MANILA, Philippines — Fourteen volcanic earthquakes, including four volcanic tremors, were recorded at Taal Volcano in the past 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Wednesday.

The state seismologist defined volcanic earthquakes as those that come from an active volcano and are distinguished by their “mode of arrivals, periods, amplitudes, etc.”

Volcanic tremors, on the other hand, are “continuous seismic signal with regular or irregular sine wave appearance and low frequencies.”

The tremors lasted from two to three minutes each, according to Phivolcs’ bulletin.

It also noted that alert level 1 remains over the volcano.

Meanwhile, it was reported that Taal Volcano released 3,504 tons of sulfur dioxide last April 22.

Plumes measuring 600 meters high were also released in the southwest and west-northwest directions.

Phivolcs advised that entry to Taal Volcano Island remains prohibited, particularly in the main crater and Daang Kastila fissures.

It also warned against sudden phreatic explosions, volcanic earthquakes, slim ashfall, and toxic gas release.

On Tuesday, the state seismologist reported 12 volcanic earthquakes and eight volcanic tremors lasting two to four minutes at Taal Volcano.

It also emitted 3,504 metric tons of sulfur dioxide, which rose 900 meters.

Last April 20, the state seismologist observed three “short-lived” phreatic eruptions at Taal Volcano’s main crater.

Phivolcs said that continued emission of hot volcanic gases at the volcano’s main crater could have triggered the phreatic eruptions.
