On June 29, 2023 at 23:11 UTC, a magnitude 2.1 earthquake struck 23 km W of Volcano, Hawaii. It arrived roughly 4 hours after a larger magnitude 2.3 mainshock in the same 20 km area, placing it within the typical aftershock window. This very shallow event was close enough to the surface that even modest magnitudes can produce significant local shaking. See the M2.1 event page for the full report, ShakeMap, and citizen-reported intensity data.
