The volcano has been becoming increasingly restless during the past days, which makes the likelihood of a new eruption now larger than the chance that no eruption occurs, according to Indonesian volcanologists.
Recent seismic activity at Agung
New cracks and warm areas in the crater have been detected on satellite imagery and the level of degassing has also increased, now often creating a plume of 50-200 m above the volcano. Inflation and ongoing seismic activity also remain elevated.
A felt magnitude 4.2 quake occurred at 5 km depth under the northwestern flank on Tuesday, suggesting shallow magma movements are taking place.
Still, it is impossible to predict whether this crisis will actually lead to an eruption in the near future, and if so, when and how large an eruption will occur. At any rate, it could occur now any time and people in the vicinity should be on alert.
According to news articles, more than 150,000 people have so far been evacuated from areas within 12 km radius of the volcano and authorities are very busy disseminating information and preparing for the possible eruption, including installing warning sirens in some of the densest populated places.
Tourists visiting Bali should take an increased likelihood into account that flights could be diverted or canceled in case of significant ash emission (which is likely if Agung erupts).
