On January 1, 2025 at 20:51 UTC, a magnitude 3.1 shallow crustal earthquake struck 10 km E of Pāhala, Hawaii, at a depth of 30.0 km and coordinates 19.2073°, -155.3805°. The earthquake was reported felt by 2 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.4 (light).

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 3.1 earthquake near Pāhala, Hawaii?

The magnitude 3.1 earthquake that struck 10 km E of Pāhala, Hawaii on January 1, 2025 at 20:51 UTC had a depth of 30.0 km. It was felt by 2 people with maximum shaking intensity of MMI 3.4 (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 3.1 earthquakes can continue for several days and gradually diminish over time.

Understanding This Data

Magnitude 3.1 earthquakes are typically only recorded by instruments.
