Roundup of Global Volcanic Activity
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.
