The Philippine Institute of Volcanology and Seismology (Phivolcs) said yesterday that twenty volcanic earthquakes have been recorded on the Taal island in Batangas over the past 24 hours.
State seismologists observed weak steam activity, which reached five meters in height from the vents of the main crater between 8 am Saturday and 8 am yesterday.
The volcano is still under warning level 1, which means it is still in an abnormal state, the agency said.
On August 18, 20 meters high steam was ejected from the vents of the main crater.
Renato Solidum Jr., Deputy Minister for Science and Phivolcs Officer, said earlier that the steam emissions in Taale are "normal".
According to government seismologists, sudden steam or phreatic explosions, volcanic earthquakes, minor ash falls and fatal accumulations or outbursts of volcanic gas can occur and threaten territories on the island of Taal.
Entry to the island, which is a permanent danger zone of the volcano, especially in the vicinity of the main crater and in the Daang Kastila crack, is prohibited.
Taal, the country's second most active volcano, erupted in January, displacing over 370,000 people.
