PHIVOLCS issued a special notice for Kanlaon at 1400 on 3 July, noting increased earthquake activity beneath the summit. A total of 41 volcanic earthquakes were recorded by the seismic network beginning at 0500 on 30 June, including seven shallow tornillo signals indicating gas movement through fractures in the upper flanks. Ground deformation data from continuous GPS indicated minor, short-term inflation of the lower and mid-flanks of the volcano since January 2022, consistent with continuous electronic tilt data that had recorded inflation on the SE flanks since mid-March 2022. ...
