Phivolcs lowers Mayon status to Alert Level 1

MANILA, PHILIPPINES – According to a statement released by the PHIVOLCS on Tuesday, the alert status of Mayon Volcano has been reduced from Level 2 (moderate level unrest) to Level 1 (low-level unrest).

During their bulletin at 5:30 p.m., the Phivolcs reported that they had witnessed a consistent decrease in the metrics being tracked.

Since the beginning of the year, the volcano has produced an average of two to three daily earthquakes, most of which were associated with rock fracture reactions.

The rate of lava growth was also observed to have significantly slowed down, with an average of zero to one rockfall occurring daily.



During the period beginning in January, it was noted that the daily average of sulfur dioxide (S02) emissions was 1,148 tons.

On January 22, 2019, the S02 flux was at its maximum point of 2,394 tons, while on Tuesday, it was at its lowest point of 420 tons.

This year, Phivolcs reported seeing degassing plumes ranging from weak to moderate intensity.

On the other hand, it stated that the reduction in the Mayon’s alert status “should not be interpreted that unrest has completely ceased.”



Due to the ever-present dangers of rockfalls, avalanches, and abrupt steam-driven or phreatic eruptions at the summit area, participation in the six-kilometer permanent danger zone still needs to be permitted.

Because ash from any unexpected eruption can harm aircraft, aviation authorities are strongly encouraged to caution pilots to avoid flying close to the volcano’s summit.
