A strong and shallow earthquake registered by the USGS as M6.0 hit near Archipelago of San Andrés, Providencia and Santa Catalina (Colombia), the Caribbean Sea at 03:40 UTC on November 25, 2018 (21:40 LT, November 24). The agency is reporting a depth of 10 km (6.2 miles). EMSC is reporting M6.1 at a depth of 10 km.

The quake was preceded by M4.6 at 01:19 UTC and followed by M4.4 and M4.2 at 05:16 and 05:28 UTC, respectively.
