ALBAY, Philippines — Three consecutive phreatic eruptions or steam-blast eruptions were recorded by the Philippine Volcanology and Seismology or Phivolcs in Mt. Mayon this weekend.

It first spewed ash last Saturday at 4:21 p.m. that reached 2,500 feet high.

It was followed by a phreatic eruption at 8:49 yesterday morning and at 11:43 in the afternoon.

Aside from the thick ash the agency also recorded 158 rockfall events around the volcano just in the span of two days.

Due to this, from an alert level 2 the alert status of Mt. Mayon was raised to level 3.

Dr. Ed Laguerta, the resident volcanologist of Philvolcs based in Albay explained, there is a possible movement that is happening beneath the volcano.

“The eruption yesterday was an implication so now, there is a continuous rock falls because rock falls will not stop if nothing is pushing,” he said.

According to Phivolcs, there already is a crater glow on the volcano’s summit which signifies the growth of magma in the volcano’s crater.

He said it means that the volcano can possibly erupt this week.

That is why the 6-kilometer permanent danger zone around the volcano is being monitored as well as the 7-kilometer extended danger zone or EDZ.  — 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

Phivolcs monitors Mt. Mayon after minor emissions

ALBAY, Philippines – The Philippine Institute of Volcanology and Seismology (Phivolcs) is constantly monitoring the activity of Mt. Mayon following a series of minor ash emissions.

According to Senior Science Specialist Dr. Ed Laguerte, these activities cannot be equated into something alarming. It is just a result of the cooling off of magma inside the volcano following its latest eruption in January.

However, they are considered abnormal activity as far as Mt. Mayon is concerned.

“Sa geophysics kasi hindi gaano, walang masyadong ipinapakita ngayon, maliban doon sa mga gas output nito. Mga pailan-ilan tapos nagkakaroon ka ng ash emission tapos sa gas output nagrarange pa rin doon sa hindi pa rin normal kasi meron pa ngang nagdedegas na magma,” Laguerte explained.

The expert added that they have monitored a slight swelling in the upper slope of the volcano.

Still, it is not a reason to raise the current alert level 2 to level 3.

Meanwhile, Phivolcs is currently using a new equipment in monitoring volcanic activities in the country.

The agency is now using the Fourier transform infrared spectroscopy (FTIS) facility which is used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. The facility, which was bought in Germany, is also expected to generate data regarding Mt. Mayon’s other gas emissions.

As for the recent activity of Mt. Mayon, the Phivolcs has recorded around nine volcanic quakes within 24 hours and about 1,377 tons of sulfur dioxide gas have been spewed from the period of November 30 to date – Marje Pelayo (with reports from Allan Manansala)

Mayon evacuees receive relief goods from the local government


ALBAY, Philippines – A threat of lahar flow prompted more than 2,500 residents living at the foot of Mt. Mayon in the municipality of Guinobatan to rush to evacuation centers on Saturday, September 15.

Days of rain prior to the onset of Typhoon Ompong caused lahar deposits around the volcano to soften and flow with rainwater.

According to Mayor Ann Yap, lahar flow poses a great danger to residents especially those living near the river.

“Sila po ang nasa lahar-prone areas so mas mabuti po na nasa safe place sila. Nag pre-emptive evacuation na po tayo. With the recent eruption, with the lost materials, kapag malakas ang buhos ng ulan pwedeng ma-endanger ang mga constituents,” she said.

The local government assured prepositioned relief goods for evacuees.

In Catanduanes, 53 residents were evacuated from the municipalities of Viga and San Andres in line with the typhoon.

Relief goods were also distributed to affected residents.

Nagseserve na tayo sa mga evacuation centers, sa mga ibang fishermen, sa family…dahil nagbawal tayong maglayag,” said Catanduanes governor Joseph Cua.

Meanwhile, based on the latest report of the Office of the Civil Defense Region V, there are more than 1,600 stranded passengers in all nine ports across Bicol Region.  The regional government assured that they are provided with the necessary assistance while waiting for the weather to improve. – Marje Pelayo (with reports from Allan Manansala)
