Situation on Mayon / Philippines in Level 3 alert.

The situation is gradually changing on Mayon volcano, located on the island of Luzon in the Philippine archipelago.

Since two months, the volcano presented short inflationary phases, suggesting a pulsing climb of magma. In August, the SO₂ levels were measured up ... raising the alert level to 2 by the Phivolcs, accompanied by a 6-km exclusion area.

The alert was raised to 3 (of 5) on September 15, following the increase of seismicity and incandescent rocks falling on the upper flanks southeast. The presence of low-frequency earthquakes indicate rising magma in the volcano, the recent observation of a lava dome and its partial collapse generating drops of incandescent rocks visible at night.
 

The exclusion zone is 6 km around the summit, and extended to 7 km to the southeast area, the most exposed to possible pyroclastic flows.

The evacuation of residents from the danger zone is underway ... they are being targeting 10,000 families who live there.
