Bulusan (Philippines) - Report for 1 July-7 July 2020 - NEW

PHIVOLCS reported that the seismic network at Bulusan recorded 53 volcanic earthquakes during 3-6 July, including 43 low-frequency events associated with weak shallow hydrothermal or magmatic gas movement.
Despite visible degassing or steaming from the active vent in 2020, increased seismicity may still be followed by phreatic activity at the summit or from flank vents.
Additionally, GPS data indicated short-term inflation since late February.
On 6 July the Alert Level was raised to 1, indicating abnormal conditions, and the public was reminded of the 4-km-radius Permanent Danger Zone (PDZ).
There were 19 volcanic earthquakes recorded during 6-7 July, and diffuse white steam plumes rose from the lower SE vent.
