MANILA (Philippine Daily Inquirer/Asia News Network): State seismologists on Monday (July 10) said Mayon Volcano saw an uptick in volcanic earthquakes totalling 109 in 24 hours.
The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded the number of volcanic tremors between 5:00am on July 9 and 5:00am on July 10.
The most recent volcanic earthquakes were more than the 26 reported during the previous period.
A total of 325 rockfall events and 943 metric tonnes of sulfur dioxide flux were also reported in the latest period.
Also, during the same period, 19 dome collapse pyroclastic density currents (PDC) lasted from one to three minutes, while four lava front collapse PDCs and one lava collapse PDCs were also recorded.
PDC refers to mixtures of fragmented volcanic particles, hot gases, and ash that rush down the volcanic slopes or rapidly outward from a source vent at high speeds.
Mayon Volcano has been under Alert Level 3 since June 8, with the unrest seen to last for a few months based on the volcano monitor’s observations.
