A total of 47 volcanic earthquakes and multiple effusive eruptions were recorded at Mayon Volcano in Albay over the past two days, marking the 56th consecutive day of intensified unrest.

According to the Philippine Institute of Volcanology and Seismology, its 24-hour monitoring from Saturday and Sunday showed heightened seismic activity. The recent tally far exceeded the daily average of five earthquakes recorded throughout February.

PHIVOLCS said 22 earthquakes were logged on 28 February, the highest daily count for the month. The second highest was recorded on 14 February with 20 occurrences.

On 1 March, 25 volcanic quakes were documented, along with 392 rockfalls and 18 pyroclastic density current signals.

The agency also reported sulfur dioxide emissions averaging 2,256 tonnes per day. Minor strombolian activity persisted during the monitoring period.

Despite the increased activity, PHIVOLCS maintained Alert Level 3 over Mayon, indicating a relatively high level of unrest but no imminent large-scale explosive eruption based on current observations.

Entry into the six-kilometer permanent danger zone remains strictly prohibited. Aircraft have also been advised to avoid flying close to the volcano’s summit due to potential hazards.

Meanwhile, Mount Kanlaon and Taal Volcano remain under their respective alert levels.

Mount Bulusan in the Bicol region has been placed under Alert Level 0 after recent seismic activity was detected, with no signs of lava effusion forecast, according to PHIVOLCS.
