This is an update on the small phreatic eruption of Mayon Volcano (13.2500°N, 123.6833°E) at 8:00 AM yesterday (May 7, 2013), which lasted 2 minutes 26 seconds. The explosion column produced was 500m high above the summit and precipitated traces of ash in the areas west-northwest of the volcano, affecting Barangays Muladbucad, Guinobatan and Nabonton, Nasisi, Basag and Tambo, Ligao City, Albay, and areas upslope of these barangays. In the past 24-hr period, two (2) minor rockfall events were detected by the Mayon seismic network. Seismic parameters remain within background levels and indicate no increase in overall volcanic activity.

PHIVOLCS still maintains Alert Level 0 over Mayon Volcano, which means that no magmatic eruption is imminent. However, small phreatic eruptions including small steam and ash explosions may occur suddenly with little or no warning. The public is strongly reminded of refraining from entry into the 6-kilometer radius Permanent Danger Zone (PDZ) due to the perennial threat of sudden steam-driven eruptions and rockfalls from the upper and middle slopes of the volcano.
