Phivolcs sees rise in sulphur emissions from Kanlaon Volcano
Published on: Sunday, June 08, 2025 Published on: Sun, Jun 08, 2025 By: Inquirer Text Size: Kanlaon Volcano in a calmer state in this file photo taken by Marvin Escander, contributor. MANILA: Kanlaon Volcano registered an increase in sulphur dioxide emissions Friday, according to 24-hour monitoring by the Philippine Institute of Volcanology and Seismology (Phivolcs). The report, posted on Saturday, noted that the volcano released 5,868 tons of sulfur dioxide – significantly more than the 2,841 tons emitted the previous day. Advertisement The volcano also generated a 900-meter tall plume that drifted southward and southeastward. It also registered continuous degassing. Aside from this, four volcanic earthquakes were recorded from the volcano. Phivolcs earlier defined volcanic earthquakes as earthquakes 'generated by magmatic processes of magma-related processes beneath or near an active volcano.' The volcano, which sits between Negros Occidental and Negros Oriental, remains under Alert Level 3 or in the category of magmatic unrest. Phivolcs still prohibited flying any type of aircraft close to the volcano. It also reminded residents that possible hazards can occur such as sudden explosive eruption, lava flow, ashfall, rockfall, lahar flor during heavy rains, and pyroclastic density current. Advertisement The volcano logged a moderately explosive eruption last May 13, which lasted for five minutes. * Follow us on our official WhatsApp channel and Telegram for breaking news alerts and key updates! * Do you have access to the Daily Express e-paper and online exclusive news?

Philippines raises alert level at restive volcano after eruption
MANILA, April 28 (Reuters) - A restive volcano in the central Philippines spewed a column of ash as high as 4.5 km (2.8 miles) into the sky on Monday morning, prompting authorities to raise the alert level at Mount Bulusan and warn residents to stay out of a 4-km danger zone. The Philippine Institute of Volcanology and Seismology (Phivolcs) raised Bulusan's alert status from 0 to 1 on its five-level scale, signalling low-level volcanic unrest and warning of possible phreatic eruptions.

Prior to the eruption, which occurred between 4:36 a.m. and 5:00 a.m on Monday, the institute had recorded 53 volcanic earthquakes over a 24-hour period and local officials reported rumbling sounds. Phivolcs also urged vigilance within an extended 2-km danger zone on the volcano's southeast sector due to the risk of rocks and other debris being ejected by the volcano, as well as rock falls and avalanches. Civil aviation authorities were advised to warn pilots against flying close to Bulusan's summit. Bulusan is one of 24 active volcanoes in the Philippines. The country lies is in the Pacific "Ring of Fire," where volcanic activity and earthquakes are common.

Philippines raises alert level at active volcano after eruption sends ash 4.5km into sky
Mount Bulusan, an active volcano in central Philippines, erupted early on Monday, sending ash 4.5 km into the sky. The eruption was phreatic, or steam-driven, lasting 24 minutes from 4.36am local time, the Philippine Institute of Volcanology and Seismology (Phivolcs) confirmed. It produced a plume that reached 4.5km in height, triggering ashfall in Cogon and Bolos in Irosin, as well as in Puting Sapa, Guruyan, Buraburan, and Tulatula Sur in Juban, according to Rappler. Phivolcs raised its alert level from 0 to 1, indicating low-level volcanic unrest and the risk of phreatic eruptions. Scientists say that a phreatic eruption occurs when water beneath the earth's surface comes into contact with hot magma or rocks, causing it to rapidly turn into steam and explode. These eruptions are steam-driven, ejecting ash, gas, and debris, but do not involve new magma.

About 15 minutes prior to the eruption, local government officials reported hearing 'rumbling sounds', which were also detected by Phivolcs' infrasound sensors. Bulusan Volcano, situated in Sorsogon province, is approximately 400 km southeast of the Philippine capital, Manila, and is one of the country's most active volcanic sites. Phivolcs also urged residents to remain vigilant within an expanded 2-kilometre danger zone on the volcano's south-east flank, warning of the risk of ejected rocks, debris, rock falls and avalanches. It added that ashfall had been reported in several nearby communities. Civil aviation authorities were also instructed to alert pilots to avoid flying near Bulusan's summit, due to the potential hazards posed by volcanic ash and sudden explosive events. Phivolcs has also warned that more phreatic eruptions are possible, with potential hazards including pyroclastic density currents (PDCs), ballistic projectiles, rockfalls, avalanches, and ashfall. PDCs are 'hazardous mixtures of hot volcanic gas, ash, and fragmented rock' that travel down volcanic slopes at high speeds.
