On June 11, 2024 at 18:15 UTC, a magnitude 2.8 shallow crustal earthquake struck 9 km NE of Pāhala, Hawaii, at a depth of 33.6 km and coordinates 19.2557°, -155.4108°.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 201 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.

This earthquake is part of an ongoing aftershock sequence following the magnitude 5.2 mainshock that occurred 22 hours ago 42 km ESE of Naalehu, Hawaii. Since the mainshock, the USGS has recorded 22 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions

How strong was the magnitude 2.8 earthquake near Pāhala, Hawaii?

The magnitude 2.8 earthquake that struck 9 km NE of Pāhala, Hawaii on June 11, 2024 at 18:15 UTC had a depth of 33.6 km. 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 2.8 earthquakes can continue for several days and gradually diminish over time.

Is this the same earthquake as the M5.2 one earlier?

No. This magnitude 2.8 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 42 km ESE of Naalehu, Hawaii. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

Understanding This Data

Magnitude 2.8 earthquakes are typically only recorded by instruments.
