Roundup of Global Volcanic Activity

Manam (Papua New Guinea): A volcanic ash plume at estimated 7,000 ft (2.1 km) altitude extending 70 km north from the volcano was reported this morning (VAAC Darwin).

Karangetang (Siau Island, Sangihe Islands, Indonesia): The eruption continues at the volcano: it is characterized by Strombolian activity at the summit crater and lava extrusion that forms frequent incandescent avalanches.

Dukono (Halmahera): Continuous ash emissions are being observed from the volcano, generating plumes at 2-3 km altitude that drift up to 70-80 km to the east (Darwin VAAC).

Lokon-Empung (North Sulawesi, Indonesia): A small eruption occurred again last Saturday, producing an ash plume that rose approx. 2 km and drifted northeast, caused a temporary closure of the Manado airport. The explosion occurred around 23:50 local time a vent in or or near Tompaluan crater. The volcano remains at alert level 3 (“siaga”) on a scale of 1-4 and a safety zone of 2.5 km around the crater is recommended as similar, sudden explosions are likely to occur again from time to time.

Kilauea (Hawai’i): No significant changes have occurred at the ongoing eruption on both the summit vent (Halema’uma’u lava lake) and the east rift zone. During the past days, lava flows have resurfaced most of the interior of what is left of Pu’u ‘O’o crater. The lava lake at Kīlauea’s summit remains active, and periodically rises and falls along with cycles of inflation and deflation. At the moment, summit tilt meters have been recording deflation. The new East Rift Zone lava flow northeast of Puʻu ʻŌʻō remains active within 8 km (5 mi) of the vent. The flow does not currently pose a threat to communities. Low levels of seismic activity continue across the volcano (HVO).
