Mayon within the Philippines hasn’t erupted since 2014, however it seems that it’s waking up from its temporary slumber. PHIVOLCS raised the alert standing at Mayon to Degree three (on a scale of Zero-5) after a weekend of steam-driven (phreatic) eruptions and tons of of earthquakes. This modification in alert stage got here with a compulsory evacuation of individuals residing inside six kilometers of the volcano and 7 kilometers from the southern facet due to the potential for rock falls and pyroclastic flows. Colleges within the space have additionally closed because of the new eruptive exercise. The newest PHIVOLCS report additionally mentions sturdy glow was noticed on the summit crater and a brand new summit dome and small lava circulation on the southeast flanks.
UPDATE 1/15/2018 eight:00 AM: PHIVOLCS launched an image that reveals the lengthy lava circulation and glowing rockfalls on the flanks of Mayon (see under). Over 9,000 individuals have been evacuated from the world close to the volcano up to now and extra may come if the eruption worsens. Some flights have been canceled as effectively because of the exercise at Mayon. PHIVOLCS additionally maintains a webcam pointed at Mayon, though the climate makes it troublesome to see a lot of the volcano proper now.

Mayon is an particularly hazardous volcano as over 250,000 individuals stay inside 10 kilometers of the volcano. In fact, solely final week a variety of items of monitoring gear have been stolen from Mayon. Lava flows are frequent at Mayon, however so are extra explosive eruptions and pyroclastic flows, so there are a large number of hazards that might influence the world. Add to that the specter of volcanic mudflows (lahars) that might happen if it rains after/throughout an eruption. In fact, solely final week some gear wanted to observe the volcano was stolen. This makes it tougher for volcanologists to maintain monitor of issues like earthquakes and deformation on the conical volcano.
Elsewhere, the eruption of Kadovar in Papua New Guinea, which began final weekend, continues as effectively. Seven hundred individuals have been evacuated to the mainland as far as new explosions and a lava dome have been seen on the island volcano. PNG officers have additionally ordered the evacuation of Bam for fears for volcanic eruptions on that island solely 12 kilometers from Kadovar. Nevertheless, it’s unclear if there are any indicators that Bam may erupt for the primary time since 1960 or if officers are extra involved with the specter of tsunami generated by Kadovar. Blup Blup, one other close by island, may even see its 2,000 residents evacuated. The plumes of steam and ash have reached a number of thousand ft, which nonetheless stays a menace to supply a bigger explosive eruption or pyroclastic flows that might run into the ocean.
New footage of Kadovar present the tall, dark-gray plumes from the erupting crater and far of the island has been stripped naked by the rockfalls, pyroclastic flows and ash fall. Oddly, officers have seen discoloration of the water close to Kadovar, which may counsel that there is perhaps submarine eruption occurring, though it might be from materials from the island eruption assembly the ocean across the island. This occurred throughout a interval of unrest close to Kadovar on 1976, so it is perhaps associated to modifications within the hydrothermal system for the volcano.
Lastly, Agung in Indonesia seems to be like it’s nonetheless on the cycle of explosions. On January 12, the volcano produced a brand new blast that reached 2.5 kilometers (eight,200 ft) and despatched ash throughout the world. Greater than 50,000 persons are nonetheless evacuated from the world close to Agung.
