WATCH: Mayon Volcano strombolian activity on 95th day of effusive eruption

Mayon Volcano had minor strombolian activity on Friday night and on Saturday, the Philippine Institute of Volcanology and Seismology said.

The events at the summit crater were captured on video by the Mayon Volcano Observatory Raspberry Pi camera. 

PHIVOLCS said the events happened at 10:40 p.m. on Friday, April 10, and at 12:38 a.m. on Saturday, April 11.

"The 10:40 p.m. event generated an ash plume that rose approximately 700 meters above the crater before drifting westward and was also audible at the observatory," it said.

Another minor strombolian activity was recorded at 12:45 p.m. on Saturday. Short-lived lava fountaining was also observed at 6:46 a.m. 

"These events generated ash plumes that rose 600 meters above the crater before drifting southwest," PHIVOLCS said. 

According to the United States National Park Service (NPS), strombolian eruptions are moderately explosive eruptions that come with balsatic magma and moderate gas content.

Such eruptions are often characterized with “intermittent, discrete explosive bursts” that ejected pyroclasts in “firework-like incandescent rooster-tails.”

Saturday marks the 95th consecutive day of Mayon Volcano's effusive eruption.

The volcano also produced incandescent lava flows, pyroclastic density currents (PDC) or locally known as “uson,” and frequent rockfalls. 

PHIVOLCS said Alert Level 3 remains in effect.

"Entry into the 6-km Permanent Danger Zone is strictly prohibited," it added. —with Jiselle Anne Casucian/KG/VBL, GMA News
