Volcano Watch: Kilauea activity update for April 11, 2019

(Activity updates are written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.)

This wide-angle video shows the southwest portion of Kīlauea caldera in the area of Halema‘uma‘u. Faint plumes of volcanic gas are rising from yellow fumaroles on the walls of the deep conical pit. Overall, no significant changes were observed at the summit on today’s overflight. Video taken Monday, April 8, 2019 courtesy of U.S. Geological Survey

Kῑlauea Volcano is not erupting and its USGS Volcano Alert level remains at NORMAL.

Rates of seismicity, deformation, and gas release have not changed significantly over the past week. Deformation signals are consistent with refilling of Kīlauea Volcano’s deep East Rift Zone (ERZ) magma reservoir. Sulfur dioxide emission rates on the ERZ and at Kīlauea’s summit remain low and have been steady over the past several months.

Two earthquakes with three or more felt reports occurred in Hawaiʻi during the past week: a magnitude-2.6 quake 27 km (17 mi) west of Pepeʻekeo at 25 km (16 mi) depth on April 10 at 1:11 p.m. HST, and a magnitude-0.9 quake 16 km (10 mi) northwest of Volcano at 7 km (4 mi) depth on April 6 at 6:37 p.m. HST.  

Hazards remain at the lower ERZ and summit of Kīlauea. Residents and visitors near the 2018 fissures, lava flows, and summit collapse area should heed Hawai‘i County Civil Defense and Hawaiʻi Volcanoes National Park closures and warnings. HVO continues to closely monitor Kīlauea for any sign of increased activity.

The USGS Volcano Alert level for Mauna Loa remains at NORMAL.
