MANILA, Philippines — The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded 185 rockfall occasions and 18 volcanic earthquakes in Mayon Volcano over the previous 24 hours.
Two pyroclastic density currents (PDC) had been additionally reported, the company added.
“Rockfall and PDCs generated by collapses of the lava move margins in addition to of the summit dome deposited particles nonetheless inside 4 (4) kilometers of the crater,” Phivolcs stated on Thursday.
Moreover the dual turbulence, the company detected a 2,252-ton sulfur dioxide emission from the volcano on Wednesday.
Furthermore, the effusion of lava from the summit crater stays “gradual” because it continues to achieve the established lava flows on the Bonga (southeastern), Mi-isi (south), and Basud (japanese) gullies that are about 3.4 kilometers, 2.8 kilometers, and 1.1 kilometers from the crater.
Alert stage 3 stays at Mayon Volcano, which means a “comparatively excessive stage of unrest and dangerous eruption” may occur inside days or perhaps weeks.
Phivolcs really helpful steady evacuation from the 6-kilometer-radius Everlasting Hazard Zone to stay protected from PDCs, rock falls, lava flows, and different volcanic hazards.
“Elevated vigilance in opposition to PDCs, lahars, and sediment-laden streamflows alongside channels draining the edifice can also be suggested. Heavy rainfall may generate channel-confined lahars and sediment-laden streamflows in channels the place PDC deposits had been emplaced,” it added.
