M2.4 Earthquake 13 km SSE of Volcano, Hawaii — December 5, 2023
2023-12-05 21:43:24 UTC (2023-12-05) · approx. 11:43 AM UTC-10 local
On December 5, 2023 at 21:43 UTC, a magnitude 2.4 shallow crustal earthquake struck 13 km SSE of Volcano, Hawaii, at a depth of 1.4 km and coordinates 19.3268°, -155.1952°.
Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 52.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 26 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 9 days ago 42 km ESE of Naalehu, Hawaii. Since the mainshock, the USGS has recorded 23 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 2.4 earthquake near Volcano, Hawaii?
The magnitude 2.4 earthquake that struck 13 km SSE of Volcano, Hawaii on December 5, 2023 at 21:43 UTC had a depth of 1.4 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 2.4 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 2.4 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.
