Catastrophe modelling company AIR worldwide has analyze a bulletin the earthquake of magnitude 7.4 , Southwestern Mexico yesterday taken.
Dr. Tao Lai, principal engineer at AIR worldwide, said that the "Tectonic setting of the Western Oaxaca is dominated by the subduction of the Cocos plate under the North American plate along a zone known generates events earthquake as middle American trench, repeated large brightness." Since 1973, the region has seen within 200 km [125] from the epicentre of the today's event 20 seismic events up to 6.0 m and seven events of more than 7.0 m. "In the year 2010 a M6. 3 earthquake occurred [32.5 km] 52 km southeast of today's earthquake, and in 1982 a M7. 2 event occurred about 7 km [4.375 km] from the today's degraded."
The epicenter of the quake was located southwest of the town of Ometepec in the State of Guerrero, where supposedly 500 houses were damaged. "The earthquake most was in the neighboring state of Oaxaca," said AIR; "also there damages have been but so far minimal reports;" "People put the quake not them to the ground believed strongly but for example fall from the shelves,."
According to the most homes in Mexico concrete base are air. "Stone structures generally fall into one of three classifications: masonry, narrow masonry and unreinforced masonry reinforced." Unreinforced masonry buildings are to shake one of the most endangered types of construction damage. Commercial building in Mexico are primarily of modified masonry or concrete, and withstand better ground motion.
"In large urban areas, like for example Mexico City families in five, fifteen floors, the meisten-, upper middle class living high reinforced concrete commercial apartments." "These buildings are generally well designed and built with high-quality materials."
AIR analysis indicates that "due to the repetitive and destructive nature of the earthquake in Mexico, building codes in this country among the most comprehensive in the world are."
However, it also showed that there "is no national codes." Instead more than 2,400 communities in Mexico staged enforces an its own rules, and thus the seismic performance is strongly influenced by local construction of practices building in Mexico. Building Damageability building code exacerbated by bad processing, inadequate materials and lack of enforcement.
"It is in the very early aftermath of this event, and source parameters can change as reports come seismic networks in Mexico and around the world continue to." "Air collects the data available for this event and will provide additional information if that justified by this event."
