MANILA, Philippines — Three volcanic earthquakes in Taal Volcano were detected over the last 24 hours while Alert Level 1 is still in effect, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported on Sunday.
The earthquakes recorded from September 30 to October 1 were accompanied by one volcanic tremor which lasted five minutes, Phivolcs added.
The recent data is lower than the six volcanic quakes, including five volcanic tremors, logged from September 29 to 30.
