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

Activity on Kīlauea’s lower East Rift Zone and at the summit of the volcano remains greatly diminished as of August 23. LERZ activity was limited to only a few ocean entries oozing lava and producing minimal laze plumes. Seismicity and ground deformation were negligible at the summit of Kīlauea, with no collapse event since August 2. However, hazardous conditions remain in both areas. Residents in the lower Puna and Kīlauea summit areas on the Island of Hawaiʻi should stay informed and heed Hawai‘i County Civil Defense closures, warnings, and messages (www.hawaiicounty.gov/active-al…). HVO daily status reports are posted at volcanoes.usgs.gov/volcanoes/k….

At Mauna Loa, HVO geophysical monitoring networks indicate that earthquakes and deformation are near background levels, and the USGS Volcano Alert level for the volcano remains at NORMAL.

HVO continues to closely monitor both Kīlauea and Mauna Loa and will report any significant changes on either volcano.

No earthquakes were reported felt in Hawaii this past week.
