The seismic network of volcanological observatory PHIVOLCS detected 98 tremor events at less than 1 km depth that lasted in range of 5 to 12 minutes.

The Crater Lake temperature reached 77.1°C and 1.59 pH value of acidification on 12 February.
Fumarolic activity accompanied by emissions of water vapor and gases continue from the vent that rose to 5 m above the crater.
Ground deformation parameters from continuous electronic tilt at the volcano recorded a slight deflation around the summit crater since October last year. Very slow and steady inflation of the Taal region has been recorded by continuous GPS data after the eruption.
