SORSOGON, Philippines— The Philippine Institute of Volcanology and Seismology (Phivolcs) on Sunday (May 5) raised Alert Level 1 over Mount Bulusan due to increased seismic activity.
From May 4 to 5, Phivolcs has recorded a total of 16 volcanic earthquakes, according to the agency’s Bulusan Volcano Bulletin on Sunday.
It also noted the active volcano’s tilt data from April 29 to May 5 which indicated a slight inflation in the upper slopes.
The agency also observed increase in water temperature of nearby hot springs.
Phivolcs said that raising Alert Level 1 or abnormal status “indicates that hydrothermal processes may be underway beneath the volcano that may lead to steam-driven eruption.”
With increase volcanic activity, the agency reminds residents and local government units (LGU) near the volcano to avoid entry into the 4-kilometer Permanent Danger Zone (PDZ) around the volcano.
The agency also urges vigilance in the Extended Danger Zone or areas two kilometers beyond the PDZ, “due to the possibilities of sudden and hazardous phreatic eruptions (steam but no lava), rockfall and landslide.”
Likewise, aircraft pilots are advised to avoid flying near the volcano’s summit because ash from an eruption is hazardous. – Marje Pelayo
According to PHIVOLCS-DOST, they have recorded 98 volcanic tremors in the past 24 hours having durations of five to 12 minutes.
The Agency also monitored an increase in acidity and temperature of the Taal Volcano’s Main Crater Lake.
Alert Level 1 (Abnormal) remains in effect with possibility of sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall and lethal expulsions of volcanic gas occurring and threatening areas within the Taal Volcano Island.
PHIVOLCS-DOST strongly advised everyone against entering the Taal Volcano Island, Taal Volcano Permanent Danger Zone (PDZ), especially its Main Crater Lake and fissures in Daang Kastila, due to the danger posed by the volcano’s recent activities. MNP / Raymund David
MANILA, Philippines – Pinawi ng Philippine Institute of Volcanology and Seismology (Phivolcs) ang pangamba hinggil sa muling pagsabog ng bulkang Taal kasunod ng magnitude 6.3 na lindol na yumanig sa Calatagan, Batangas pasado alas-7 Biyernes ng umaga.
Ayon kay PHIVOLCS director, Undersecretary Renato Solidum, maliit ang posibilidad na magkaroon ng epekto sa bulkan ang malakas na lindol bagaman patuloy pa nila itong inoobserbahan.
Binigyang-diin rin ni Solidum na sumabog na ang bulkan ngayong taon at malalim ang naramdamang lindol kaninang umaga.
“Siguro pagdating doon sa fault baka wala, kasi hindi naman ito ganoon kalaki at malalim siya masyado. Pero pagdating sa Taal Volcano, kasi katatapos lang ng kanyang eruption, oobserbahan natin kung may epekto talaga ito,” ang pahayag ni Solidum.
“Titingnan natin kung magre-react ang Taal Volcano, pero dapat nating maaalala, matandaan, na nasa alert level 1 pa lang naman siya,” dagdag pa niya.
Magugunitang noong buwan ng Enero 2020 ay itinaas sa alert level 4 ang Taal matapos itong magbuga ng abo.
Sa ngayon ay nasa alert level 1 ang bulkan na ang ibig sabihin ay bahagyang pagtaas ng volcanic activity gaya ng gas o steam emission at mga pagyanig. Ipinagbabawal din ang pagpasok sa permanent danger zone ng bulkan.
Paliwanag ng ahensiya, gumalaw ang Manila trench kaya’t naramdaman ang pagyanig sa Metro Manila.
Tiniyak din ng PHIVOLCS na walang direktang epekto ang lindol sa Batangas sa West Valley Fault.
Bukod sa Metro Manila, Batangas at Laguna, naramdaman rin ang lindol sa ilang bahagi ng Rizal at Northern Luzon.
