Mount Pinatubo seems to be acting up as the Philippine Institute of Volcanology and Seismology (Phivolcs) recorded some seismic activity and emission on Tuesday.
“The Pinatubo Volcano Network recorded seismic and infrasound signals of a weak explosion at Mount Pinatubo between 12:09 pm and 12:13 pm,” Phivolcs said.
“The seismic and infrasound signals are not typical of known volcanic processes and are currently being evaluated together with other potential sources,” it added.
The agency said it is advising the public to stay away from Mount Pinatubo and its surrounding areas, especially the crater area.
The last bulletin issued by Phivolcs on Mount Pinatubo was on August 12, 2021 where it lowered the Alert Level over the volcano from “1” to “zero.”
“Since 1 July 2021, there has been a continued decline in earthquake activity and a return to baseline seismic parameters in Pinatubo Volcano. A total of 104 volcanic earthquakes or an average of 2-3 events/day having magnitudes of ML0.8 to ML1.3 was recorded by the Pinatubo Volcano Network from 1 July to 11 August 2021,” it said.
“This is a significant decrease compared to the period from 28 January to 30 June 2021 when earthquake activity averaged 12-13 events/day and ranged in strength from ML 0.7 to ML3.2,” Phivolcs added.
Mount Pinatubo is one of the five active volcanoes in the Philippines monitored by Phivolcs. The others are Taal, Mayon, Kanlaon and Bulusan.
