The2014 Guerrero earthquake occurred with amoment magnitude of 7.2–7.3 that hit the state ofGuerrero, close toAcapulco,Mexico, on 18 April at 14:27:26 UTC (9:27 a.m. local time).[1][3][4] The epicenter occurred 265 kilometers southwest ofMexico City and at a depth of 24 kilometers.[5][6]Thrust motion at shallow depths is what caused the earthquake. This was broadly consistent with a slip on or near the Guerrero Seismic Gap, a boundary between theCocos andNorth American plates along thePacific coast approximately 200 kilometers long.[2][6][7] The shaking was felt in states as far away asPuebla andTlaxcala.[8]
The April 2014 earthquake was located just northwest of the rupture area of a 1957 Guerrero earthquake that measured 7.8 on themoment magnitude scale.[6] Since 1975, 23 earthquakes of magnitude 6.0 or greater have occurred within 200 kilometers of the same area as the April 2014 earthquake.[6]
