Lava flowing from Mt. Mayon

MANILA, Philippines – The Philippine Institute of Volcanology and Seismology or PHIVOLCS said the lava coming from Mt. Mayon might soon flow to different directions.

According to the Department of Science and Technology (DOST) Undersecretary and PHIVOLCS Officer in Charge Renato Solidum, the lava coming from the now restive volcano normally flows from the southern part of its crater since the 60s until the 80s.

However, since the crack on its crater is already healing, the lava may flow from other parts.

With this, PHIVOLCS suggests to residents to completely abandon the 6-kilometer Permanent Danger Zone (PDZ).

This is because there might be an occurrence of frequent landslide and rockfall around the volcano which may hit the designated permanent danger zone.

The towns surrounding Mt. Mayon are Daraga, Camalig, Guinobatan, Ligao, Tabaco, Malilipot, Sto Domingo and Legaspi.

“There should be no houses there and just use the various ways on how to farm. But the people should stay away from those areas,” Solidum said.

However, the residents say they have no other choice but to return to their homes despite the danger the volcano poses.

“How about our livelihood? Our cows here. We know it’s prohibited. But how about our cows? We have no other place to transfer,” resident Erning Mostera said.

“When it happens, how about our livelihood?” resident Mariequeta Nemo said.

PHIVOLCS has yet to determine up to when Mt. Mayon will continue to show signs of eruption.

It can be noted that when the volcano showed signs of eruption in 2009, the evacuees were able to return to their homes only after 2 weeks to a month.

PHIVOLCS said the lava coming from Mt. Mayon is more dangerous since it’s more diluted and thus can reach farther areas. – Rey Pelayo | UNTV News & Rescue

113 tremors recorded in Taal Volcano in past 24 hours

MANILA, Philippines—The Philippine Institute of Volcanology and Seismology (Phivolcs) has recorded an increasing number of tremors in Taal Volcano this week.

Based on the agency’s report released on Friday (February 26), the state seismologists recorded 113 volcanic tremors with an average duration of 34 minutes in the past 24 hours. This is a significant jump from yesterday when 69 volcanic tremors were recorded.

Phivolcs also reported an emission of weak steam-ladden fumes from the vents of the volcano’s main crater.

Despite the increase in tremors, Taal remains at Alert Level 1. The public is advised — especially residents near Taal — to remain in a safe area as more volcanic earthquakes, steam emissions, and minor ashfall can occur. Several residents have already been evacuated last week.

Phivolcs also reiterated that entry into Taal’s permanent danger zone remains prohibited. AAC

MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (PHIVOLCS) warned the public of possible sudden steam-driven or phreatic explosions from Taal Volcano, based on their most recent recorded seismic activities of the volcano on Tuesday (February 16).

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

Pangambang sumabog ang Mt. Taal matapos ang malakas na lindol sa Batangas, pinawi ng Phivolcs

Robie de Guzman   •   December 25, 2020

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.
