MANILA -- Taal volcano's abnormal state intensified Wednesday, with the Philippine Institute of Volcanology and Seismology (Phivolcs) recording 13 earthquakes, one of which was felt at intensity 3 in Barangay Calauit.
The volcano's main crater's temperature also increased slightly to 31.5 degrees Celsius from 30.5 degrees Celsius recorded on Tuesday.
Taal Volcano is still at alert level 2, which means magma has been intruding toward the surface. Visiting the main crater, Daang Kastila Trail and Mount Tabaro is still discouraged.
The National Disaster Risk Reduction and Management Council said it will continue preparations for the possible eruption.
Meanwhile, Mount Bulusan in Sorsogon is also showing signs of activity.
"We were able to record eight quakes in the last 24 hours. However, there were no signs of abnormality since its ash emissions last February 21," Phivolcs said.
Mount Bulusan is still in alert Level 1. (Sunnex)
