In an advisory issued at 1 a.m. Monday (June 27), the Philippine Institute of Volcanology and Seismology (PHIVOLCS) has warned local officials and residents near the southwestern slopes of Mount Bulusan in Irosin, Sorsogon of lahar flow and sediment-laden stream flows triggered by heavy rainfall.
On Sunday night, the Philippine Atmospheric,Geophysical and Astronomical Services Administration (PAGASA) in Southern Luzon issued a thunderstorm advisory in six provinces of the Bicol region.
PHIVOLCS said that it began monitoring small volumes of lahar flow at 7:04 p.m. on Sunday after a rain that lasted for about 54 minutes, through a seismic and infrasound stations of the Bulusan Volcano Network, along Calang Creek in Barangay Cogon.
Mount Bulusan remains to be under Alert Level 1, with seven recorded earthquakes for the past 24 hours, which means entry into four kilometer-radius Permanent Danger Zone and entry without vigilance into the Extended Danger Zone is not allowed, as well as any aircraft flying close to the volcano.
Meanwhile, Pagasa said that a low pressure area (LPA) monitored 100 kilometers east of Daet, Camarines Norte will induce overcast skies and scattered rains over some parts of Luzon and the Visayas.
“Ngayong araw, dahil sa LPA, malaking bahagi ng ating bansa ay inaasahan natin na may mga pag-ulan,” said Aldczar Aurelio, Pagasa’s weather specialist. However, the agency doesn’t think that the LPA will progress into a storm within the next 24 to 48 hours.
(Today, because of the LPA, large parts of our country will experience rain.)
“Dahil sa LPA, ang buong Kabisayaan, inaasahan natin ang maulap na kalangitan na may kalat-kalat na pag-ulan at thunderstorms,” Aurelio added.
(Because of the LPA, the whole of Visayas is expected to experience isolated rains and thunderstorms.)
Meanwhile, PHIVOLCS has also warned communities surrounding Mount Bulusan that another lahar and other sediment-laden stream flows could still happen especially during heavy rainfall.
