The Phivolcs reported a phreatic eruption, on October 19 at 4:58 local, localized to the vents on the upper flanks southeast of Bulusan.

Cloud cover did not allow continuous observation of this event, which marked the seismographs for 9 minutes. A plume estimated at 1,000 meters could be seen during an observation near the active vent.
The permanent danger zone (PDZ) is maintained at 4 km, but extended danger zone (EDZ) of 2 km, encompassing Mapaso, San Roque and Patag, was declared due to phreatic eruption hazards.
