Felt by 22 people across nearby locations.
On June 22, 2026 at 05:11 UTC, a magnitude 2.8 shallow crustal earthquake struck 5 km S of Honoka‘a, Hawaii, at a depth of 13.6 km and coordinates 20.0278°, -155.4652°. This earthquake was detected by 49 seismic stations with good location accuracy and was assigned a USGS significance rating of 125, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 215 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 49 m — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Hawaii, a region characterized by intraplate volcanic activity over the Hawaiian mantle plume hotspot, with seismicity driven by magma intrusion and flank instability. View all earthquakes in Hawaii.
