LOOK: Time-lapse footage of pyroclastic density currents (PDC) generated by lava dome collapse from the summit of Mayon Volcano at 01:16 PM and 04:09 PM, respectively. A total of 16 discrete PDC events were recorded between 12:26 PM and 04:30 PM today, 07 January 2026. The PDCs generated grayish to brownish co-PDC ash clouds that rose 200 meters before drifting east-northeast. Alert Level 3 prevails over Mayon and entry into the 6-km Permanent Danger Zone must be prohibited. #MayonVolcano | Phil

LOOK: Time-lapse video of a pyroclastic density current (PDC) being generated by lava dome collapse from the summit of Mayon Volcano at 11:18 PM on 15 June 2023, taken by the Paulog, Ligao Observation Station (VMLI) IP camera. The PDC event lasted 6 minutes based on the seismic record; Mayon's edifice was largely obscured. This was the largest PDC recorded so far since the first generated on 8 June 2023. #MayonVolcano | Philippine Institute of Volcanology and Seismology (PHIVOLCS-DOST)

NEW MAYON LAVA DOME Phivolcs reported the formation of a new dark lava dome at mayon volcano's crater after pyroclastic density currents perristed. 🎥: Joseph Trilles of DOT Region V #volcano | Baguio Herald Express

Digging into the #archives today, for this 2006 video of #lava dome growth at #MountStHelens. The #timelapse was taken during the 2004-2008 #eruption by "Brutus", a remote camera east of the #vent. The lava is a crystal-rich #dacite. It was cooling as it made its way to the surface, emerging as a series of lava spines that alternately rose and crumbled. In 2006, when this timelapse was taken, lava was erupting at a rate of about 1 cubic yard per second. The eruption ended in January 2008. At tha
