The HVO’s seismic station recorded two earthquakes with a maximum magnitude of a 4.3 and 4.6 at 01:58 local time last night.
The first M 4.3 quake was widely felt on the Island of Hawai‘i and with a depth of 34 km located about 8 km NE of Pāhala, followed 8 seconds later by another, stronger magnitude-4.6 quake at 32 km depth located 9 km NE of Pāhala, slightly SE of the 1st earthquake.
The HVO reports: „These earthquakes had no apparent effect on Kīlauea or Mauna Loa volcanoes and appear to be part of the 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.“
