M6.2 Earthquake near Near the coast of Bio-Bio, Chile — November 13, 2022
2022-11-13 02:24:57 UTC (2022-11-13) · approx. 9:24 PM UTC-5 local
Felt by 144 people across surrounding communities. Maximum shaking intensity MMI 6.9 (very strong).
On November 13, 2022 at 02:24 UTC, a magnitude 6.2 shallow crustal earthquake struck near Near the coast of Bio-Bio, Chile, at a depth of 18.0 km and coordinates -37.4652°, -73.6757°. The earthquake was reported felt by 144 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.9 (very strong). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 104 seismic stations with good location accuracy and was assigned a USGS significance rating of 742, making it a moderate-impact event. The nearest populated place is Lebu (population 22,345).
Physical scale: An earthquake of magnitude 6.2 releases seismic energy equivalent to roughly 30 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 11 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 6.2 earthquakes can continue for weeks to months 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 6.2 event is significantly smaller than that historical record.
