Phivolcs lowers Taal Volcano alert to level 1

UNTV News   •   March 19, 2020   •   1129

MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (Phivolcs) on Thursday said it has downgraded the alert on Taal Volcano to level 1 following the decrease in volcanic quakes and surface activity at the main crater.

In its bulletin, Phivolcs said the Taal Volcano’s condition in the succeeding four weeks after its alert was lowered to level 2, has been characterized by low-level volcanic earthquake activity, stabilizing ground deformation of the Taal Caldera and the Taal Volcano Island edifices, and weak surface activity at the Main Crater and the Daang Kastila fissure.

“DOST-PHIVOLCS is lowering the alert status of Taal Volcano from Alert Level 2 to Alert Level 1 to reflect the overall decreasing trend in the level of monitoring parameters,” its bulletin reads.

State volcanologists said that alert level 1 means that the volcano is still in “abnormal condition,” and that this “should not be interpreted that unrest has ceased or that the threat of an eruption has disappeared.”

Under alert level 1, 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 Taal Volcano Island.

The alert level may be raised back to alert level 2 “should pronounced change in monitored parameters forewarn of renewed unrest,” Phivolcs said.

The agency reminded residents that entry to Taal’s permanent danger zone, especially the vicinities of the Main Crater and the Daang Kastila fissure, remains strictly prohibited. 

The Taal Volcano was placed under alert level 4 when it spewed ash on January 12 which sent thousands of residents to temporary shelters and disrupted businesses in surrounding areas.

It was later lowered to alert level 2 several weeks later due to decreased unrest. — ROBIE DE GUZMAN

MANILA, Philippines—The Philippine Institute of Volcanology and Seismology (Phivolcs) has recorded an increasing number of tremors in Taal Volcano this week.

Based on the agency’s report released on Friday (February 26), the state seismologists recorded 113 volcanic tremors with an average duration of 34 minutes in the past 24 hours. This is a significant jump from yesterday when 69 volcanic tremors were recorded.

Phivolcs also reported an emission of weak steam-ladden fumes from the vents of the volcano’s main crater.

Despite the increase in tremors, Taal remains at Alert Level 1. The public is advised — especially residents near Taal — to remain in a safe area as more volcanic earthquakes, steam emissions, and minor ashfall can occur. Several residents have already been evacuated last week.

Phivolcs also reiterated that entry into Taal’s permanent danger zone remains prohibited. AAC

It also has more than P8.3 million standby funds that can be used to procure additional emergency relief supplies.

“The FO has also placed its Emergency Operations Center (EOC) under heightened alert to monitor volcanic activities and to provide technical assistance to municipalities that will require assistance,” according to the DSWD.
