Taal Volcano quakes increase in number in 24 hours

According to the most recent bulletin of the Philippine Institute of Volcanology and Seismology (Phivolcs), there were 11 earthquakes produced by the activity of the Taal Volcano today, April 12, 2011. This is 4 quakes more than yesterday's recorded volcanic quakes.

The bulletin added that the carbon dioxide emissions of the Volcano is still in high levels which suggest anomalous gas release from the magma at depth. The Alert Level II hoisted last Saturday has not been lifted due to the increased activity of Taal Volcano.

The Institute had advised the public that the Main Crater, Daang Kastila Trail and Mt. Tabaro (1965 -1977 Eruption Site) are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate.

In today's episode of TV Patrol, it was reported that there were cracks noted on the walls and floors of the houses and on the roads in Talisay, Batangas which is 10 km away from Taal Volcano. The Phivolcs is still to investigate what caused the cracks.

Taal Volcano is located in Batangas and is one of the most active volcanoes in the Philippines. During its past eruptions, it has killed more than 5,000 people to date. There has been a total of 33 recorded eruptions at Taal since 1572.

Taal Volcano Bulletin - April 11, 2011

Courtesy of the Philippine Institute of Volcanology and Seismology, here's the Institute's most recent bulletin (dated April 1, 2011) of the Taal Volcano which provides information of the current activity of the volcano:

Taal Volcano’s (14.0000°N, 120.9833°E) seismic network recorded seven (7) volcanic earthquakes during the past 24 hours. Water temperature slightly increased from 30.0°C to 30.5°C. Gas measurements conducted at Taal Main Crater Lake last January, February and March 2011 yielded carbon dioxide (CO2) emission values of 2,250 tonnes per day (t/d), 1,875 t/d and 4,670 t/d respectively. The remarkable increase in C02 concentration indicates anomalous gas release from the magma at depth. Result of the ground deformation survey (precise leveling) conducted around the Volcano Island last 05-11 April 2011 showed that volcano edifice is slightly inflated as compared with the 02-09 February 2011 survey.

Alert Level 2 is hoisted over Taal Volcano with the interpretation that magma has been intruding towards the surface, as manifested by CO2 being released in the Main Crater Lake and increase in seismic activity. Hence, PHIVOLCS advises the public that the Main Crater, Daang Kastila Trail and Mt. Tabaro (1965 -1977 Eruption Site) are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate. Breathing air with high concentration of gases can be lethal to human, animals and even cause damage to vegetation. In addition, it is reminded that entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strictly not recommended. DOST-PHIVOLCS is closely monitoring Taal Volcano’s activity and any new significant development will be immediately relayed to all concerned.

Taal Volcano is located in Batangas and is one of the most active volcanoes in the Philippines. During its past eruptions, it has killed more than 5,000 people to date. There has been a total of 33 recorded eruptions at Taal since 1572.
