Hawaiian Volcano Observatory reported a magnitude-4.4 earthquake struck at 5:16 p.m. Thursday (March 12) about 8 miles east-southeast of Pāhala in the southern portion of the Big Island at a depth of 18 miles.

The quake had no apparent impact on either Mauna Loa or Kīlauea volcanoes and is part of the seismic swarm under the Pāhala area, which has been ongoing since 2019.

Earthquakes in this region have been observed as far back as at least the 1960s.
