In the Mexican city of strong earthquake Natural Disasters
December 11 at 19:47 local time near the Mexican city of Iguala was recorded earthquake of 6.5 points. Fortunately, the hypocenter was located at a depth of 64.9 km, and the epicenter at 42 km southwest of the city of Iguala, 56 km south-east of Arseliya, 62 km north-north-west of Chilpancingo and 166 km south-southwest of Mexico City.
About the event there are various data that are significantly different from each other. The U.S. Geological Survey (USGS) has established a range of earthquake intensity from 6.7 to 6.5. Seismological Service of Mexico said the strength of 6.8 points and a depth of 61 km, the National University of Mexico (UNAM) — the power of 6.5 points and a depth of 58 km, claiming that the earthquake other geographical coordinates.
According to the European Mediterranean Seismological Centre (EMCS) earthquake had a depth of 6.7 and by 61 km. Seismological Service of Mexico considers that the epicenter of the earthquake was in Zumpango del Rio, that is, just 15 km from Chilpancingo.
These UNAM, an earthquake measuring 6.5, depth 58 km
These USGS, an earthquake of magnitude 6.5, depth 64 km
The shaking lasted about 47 seconds, which in theory could harm thousands. USGS PAGER event awarded the status of "yellow alert" for the damage (43%) and economic losses (41%). There is information on the three affected local residents. In Chilpancingo damaged several houses and a church.
Earthquake in Mexico related to the subduction type and was the result of bending oceanic plate under the North American. For these earthquakes depth of 64 km is acceptable. Damage to buildings in areas far from the epicenter (eg, Mexico), possibly because of the soft alluvial soil, which only enhances the shaking.
Over the past 110 years, the region often suffered from earthquakes. In one Chilpancingo they occur every 30 years.
