the SE side of Taal on 7 June showed further inflation by 3 mm.
PHIVOLCS proposed that the high frequency earthquakes could be the result of active rock fracturing associated with magma intrusion beneath the volcano, and that the fractures could serve as passageways through which hot gases from the intruding magma could escape into the lake.
According to news reports Xinhua, Philippine Daily Inquirer , the more than 5, residents living near Taal were advised to evacuate their homes voluntarily. On 10 June, the Philippine Coast Guard sent five teams of divers and rescue swimmers with rubber boats and medical teams to its forward command post to help evacuate, if necessary, these residents.
A news report Philippine Daily Inquirer , however, indicated that most residents refused to leave without an official order. The number of earthquakes recorded daily gradually declined to background levels beginning the second week of July However, given that field surveys conducted at the Main Crater and at the "New Eruption" site SW edge of Main Crater indicated no anomalous thermal or surface activity.
Field observations on 10 and 18 January revealed no significant changes. Weak steaming from a thermal area inside the main crater was noted and the lake temperature, acidity, and color were normal.
During January , ten volcanic earthquakes were detected, two of which were felt by residents of Pira-Piraso, on the N side of the island. Between January, up to seven daily volcanic earthquakes were detected by the seismic network. Field observations during January revealed an increase in the number of steaming vents inside the main crater and a drop in the lake level there.
The lake water temperature and pH values remained normal. Visual observations on 27 January showed weak steaming at a thermal area in the crater.

In some cases additional feature type, elevation, or location details are provided. Taal is one of the most active volcanoes in the Philippines and has produced some of its most powerful historical eruptions.
Though not topographically prominent, its prehistorical eruptions have greatly changed the landscape of SW Luzon. The 15 x 20 km Talisay Taal caldera is largely filled by Lake Taal, whose km 2 surface lies only 3 m above sea level.
The maximum depth of the lake is m, and several eruptive centers lie submerged beneath the lake. The 5-km-wide Volcano Island in north-central Lake Taal is the location of all historical eruptions.
Powerful pyroclastic flows and surges from historical eruptions have caused many fatalities.

A 3-km-wide caldera is located at the center of Volcano Island, in the Philippines' southern Luzon Island. The 5-km-wide Volcano Island lies within the much larger 15 x 20 km Taal caldera, of which the western wall is seen across Lake Taal in the distance.

Photo by Chris Newhall, U. Taal caldera, seen here from its NW rim, is a 15 x 20 km caldera of Pleistocene and Holocene age. Volcano Island, in the north-central part of Lake Taal, is constructed of coalescing small tuff and scoria cones. Powerful phreatomagmatic explosive eruptions from several locations on the 5-km-wide island have produced deadly pyroclastic surges. The small tuff cone in the center of this photo was produced towards the end of a powerful explosive eruption of Taal in the Philippines.
The eruption from 28 to 30 September originated from a fissure on the SE flank of Volcano Island and produced devastating pyroclastic surges when lake water gained access to the vent. The vent is filled by an inlet of Lake Taal in this post-eruption photo from the S. Eruptions the following year almost completely filled this new inlet.

This m-wide crater formed during an eruption of Taal in That eruption modified cones and craters that had been constructed during yearly eruptions from to within a larger crater that formed during the eruption. This photo from the SW also shows the small crater along the margin of the flat bench at the upper right side of the crater.
The surface of the km 2 lake is only 3 m above sea level. Volcano Island has been the source of explosive eruptions with pyroclastic surges that devastated lakeshore areas.

GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments. Volcanic Hazard Maps The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers or other interested parties to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences.
In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps.
