LUCENA CITY — At least 12 volcanic earthquakes in Taal Volcano were detected over the last 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported on Tuesday, April 23.
In its bulletin, the state volcanologist said the earthquakes on Monday were accompanied by eight volcanic tremors that lasted from two to four minutes.
On Saturday, April 20, Taal Volcano recorded 17 volcanic earthquakes accompanied by six volcanic tremors that also lasted two to four minutes.
The state volcanologists also recorded four short-lived phreatic eruptions during the observation period on Saturday.

The state volcanologists in a public advisory explained that recent phreatic eruptions at Taal were probably caused by ongoing emission of hot volcanic gases, with the potential for more similar activity.
Yet, they stressed that the unrest is unlikely to escalate into a magmatic eruption, citing background levels of volcanic seismicity and ground deformation.
Taal Volcano is still under alert level 1 (low level of volcanic unrest), Phivolcs said.
The agency reminded the public that Taal Volcano remained in an “abnormal condition” and “should not be interpreted to have ceased unrest nor ceased the threat of eruptive activity.” #
