M4.4 Earthquake 159 km NW of Vallenar, Chile — November 12, 2024
2024-11-12 23:06:41 UTC (2024-11-12) · approx. 6:06 PM UTC-5 local
On November 12, 2024 at 23:06 UTC, a magnitude 4.4 shallow crustal earthquake struck 159 km NW of Vallenar, Chile, at a depth of 35.5 km and coordinates -27.6614°, -72.0089°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 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 5.1 mainshock that occurred 13 days ago 121 km NW of Vallenar, Chile. Since the mainshock, the USGS has recorded 0 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 4.4 earthquake near Vallenar, Chile?
The magnitude 4.4 earthquake that struck 159 km NW of Vallenar, Chile on November 12, 2024 at 23:06 UTC had a depth of 35.5 km. For context, this was a light earthquake commonly felt near the epicenter.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.4 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.1 one earlier?
No. This magnitude 4.4 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 121 km NW of Vallenar, Chile. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
