Nearly three days after an 8.8-magnitude earthquake, rescuers in the hardest-hit areas, including the city of Concepcion, Chile, and the Maule and Bio Bio regions, scrambled to reach possible . The moment-magnitude scale is logarithmic, so an increase of one unit means an earthquake is 10 times bigger, with about 30 times the energy produced. The February 27 th , 2010 Maule earthquake was a powerful moment magnitude 8.8 event that caused extensive damage in over 80 mid-rise reinforced concrete shear wall buildings in Chile. The primary goal was to understand how the Chilean society and relevant organizations responded to the magnitude 8.8 Maule earthquake that struck the region on . On 27 February 2010, a strong earthquake, which reached a magnitude of 8.8 on the moment magnitude scale, hit central Chile. This earthquake originated about 230 km north of the source region of the magnitude 9.5 earthquake of May, 1960 the largest instrumentally recorded earthquake in the world. The signature of seismic ionospheric perturbation was observed for the Maule earthquake by Galvan et al. Master of Science . In this article, we discuss AIR's enhanced methodologies for modeling earthquake risk, which form the cornerstone of AIR's new and updated earthquake models for South America slated for release in summer 2015. 1655 deaths A month later, the Maulé earthquake struck near Santiago, Chile. 1. This earthquake is associated with the subduction process of the Nazca plate beneath the South American plate, and it is one of the largest magnitude events to have produced strong motion recordings world-wide. The Constitución-Concepción or Maule segment in central Chile between ~35.5°S and 37°S was considered to be a mature seismic gap, rupturing last in 1835 and being seismically quiet without any magnitude 4.5 or larger earthquakes reported in global catalogues. The February 27, 2010, M 8.8 Chilean (Maule) earthquake occurred as the result of shallow thrust faulting generated at the gently sloping plate boundary fault that conveys the Nazca plate eastward and downward beneath the South America plate. In February 2010, an 8.8 magnitude earthquake killed more than 700 people and affected more than 2 million others . This event is the second largest in magnitude recorded in It shook the river valleys where he was studying sediment transport—and it shook him. The tremor was recorded early morning on Thursday 26 August 2021 at 4:34 am local time, at an intermediate depth of 88 km below the surface. This subduction interplate thrust earthquake occurred at the convergence of the Nazca (oceanic) plate with the South American continental plate. The quake was at a depth of 6.2 miles (10 km).
