Volcanos

Roundup of Global Volcanic Activity

Shiveluch (Kamchatka): The volcano's activity seems to have picked up a bit compared to recent weeks. A partial collapse of the active dome generated a pyroclastic flow that traveled several km to the south, accompanied by an ash plume that rose to 4-4.5 km altitude and drifted east.

Mauna Loa (Big Island, Hawai'i): Seismic unrest continues at the volcano, but at lower levels than during mid-late summer, HVO reports: "Earthquakes occurred beneath Mauna Loa's upper Southwest Rift Zone at depths less than 13 km (8 miles). Deformation data are still consistent with inflation of magma reservoirs beneath Mauna Loa's summit and upper Southwest Rift Zone."

Piton de la Fournaise (La Réunion): Another (the third) eruptive phase began at the volcano yesterday evening. From 16:00 local time, the volcano observatory recorded an increase in tremor and new lava was seen in the vent after 20:00. Shortly after 04:00 this morning, activity intensified further and formed a new active lava pond inside the large new crater that had formed early in the eruption near Piton Rivals. The activity is currently observable from the path leading to Piton Bert.
