It was positioned west of Ometepec, Guerrero, with a focal depth of 24 km (14.9 mi), and was lightly felt in many adjacent areas. Buildings swayed with the tremor in Mexico City, prompting evacuations and causing panic among many. Following the quake, police patrolled city streets for safety reasons and damage assessments were carried out across the affected region. There were no casualties, though two local police stations suffered slight damage. A number of light aftershocks succeeded the main event, of which the strongest measured a magnitude of 4.1 (ML). Geology The magnitude 5.7 (Mw) earthquake occurred inland near the southern coast of Mexico at a depth of 24 km (14.9 mi), with a duration of nearly one minute and an epicenter about 55 km (34 mi) west of Ometepec, Guerrero.http://thehivedaily.com/blog/2011/05/05/strong-earthquake-rocks-southern-mexico/ Strong earthquake rocks southern Mexico Fox News EFE 5 May 2011 5 May 2011 https://web.archive.org/web/20110509004717/http://thehivedaily.com/blog/2011/05/05/strong-earthquake-rocks-southern-mexico/ 9 May 2011 dead In the region, the Cocos, North American, and Caribbean plates converge and create a tectonic zone of continuous seismic activity.http://mexico.cnn.com/nacional/2011/05/05/se-registra-sismo-de-58-grados-con-epicentro-en-guerrero México registra un sismo de 5.5 grados con epicentro en Guerrero 5 May 2011 CNN México Staff Writer 5 May 2011 es The quake struck near the eastern periphery of the Guerrero seismic gap, which extends from Acapulco to Ixtapa–Zihuatanejo and contains enough seismic energy to generate an earthquake of up to magnitude 7.5, but it did not cause the gap to rupture.http://www.radioformula.com.mx/notas.asp?Idn=171465 radioformula.com.mx Ciuda danos deben estar preparados ante sismos: SSN Grupo Fórmula amd 5 May 2011 6 May 2011 es 27 September 2011 https://web.archive.org/web/20110927132824/http://www.radioformula.com.mx/notas.asp?Idn=171465 dead Initial estimates from the USGS placed its intensity at a magnitude of 5.8 (Mw);https://neic.usgs.gov/neis/bulletin/neic_c000362l_d.html Magnitude 5.8 Guerrero, Mexico 5 May 2011 6 May 2011 United States Geological Survey dead https://web.archive.org/web/20110510010741/http://neic.usgs.gov/neis/bulletin/neic_c000362l_d.html 10 May 2011 the National Seismological Service registered the earthquake at magnitude 5.5 (ML).http://www.ssn.unam.mx/website/jsp/localizacion.jsp?archivo=110505_082407.gif&evento=14&fecha=2011-05-05&hora=08:24:07&latitud=16.61&longitud=-98.91&profundidad=11&magnitud=5.5&epicentro=55%20km%20al%20OESTE%20de%20%20OMETEPEC,%20GRO%20%20%20%20%20%20%20%20%20&regresar=ultimos Localización del sismo seleccionado: Magnitud 5.5 SSN 5 May 2011 6 May 2011 ssn.unam.mx esApril 2019 InternetArchiveBot yes thumb|right|USGS shake map Owing to the moderate magnitude of the quake, significant shaking was felt only in localized parts of Costa Chica, registering strongest at VI (strong) on the Mercalli scale in Azoyú and V (moderate) in populous areas around the epicenter. Lighter ground motions (MM IV–III) were perceived in much of Guerrero, including Acapulco and Chilpancingo, with weak tremors (MM II) reported as far away as in Mexico City, about 300 km (187 mi) from the epicenter.http://www.alternet.org/rss/breaking_news/579896/mexico_city_rocked_by_5.8_earthquake/ Mexico City rocked by 5.8 earthquake AlertNet Agence France-Presse 5 May 2011 news.yahoo.com 6 May 2011 The capital city rests on a former lakebed of largely unconsolidated sedimentary layers, so earthquake shaking in its vicinity is generally amplified. Aftershocks By 6 May, a total of five light aftershocks had occurred near the earthquake's epicenter. Of the five, the first registered a magnitude of 3.7 (ML) and struck about 15 minutes after the main shock, and was succeeded by a magnitude 3.9 (ML) tremor at 10:09 local time. Two similar quakes of minor intensity struck the region the next day; however, the strongest and final aftershock registered a magnitude of 4.1 (ML) and occurred at 04:00 in the morning. Impact and response Despite relatively strong ground motions, damage to the area was very limited; structures around the epicenter were a mix of fairly vulnerable and resistant to earthquake shaking. Buildings swayed with the tremor in Mexico City, causing panic among many citizens and prompting some to evacuate.http://www.deseretnews.com/article/700125208/Earthquake-shakes-wide-area-of-southern-Mexico.html https://web.archive.org/web/20110410212213/http://www.deseretnews.com/article/700125208/Earthquake-shakes-wide-area-of-southern-Mexico.html dead 10 April 2011 Earthquake shakes wide area of southern Mexico Deseret News Publishing Company Associated Press 5 May 2011 7 May 2011 Several schools in Guerrero were evacuated as a safety precaution.http://www.veracruzanos.info/2011/05/distrito-federal-amanece-con-sismo-de-5-5-grados-en-la-escala-de-richter/ Sacude sismo de 5.5 grados en la escala de Richter Ciudad de México; Saldo Blanco veracruzanos.info Noticias Veracruz Staff Writer 5 May 2011 7 May 2011 es https://web.archive.org/web/20120315184918/http://www.veracruzanos.info/2011/05/distrito-federal-amanece-con-sismo-de-5-5-grados-en-la-escala-de-richter/ 15 March 2012 dead The earthquake and its aftershock sequence contributed to intermittent power outages in Acapulco; more than 40,000 residences in some 40 districts remained without power by the next day.http://www.eluniversal.com.mx/notas/763964.html Sismos afectan alumbrado público de Acapulco 6 May 2011 7 May 2011 Sandoval, Adriana Covarrubias El Universal eluniversal.com.mx es 10 May 2011 https://web.archive.org/web/20110510151302/http://www.eluniversal.com.mx/notas/763964.html dead There were no reports of major losses or fatalities in the wake of the tremor, though two police stations located in Acapulco and Marquelia suffered light damage.http://www.eluniversal.com.mx/notas/763663.html Sismo daña cuartel de policía de Acapulco 5 May 2011 Covarrubias, Adriana El Universal 7 May 2011 eluniversal.com.mx es 11 October 2012 https://web.archive.org/web/20121011225716/http://www.eluniversal.com.mx/notas/763663.html deadhttp://www.radioformula.com.mx/notas.asp?Idn=171555 Causa sismo cuarteaduras en sede policial en Guerrero radioformula.com.mxn Notimex Grupo Fórmula 5 May 2011 8 May 2011 es 27 September 2011 https://web.archive.org/web/20110927132831/http://www.radioformula.com.mx/notas.asp?Idn=171555 dead Elsewhere, some fallen roof tiles and small landslides occurred east of the epicenter in Cuautepec.http://elsoldelacostadeayutla.com.mx/index.php?option=com_content&id=290%3Asolo-sustos-en-la-costa-grande-por-sismo Solo sustos en la Costa Grande por sismo 7 May 2011 22 May 2011 Sol de la Costa esApril 2019 InternetArchiveBot yes Prior to the arrival of seismic waves in Mexico City, seven of twelve earthquake sensors near the coast of Guerrero detected a "potentially significant quake".

In reality, roughly 900 earthquakes of similar intensities to that of the Guerrero earthquake are required per year to total the energy unleashed by a magnitude 7.5 event. Many locals perceived an apparent increase in recent earthquake occurrences, though at the time seismologists registered normal levels of seismic activity in the area.http://www.eluniversal.com.mx/notas/763781.html Evitan minisismos un terremoto mayor eluniversal.com.mx El Universal Montes, Rafael/Marisol 6 May 2011 7 May 2011 es 9 May 2011 https://web.archive.org/web/20110509084942/http://www.eluniversal.com.mx/notas/763781.html dead In 2009, a similar magnitude 5.8 Mw earthquake struck Guerrero near Acapulco at a depth of 35 km (22 mi), killing at least two people.https://earthquake.usgs.gov/earthquakes/dyfi/events/us/2009fya9/us/index.html M5.8 – Guerrero, Mexico 27 April 2009 17 May 2011 United States Geological Survey https://web.archive.org/web/20121016170433/http://earthquake.usgs.gov/earthquakes/dyfi/events/us/2009fya9/us/index.html 16 October 2012 deadhttp://www.foxnews.com/story/0,2933,518131,00.html https://web.archive.org/web/20090429032104/http://www.foxnews.com/story/0,2933,518131,00.html dead 29 April 2009 Earthquake shakes buildings in Mexico Associated Press 27 April 2009 17 May 2011 Fox News See also List of earthquakes in 2011 List of earthquakes in Mexico Seismicity in Mexico References External links Video – CNN Mexico News Report (Spanish) 16497740 Category:Earthquakes in Mexico Category:2011 in Mexico Category:2011 earthquakes Category:May 2011 in Mexico Category:2011 disasters in Mexico
