WATCH: Mayon spews ash clouds on 91st day of effusive eruption

State volcanologists recorded minor strombolian activity or low-level explosions at the Mayon Volcano that caused ash clouds on Tuesday morning.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) said the minor strombolian activity was logged at 8:59 a.m. and 9:16 a.m.

PHIVOLCS shared close-up footage of the ash clouds spewed by Mayon Volcano, as recorded by the DOST-PHIVOLCS Quick Response Team.

Minor strombolian activity are low-level, intermittent explosions that launch lava fountains and magma fragments from the crater.

Mayon Volcano continued its effusive eruption for the 91st consecutive day on Tuesday, generating incandescent lava flows, pyroclastic density currents (PDC) or “uson,” and rockfalls.

Earlier in the day, PHIVOLCS also reported another short-lived lava fountaining at the volcano at around 8:39 a.m. and 9:23 a.m. Tuesday.

The activity produced ash clouds that rose 300 meters before drifting west-northwest, it added. 

State volcanologists reminded the public that Alert Level 3 remains in effect over Mayon Volcano and that entry into its six-kilometer permanent danger zone (PDZ) is prohibited. — JMA, GMA News
