Volcano Watch: Kilauea activity update for November 29, 2018

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

KÄ«lauea is not erupting. Low rates of seismicity, deformation, and gas release have not changed significantly over the past week.

Earthquakes continue to occur primarily at KÄ«lauea’s summit area and south flank, with continued small aftershocks of the May 4, 2018, magnitude-6.9 quake. Seismicity remains low in the lower East Rift Zone (ERZ).

Deformation signals are consistent with slow refilling the middle ERZ. At the summit, tiltmeters showed little significant change this week.

Hazardous conditions still exist at both the lower ERZ and summit. Residents in the lower Puna District and Kīlauea summit areas on the Island of Hawaiʻi should stay informed and heed Hawai‘i County Civil Defense closures, warnings, and messages (http://www.hawaiicounty.gov/active-alerts).

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

No Hawaii earthquakes received three or more felt reports (minimum to be recounted here) this past week.
