On July 26, 2026 at 20:30 UTC, a magnitude 2.8 shallow crustal earthquake struck 22 km SE of Waikoloa, Hawaii, at a depth of 23.1 km and coordinates 19.8163°, -155.6157°. This earthquake was detected by 56 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 120, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 208 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 48 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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 2.8 earthquakes can continue for several days and gradually diminish over time.

Has Hawaii had earthquakes this big before?

The largest recorded earthquake in Hawaii was the M7.9 Ka'u District earthquake of April 2, 1868. Today's magnitude 2.8 event is significantly smaller than that historical record.
