Philippines raises alert level at volcano southeast of Manila
MANILA, Oct. 25 (Xinhua) -- The Philippine Institute of Volcanology and Seismology on Wednesday afternoon raised the alert level over Bulusan volcano in Sorsogon province, southeast of Manila, from zero to 1 after it has recorded 121 volcanic earthquakes since Oct. 14. "It means that the volcano is currently in a state of low-level unrest," the institute said in an advisory. Of the 121 volcanic earthquake.....»»
Mt. Bulusan under Alert Level 1
The Philippine Institute of Volcanology and Seismology has raised the unrest status of Bulusan Volcano in Sorsogon province from Alert Level 0 or normal status to Alert Level 1 or low-level unrest after exhibiting a series of volcanic earthquakes. In its volcanic bulletin, Phivolcs said the Bulusan Volcano Network has recorded 121 volcanic earthquakes since 14 October, 37 of which were volcano-tectonic tremors that are associated with rock fracturing processes at depths of 1-9 kilometers beneath the northwestern and southern slopes of the volcano edifice. Phivolcs also observed ground deformation and inflation or swelling of the Bulusan’s southern flank since February and the northeastern flank has been swelling since September. Bulusan also logged an increase in the volcanic carbon dioxide concentration from June to August and the spring temperature also increased since February. The post Mt. Bulusan under Alert Level 1 appeared first on Daily Tribune......»»
Philvolcs raises Mt. Bulusan alert status
The Philippine Institute of Volcanology and Seismology has raised the unrest status of Bulusan Volcano in Sorsogon province from Alert Level 0 (normal) to Alert Level 1 (low-level unrest) following a series of volcanic earthquakes. In its volcanic bulletin, Phivolcs said the Bulusan Volcano Network has recorded 121 volcanic earthquakes since 14 October, 37 of which were volcano-tectonic tremors that are associated with rock fracturing processes at depths of 1-9 kilometers beneath the northwestern and southern slopes of the volcano edifice. Phivolcs has also observed ground deformation and inflation or swelling of the Bulusan’s southern flank since February, and the northeastern flank has been swelling since September. Bulusan also logged an increase in the volcanic carbon dioxide concentration from June to August, and the spring temperature also increased since February. Phivolcs said these volcanic activities indicate that hydrothermal activity driven by deep-seated magma degassing may be occurring beneath the volcano and may lead to steam-driven eruptions at any of its summit vents. It said that Mt. Bulusan is currently in a state of low-level unrest. Hence, Phivolcs warned the public that entering int 4-km radius permanent danger zone should be prohibited and vigilance in the 2-km extended danger zone in the southeast sector must be exercised due to the increased possibility of sudden and hazardous phreatic eruptions from the summit crater and/or lateral vents. Flying close to the volcano’s summit is not allowed as ash from sudden phreatic eruptions can be hazardous to aircraft. People living within valleys and along river or stream channels, especially on the southeast, southwest and northwest sectors of the volcano, should be vigilant against sediment-laden stream flows and lahar in the event of heavy and prolonged rainfall should a phreatic eruption occur.

Phivolcs: Bulusan logs increased seismic activity
The Philippine Institute of Volcanology and Seismology has observed increased seismic activity in Bulusan Volcano in Sorsogon province. Phivols has recorded 87 volcanic earthquakes in the Bulusan Volcano Network since 5 a.m. on 14 October. Of the number, 29 were volcano-tectonic or VT earthquakes—associated with rock fracturing processes occurring 1 to 8 kilometers beneath the southern and western sectors of Bulusan Volcano. The degassing at the active summit crater and vents has been weak to moderate this week. Bulusan emitted an average of 241 tons of volcanic sulfur dioxide (SO2) gas daily on 19 October. Phivolcs also noted an increase in volcanic carbon dioxide concentrations from June to August 2023. The volcanic spring temperature has likewise increased since February. It was detected in a monitored spring on the southwestern sector of the edifice. Phivolcs said these parameters indicate that hydrothermal activity driven by deep magma degassing may be occurring beneath the volcano and may lead to steam-driven eruptions at any of the summit vents. Bulusan remains under Alert Level 0 (normal). However, increased chances of steam-driven or phreatic eruptions occurring at the crater or summit area is still expected. Entering into the 4-kilometer radius Permanent Danger Zone, particularly near the vents on the south-southeastern slopes, should be avoided due to the possibility of sudden and hazardous steam-driven or phreatic eruption, rockfall, and landslide. Flying close to the volcano’s summit should also be avoided as ash from any sudden phreatic eruption can be hazardous to aircraft. Phivolcs also warned people living within valleys and along river or stream channels should be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall.

Bulusan acting up anew — Phivolcs
The Philippine Institute of Volcanology and Seismology, or Phivolcs, on Monday warned of increased chances of steam-driven or phreatic eruptions occurring at the crater or summit of Bulusan Volcano in Sorsogon province. Phivolcs said it has recorded 87 volcanic earthquakes in the Bulusan Volcano Network since 5 a.m. on 14 October, of which 29 were volcano-tectonic earthquakes. The agency also observed weak to moderate degassing at the active summit crater and vents this week. Bulusan has emitted an average of 241 tons of volcanic sulfur dioxide (SO2) gas daily since 19 October. Phivolcs also noted an increase in volcanic carbon dioxide concentrations from June to August 2023, and an increase in volcanic spring temperatures since February. Phivolcs said these parameters indicate that hydrothermal activity driven by deep magma degassing may be occurring beneath the volcano and may lead to steam-driven eruptions at any of the summit vents. However, Bulusan remains under Alert Level 0 (normal) although Phivolcs reminded the public that increased chances of steam-driven or phreatic eruptions occurring at the crater or summit area are still expected. Phivolcs has warned the public against entering the four-kilometer-radius permanent danger zone, particularly near the vents on the south-southeastern slopes due to the possibility of sudden and hazardous steam-driven or phreatic eruptions, rockfalls and landslides. Flying close to the volcano’s summit should also be avoided as ash from a sudden phreatic eruption can be hazardous to aircraft.
