Mayon’s 24-hour rampage: 5 volcanic earthquakes, 361 rockfalls unleashed
MANILA, Philippines — State seismologists on Friday said Mayon registered five volcanic earthquakes and 361 rockfall events from 5:00 a.m., July 13 to 5:00 a.m. July 14.
The Philippine Institute of Volcanology and Seismology (Phivolcs) also said in its latest bulletin that the volcano had seven pyroclastic density currents (PDC) generated by a dome and lava-front collapse during their last 24-hour monitoring.
PDC refers to mixtures of fragmented volcanic particles, hot gases, and ash that rush down the volcano’s slopes or rapidly outward from a source vent at high speeds.
The previous 24-hour observation period showed that it logged 10 PDC, three volcanic earthquakes, and 286 rockfall events.
Phivolcs has raised Mayon Volcano’s alert level to 3 since June 8. Its officials also said that Mayon’s restlessness may last for several months.
