ni Lolet Abania | October 12, 2022



Itinaas ng Philippine Institute of Volcanology and Seismology (Phivolcs) sa Alert Level 1 ang Bulkang Bulusan sa Sorsogon ngayong Miyerkules.


Ayon sa Phivolcs, itinaas ang alert level ng Bulusan sa 1 mula sa 0 dahil sa kanyang “state of low-level unrest.”


Sa kanilang 3PM bulletin, sinabi ng Phivolcs na nakapag-record ang Bulusan Volcano Network ng 126 weak at shallow volcanic earthquakes simula nitong umaga ng Martes.


Anang ahensiya, naobserbahan din ang iba pang unrest parameters, kabilang na ang ground deformation, pagtaas ng volcanic carbon dioxide concentrations, at mga on-ground reports ng sulfurous odor emissions.


Sa ilalim ng Alert Level 1, pinagbabawalan ang publiko na pumasok sa Bulusan’s 4-kilometer-radius permanent danger zone (PDZ).


Dapat ding maging maingat sa pag-obserba sa 2-kilometer extended danger zone na ayon sa Phivolcs, “due to the increased possibilities of sudden and hazardous phreatic eruptions.”


“People living within valleys and along river/stream channels especially on the southeast, southwest, and northwest sector of the edifice should be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall should a phreatic eruption occur,” sabi pa ng ahensiya.
