Critical alert as Philippines volcano fears grow for ‘possible eruption in weeks or even days’

Thousands of people have been forced into emergency shelters by an active volcano in the Philippines, with warnings a “hazardous eruption” could happen in days.
 
Officials raised the alert level around Mount Mayon in Albay province to critical after it spewed ash thousands of metres into the air and magma could be seen glowing in the crater.
 
The first “steam-driven eruption” started at around 5pm local time on 13 January, with the Philippine Institute of Volcanology and Seismology recording an ash column 2,500 meters high.
 
Two further eruptions have since been recorded, with villagers reporting a sulphurous smell and rumbling sound.
 
In a statement, the institute said: “Mayon is exhibiting relatively high levels of unrest and that magma is at the crater and that a hazardous eruption is possible within weeks or even days.”
 
Residents have been urged to protect against inhaling the ash by wearing masks or covering their noses and mouths with damp cloths.
 
Given the increasing danger, officials have recommended that a “danger zone” of a 7km radius be enforced “due to the danger of rockfalls, landslides and sudden explosions or dome collapses that may generate hazardous volcanic flows”.
 
Deadly cold lava flows or “lahars” may also be triggered.
 
People living outside the danger zone have been warned to take precautions against potential roof collapses due to the weight of ash and rainfall.
 
Mayon last erupted in 2014, with lava flows forcing thousands of people to evacuate.
 
It was most deadly in February 1841, when 1,200 people were killed and lava buried a town.
 
Experts say it has been displaying abnormal behaviour since late last year.

New flank eruption reported at Erta Ale volcano in Ethiopia

News have come in about a fissure eruption at the SE flank of the volcano, approx. 7 km distance from the summit caldera and its lava lake (which partially collapsed on and after 20 Jan). 
 
According to our local correspondents, the activity at the summit has decreased a lot, which would be in accordance with the scenario of lava now being drained through lower fissures on the flanks. Apparently, the fissures opened on or shortly after 21 Jan and produce large amounts of lava now flowing into the direction of Afdera.

Relatively intense activity at Stromboli volcano Eolian Islands in Italy

The activity at the “Lighthouse of the Mediterranean” has been much more intense recently than during most of the year. 
 
Explosions mainly from the eastern vent (towards Stromboli village) have been observed at intervals of approx. 10 minutes, ejecting dense jets of incandescent lava to up to estimated 150 m height. 
 
Continuous glow can be seen from adjacent vents in the central crater area as well, suggesting a relatively high lava column inside the conduit.

Intense activity continues, possible lava flows outside the caldera at Erta Ale volcano in Ethiopia

Activity remains elevated at the volcano in the Danakil. The latest available information show simultaneous effusive activity from both the north and the south crater – the latter, which contained the famous lava lake has been overflowing and building a new lava shield that started to partially fill the summit caldera. 
 
It seems that lava flows have started to overflow even outside the caldera through the low part of the rim on the NE side (judging from satellite data).
