Mayon continues to emit pyroclastic density current

MANILA, Philippines — Mayon Volcano in Albay continued to generate another pyroclastic density current, or “uson,” marking its 189th consecutive day of occurrence on Monday, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

In a Facebook post, Phivolcs said the “uson,” which was caused by a prevailing effusive eruption, was recorded between 6:31 a.m. and 6:46 a.m.

State seismologists noted that the effusive eruption triggered incandescent lava flows and rockfalls on Monday.

Pyroclastic density currents are fast-moving mixtures of ash, hot gases, and fragmented volcanic particles that happen during an eruption.

Meanwhile, the surge in sulfur dioxide emissions increased the chance of a more powerful eruption, Phivolcs announced on Saturday.
