Volcanic activity worldwide 30 Jul 2015: Piton de la Fournaise volcano
Thursday Jul 30, 2015 21:00 PM | Piton de la Fournaise (La Réunion)
: A new eruption might be under way at the volcano. Since last weekend, seismic activity from a source at 1-2 km depth beneath Dolomieu crater has been increasing. In addition, increased degassing and inflation of the Dolomieu crater have been detected, both likely signs of a new magma intrusion at shallow depth.
The prefecture has closed access to the Enclos. Whether an eruption will occur or not remains to be seen in the coming hours or days. If it does, it would be the third eruption of Piton de la Fournaise in 2015 after the ones in February and May.
Already on 6 July, a similar seismic swarm occurred, but was not followed by an eruption. More than 90 quakes within one hour triggered an eruption alert and the Enclos was closed to the public. The caldera was reopened (with some limitations) on 9 July.

Sinabung (Sumatra, Indonesia)
: (27 Jul
) Activity has remained essentially unchanged. Effusion of viscous lava continues at slow pace to feed the lava dome with two active lobes on the SE and E upper flanks. At 12:22 local time today, a small part of the eastern lobe collapsed into a medium-sized pyroclastic flow that traveled approx. 2.5 km towards the outskirts of the (already evacuated and destroyed) villages of Bekerah and Simacem. ...
