The seismic activity at the volcano increased yesterday.

PHIVOLCS recorded 136 volcano-tectonic earthquakes beneath the western flanks. 4 volcano-tectonic earthquakes with magnitude M 3.2-4.7 at 1:01, 1:04, 1:34 and 2:06 local time were felt in La Carlota, Bago City, Negros Occidental, Canlaon City and Negros Oriental.
Emissions of gas and steam plumes rose 656 ft (200 m) above the crater and drifted southwest.
On 13 June sulfur dioxide (SO2) emissions reached to a 438 tonnes/day.
GPS measurements detected a slight deflation of the lower and mid slopes since January 2020. Short-term electronic tilt monitoring on the southeastern flanks recorded continuing deflation on the lower slopes but inflation on the mid slopes since April 2020. Phreatic or hydrothermal explosion can occur.
The warning bulletin states that ballistic impacts of volcanic bombs and phreatic eruptions could affect an area of about 4 km distance from the main crater.

Kanlaon volcano (Philippines) - Smithsonian / USGS Weekly Volcanic Activity Report for 17 June-23 June 2020 (Continuing Activity)
PHIVOLCS reported that ground deformation data from continuous GPS measurements at Kanlaon indicated slight deflation of the lower and middle flanks since January. Tilt data from instruments on the SE flank recorded continuing deflation on the lower flanks and inflation of the mid-flank since April 2020. White steam plumes rose 100-200 m above the summit and drifted NW and SW. ... Read all
