ABSTRACT: The Chile Maule earthquake with magnitude 8.8 occurred off the coast of the Maule Region of Chile on February 27, 2010. Considering the damage produced by the 2010 Maule earthquake (Mw 8.8), we also estimated high-density macroseismic intensities at these cities, with values ranging from VI up to VIII on the MSK64 scale. government-owned reservoir dams, Coihueco and Lliu-Lliu, did suffer damage, although there was no water release because the reservoir water levels were low. The effects of structural irregularity and … The 27 February 2010 Maule, Chile, earthquake occurred during the driest time of the year, which implied that most of the soils in the slopes were not saturated and that the dams had extra freeboard. The Maule (Chile) earthquake of 27 February, 2010 has caused severe disruption and economic losses. With a magnitude of 8.8, it has been recorded as one of the largest earthquakes of the last century. The ground motion records from large subduction earthquakes, such as the Chile earthquake, are sparse. Since many homes were destroyed, many jobs will now be created for reconstruction. Fewer than 0.15 percent of the bridges in Chile’s inventory, most built after 1995, collapsed or suffered damage that rendered them useless. In the Bio-Bio Region, which includes the city of Concepción, the estimated number of severely damaged buildings is close to 20.
