On January 24, 2021 at 00:07 UTC, a magnitude 5.7 intermediate depth earthquake struck 41 km ENE of Villa Presidente Frei, Ñuñoa, Santiago, Chile, Chile, at a depth of 109.5 km and coordinates -33.3533°, -70.1484°. The earthquake was reported felt by 283 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.6 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Chicureo Abajo (population 18,000).

Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 km — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Chile, a region characterized by the Peru-Chile Trench, where the Nazca Plate subducts beneath South America at 65-80 mm per year. The nearest mapped fault system is the Peru-Chile Trench. View all earthquakes in Chile.

What the Shaking Felt Like

At MMI 4.6 (moderate), people in the most strongly affected areas would have experienced: Mild shaking, similar to a passing truck. Hanging objects swing. Glasses and dishes may rattle. Not commonly felt outdoors.

It was felt by 283 people with maximum shaking intensity of MMI 4.6 (moderate). For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at -33.3533°, -70.1484°, which is 41 km ENE of Villa Presidente Frei, Ñuñoa, Santiago, Chile, Chile. The nearest populated place is Chicureo Abajo (population 18,000). View all earthquakes in Chile.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.7 earthquakes can continue for days to weeks and gradually diminish over time.

Has Chile had earthquakes this big before?

The largest recorded earthquake in Chile was the M9.5 Great Chilean earthquake of May 22, 1960. Today's magnitude 5.7 event is significantly smaller than that historical record.
