On January 25, 2023 at 17:17 UTC, a magnitude 3.2 shallow crustal earthquake struck 16 km E of Naalehu, Hawaii, at a depth of 37.1 km and coordinates 19.0497°, -155.4255°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.1 (light).

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 985 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 99 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 3.2 earthquake near Naalehu, Hawaii?

The magnitude 3.2 earthquake that struck 16 km E of Naalehu, Hawaii on January 25, 2023 at 17:17 UTC had a depth of 37.1 km. It was felt by 1 person with maximum shaking intensity of MMI 3.1 (light). For context, this was a minor earthquake typically detected only by instruments.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.2 earthquakes can continue for several days and gradually diminish over time.

Understanding This Data

Magnitude 3.2 earthquakes are typically only recorded by instruments.
