Felt by 41 people across nearby locations.
On September 25, 2024 at 23:01 UTC, a magnitude 3.2 shallow crustal earthquake struck 31 km SSW of Pa‘auilo, Hawaii, at a depth of 18.0 km and coordinates 19.7697°, -155.4548°. This earthquake was detected by 61 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 168, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 919 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 96 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.
