State volcanologists observed an increase in the frequency of pyroclastic density currents from MayonVolcano in Albay, which started late Sunday afternoon, July 9.
MANILA, Philippines – State volcanologists observed an increase in the frequency of pyroclastic density currents fromPDCs are made up of fragmented volcanic particles, gases, and ash that travel down volcanic slopes at high speeds.
The Philippine Institute of Volcanology and Seismology said in an advisory at 8 am on Monday, July 10, that there have been 33 PDCs since 5 pm, Sunday. These PDCs were “generated by dome collapse from Mayon Volcano’s summit crater and the collapsing front and margins of the advancing lava flows on the upper to middle slopes.”
“The PDCs traveled for approximately 1 to 4 minutes down the Mi-isi and Bonga gullies within 3.3 kilometers of the crater,” added Phivolcs., “but that an increase in the frequency of PDCs is being closely monitored.”remain evacuated and that communities within the 7- and 8-kilometer radius be prepared in case current PDC activity worsens,” Phivolcs said.
Alert Level 3 was raised last June 8, with Mayon showing an “increased tendency towards a hazardous eruption.”Meanwhile, sulfur dioxide emission “has only been slightly above background for the past three days and remains much lower than the typical ranges of eruption gas flux from Mayon,” Phivolcs said.Phivolcs also said there have been 109 weak low-frequency volcanic earthquakes since 5 am, Monday, “but seismic energy release has been sustained at generally the same level” since June 15.
