The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded at least four earthquakes within the vicinity of Mayon Volcano during a 24-monitoring.
“Mayon Volcano’s monitoring network recorded four volcanic earthquakes during the 24-hour observation period,” the agency said in a statement.
Phivolcs has placed the area under Alert 1 status, which means sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within the area.
The agency also observed “moderate emission of white steam-laden plumes that crept downslope” on the volcano, and said residents near the volcano be vigilant.
“Although this means that presently no magmatic eruption is imminent, it is strongly advised that the public refrain from entering the 6-kilometer radius Permanent Danger Zone (PDZ) due to the perennial life-threatening dangers of rockfalls, landslides/avalanches at the middle to upper slope, sudden ash puffs and steam-driven or phreatic eruptions from the summit,” Phivolcs said.
Phivolcs earlier said it recorded quakes in the area of Taal Volcano on Saturday and raised Alert 1 status in the area. Also, five separate quakes were recorded in Batangas, Mindoro Occidental, Davao Occidental and Quezon province on Saturday.
Netizens also said there were earthquakes in parts of Central Luzon. SOVEREIGNPH
