On October 24, 2025 at 19:05 UTC, a magnitude 3.0 intermediate depth earthquake struck 60 km WNW of Aleneva, Alaska, at a depth of 72.1 km and coordinates 58.3630°, -153.7640°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 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 5.5 mainshock that occurred 7 days ago 92 km NNW of Aleneva, Alaska. Since the mainshock, the USGS has recorded 4 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 3.0 earthquake near Aleneva, Alaska?

The magnitude 3.0 earthquake that struck 60 km WNW of Aleneva, Alaska on October 24, 2025 at 19:05 UTC had a depth of 72.1 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 3.0 earthquakes can continue for several days and gradually diminish over time.

Is this the same earthquake as the M5.5 one earlier?

No. This magnitude 3.0 earthquake is an aftershock of the larger magnitude 5.5 mainshock that occurred earlier 92 km NNW of Aleneva, Alaska. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

Understanding This Data

Magnitude 3.0 earthquakes are typically only recorded by instruments.
