The Philippine Institute of Volcanology and Seismology (Phivolcs), however, has maintained Alert Level 4 over the restive volcano, which means a hazardous explosion is still imminent. In its December 31 bulletin, the Phivolcs said lava was still flowing out of the volcano's crater and the rolling down of incandescent lava fragments along the Bonga gully continued. "No ash explosion was observed during times of good visibility. Emission of very weak...

PHIVOLCS-DOST reiterates that the Extended Danger Zone (EDZ) from the summit of 8-km on the southern sector of the volcano and 7-km on the northern sector should be free from human activity. Areas just outside of this EDZ should prepare for evacuation in the event hazardous eruptions intensify. Active river channels and those perennially identified as lahar prone in the southern sector should also be avoided especially during bad weather conditions or when there is heavy and prolonged rainfall.

"Yes. It is possible because the rate of changing from moderate-sized explosion, as we observed yesterday (Tuesday), is quite fast," Phivolcs chief Renato Solidum told ANC's News@8 when asked if the hazardous explosion may occur this week. Solidum, however, clarified that the Mayon Volcano may still calm down or settle with moderate eruptions during the week.

Or maybe the planet has to destroy itself to save itself. Or something. Anyway, off in the Philippines, Mount Mayon volcano has had a total of 248 volcanic quakes and tremors since Monday.
