PINATUBO VOLCANO ADVISORY 30 November 2021 4:00 PM

This serves as an advisory of an explosion signal recorded at Pinatubo Volcano.

The Pinatubo Volcano Network recorded seismic and infrasound signals of a weak explosion at Mt. Pinatubo between 12:09 PM and 12:13PM. The event produced a plume that was detected by the Himawari-8 Satellite and reported to DOST-PHIVOLCS by the Tokyo Volcanic Ash Advisory Center. The seismic and infrasound signals are not typical of known volcanic processes and are currently being evaluated together with other potential sources, e.g. aircraft activity, ordinance disposal, and others. In addition, there has been very low seismic activity in the past days and geochemical survey of the Pinatubo Crater Lake this November 2021 yielded low diffuse volcanic CO2 flux (257 tonnes/day), discounting magmatic activity beneath the edifice.

DOST-PHIVOLCS is cautioning the public to refrain from venturing in the vicinities of Pinatubo Volcano at this time. Local government units are advised to prohibit entry into Pinatubo Crater until the source of the above explosion event has been determined and to report to us any related information. Communities and local government units surrounding Pinatubo are reminded to be always prepared for both earthquake and volcanic hazards and to review, prepare and strengthen their contingency, emergency and other disaster preparedness plans. DOST-PHIVOLCS continues to strengthen its monitoring of the volcano with ongoing upgrades to the PVN (Pinatubo Volcano Network), periodic geochemical surveys of the Pinatubo Crater lake and GPS and satellite analysis of ground deformation. DOST-PHIVOLCS is closely monitoring the volcano’s condition and any new development will be relayed to all concerned.
