''Over the previous 24 hours the bulletin reports an increase in Mayon’s activity, with 248 earthquakes and tremors recorded by the seismic network, 50 of which ‘were of the explosion type’. Harmonic tremors were continually recorded. Explosions produced ash plumes to 1000 metres above the summit, and the plume drifted south-west. Continuous steaming produced ‘dirty white to light brown’ plumes, and an intensified crater glow was visible at night. Lava has reached approximately 3 km downslope from the crater, while incandescent blocks have descended to between 3 and 4 km downslope. Sulphur dioxide emission was high at 1,065 tonnes/day. The alert level remains at 3, and Phivolcs warns that ‘Since an increasing trend is noticeable at present, the possibility of hazardous volcanic eruption is high’.''
