The volcano continues at the phase of intense activity over the past month.
The local observatory PHIVOLCS detected 185 volcano-tectonic earthquakes including 176 one-to-sixteen-minute tremors during t24 hours between 11-12 July. This indicates that magma is moving and accumulating underneath the surface and might cause new eruptions at any time.
Sulfur dioxide (SO2) emissions reached to a 6421 tonnes/day on 11 July.
PHIVOLCS's surveillance cameras observed gas-steam plumes rising from the crater lake which rose to an altitude of 4,900 ft (1,500 m) and drifted SW, W and NW.
Ground deformation parameters from electronic tilt, continuous GPS and InSAR monitoring continue to record a very slow and steady inflation and expansion of the Taal region that began after the January 2020 eruption.
