Phivolcs continuing to monitor Mayon after ‘dark lava spines’ found in summit
The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded six rockfall events at Mayon Volcano in a 24-hour period, with no volcanic earthquakes detected.
A weak crater glow was also observed, visible only through a telescope, and new spines of dark lava were noted from its summit lava dome last week.
Mayon Volcano is emitting an average of 307 tonnes of sulfur dioxide per day.
Phivolcs maintained Alert Level 1 for Mayon Volcano, indicating low-level activity, and stated there is no immediate threat of an eruption in the coming days.
The expansion of a no-fly zone is being considered by the Civil Aviation Authority of the Philippines (CAAP) based on Phivolcs' scientific inputs regarding potential volcanic hazards.
