The fault is named after Remolino Grande and El Charco, Nariño.[1]

Description

The Remolino-El Charco Fault extends through the Pacific coastal lowlands and plains of Colombia to the east of the city of Tumaco. The fault begins in the southwesternmost point of Colombia and runs towards Guapi.[2] It is close to and parallels the coast. It displaces alluvial fan sediments of the Patía, Mira, and Telembí Rivers and some Pleistocene marine terraces. The fault appears to be a southern continuation of the Naya-Micay Fault. The fault has a very well defined fault line on aerial photographs and satellite images. Pattern of deflection of streams suggests west side of fault is up.[1]
