Roundup of Global Volcanic Activity
Piton de la Fournaise (La Réunion): A new eruption has started at the volcano, following a brief seismic crisis that started early this morning.
According to OVPF, the new (fissure) vent should be located between Bory, Dolomieu and Rivals craters on the upper flank of the Dolomieu main cone. A lava flow is descending SSW and has already reached the base of the Dolomieu crater, i.e. the floor of the enclos. Its length is more than 1 km.
Karangetang (Siau Island, Sangihe Islands, Indonesia): Since 10 Jan 2015, the volcano has been active again. A lava dome is growing at the summit, producing incandescent avalanches.
Our correspondent Andi who visited the volcano during the pst days wrote: "Mt Karangetang spews lava flows and the status has been raised again into level 3. According to the seismic recordings from the observatory post, there are harmonic tremor and volcanic quakes, indicating the ongoing dome building. A warning was issued to the local population to prepare for possible evacuations."
