The activity of the volcano remains unchanged - seismic unrest and degassing activity continue at elevated levels, indicating that magma is moving and accumulating underneath the surface and might cause new eruptions at any time.
On 22 May PHIVOLCS s surveillance cameras observed increasingly gas-steam plumes rising from the crater lake which rose
5,000 ft (1,500 m) above the Main Crater and drifted southwest.
On 21 May, sulfur dioxide (SO2) emissions reached to a 3426 tonnes/day.
The Main Crater Lake temperature reached to a 71.8°C with a pH of 1.59 on 4 March caused by volcanic gas reaching the shallow hydrothermal system that feeds into the lake accompanied by degassing.
