Taal records 4 volcanic tremors, emits 1,200-meter tall plume

The Philippine Institute of Volcanology and Seismology (Phivolcs) has logged four volcanic tremors and a voluminous plume at Taal Volcano in the past 24 hours.
In its 8 a.m. bulletin issued on Saturday, Oct. 1, Phivolcs said that two of the volcanic earthquakes have lasted one to two minutes long.
Phivolcs also observed a “voluminous” plume measuring 1,200 meters high from the main crater of Taal Volcano.
Taal Volcano’s sulfur dioxide averaged 7,015 tons per day, as of Sept. 30, it added.
Phivolcs said Taal Volcano remains under Alert Level 1, which means it is still in an abnormal condition and should not be interpreted to have ceased unrest nor ceased the threat of eruptive activity.
Sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within the TVI.
“Should an uptrend or pronounced change in monitored parameters forewarn of renewed unrest, the alert level may be raised back to Alert Level 2,” it said.
Phivolcs said that entry into TVI, which is Taal’s permanent danger zone or PDZ, especially the vicinities of the main crater and the Daang Kastila fissure, must remain strictly prohibited.
