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

There was 1 event with 3 or more felt reports in the Hawaiian Islands during the past week. On January 27, 2019 at 08:24 a.m. HST, a magnitude-3.5 earthquake occurred in the upper Southwest Rift Zone of Mauna Loa at a depth of -0.5 km (0.3 mi above sea level).

Deformation signals are consistent with refilling of the middle ERZ. Sulfur dioxide emission rates have been below detection limits in the lower ERZ since early September, though minor amounts of volcanic gas are still present.

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 (

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