On Sunday, September 22 at 6:21 a.m. HST, a magnitude-3.7 earthquake occurred 2.2 mi (3 km) South-southwest of Pahala on the Island of Hawaiʻi at a depth of 18.4 mi (30.7 km) below sea level.  This earthquake is related to the ongoing swarm of earthquakes that has been going on since 2019 at depth beneath the Pahala area.  It has had no impact on the volcanic activity of Kīlauea volcano or the status of Mauna Loa volcano.  The recent eruption of Kīlauea remains paused with no resumption of activity as of this morning.

The USGS Hawaiian Volcano Observatory continues to monitor Hawaiian volcanoes for any changes.
