The 2018 Oaxaca earthquake occurred on February 16, 2018 at 17:39 local time (23:39 UTC) in the Sierra Madre del Sur in Oaxaca state in Southern Mexico. It had a magnitude of 7.2 on the moment magnitude scale and a maximum felt intensity of VII (very strong) on the Mercalli intensity scale. The hypocenter was located at a depth of 24.6 km and approximately 37 km northeast of Pinotepa de Don Luis.
Descending and ascending Sentinel-1 imagery were acquired and processed through GeoHub, producing wrapped interferograms depicting the ground deformation pattern. Up to 40 cm of uplift of the ground surface was observed near the coast, showing that the location of the earthquake was close to the coast, far from the initial USGS epicenter location.
