The larger volcanic eruption of yesterday, was (according to PHILVOLC) of phreatomagmatic origin, took 8 minutes and promoted an ash cloud, which rose 5 km above the summit level. Pyroclastic flows (or pyroclastic density flows, as they are now called) have been created and flowed through various drainage channels. They reached lengths of 4 km. Volcanic ash rained down in several villages. Videos show that it got so dark that cars had to drive with light and barely had visibility. The local airport was closed and flights were canceled. This was the Mayon’s strongest eruption to date in the current eruption phase.
