Lahar warning up around Mayon

A drastic increase in the number of volcanic earthquakes and rockfall events in Mayon Volcano was recorded yesterday, while the state weather bureau warned of possible lahar flows and landslides due to heavy rains to be spawned by Tropical Storm Mario. The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded 142 volcanic earthquakes, far higher than the previous record of 45, and 251 rockfall events in the past 24 hours. “Our seismographs could have recorded more rockfall incidents, but the noise created by the heavy rains over Mayon had disturbed the accurate detection,” Philvocs-Bicol chief volcanologist Ed Laguerta told The STAR.
