There was no tsunami threat to Hawaiʻi following a 4.0 earthquake reported at 3:20 p.m. on Monday, Sept. 5, 2022. The earthquake was located about 7 miles east-northeast of Pāhala on Hawaiʻi Island, at a depth of 20 miles below sea level. 

Scientists with the USGS Hawaiian Volcano Observatory say the quake was part of a seismic swarm under the Pāhala area, which has been going on since 2019. Earthquakes in this region have been observed at least as far back as the 1960s, according to the HVO.
