New seismic monitoring center in South America to assess the liquefaction risk posed by subduction earthquakes …
The east of Cali is composed of loose sand deposits with high water table levels. This condition and the high seismic hazard of the city make cyclic liquefaction one of the main hazards in the city, which may affect more than 600,000 citizens and important infrastructures such as the city''s main drinking water treatment plants. Therefore, it was …
Updated concepts of seismic gaps and asperities to assess great earthquake hazard along South America …
The focus here is on the subduction zone extending ~6,500 km along the western coast of South America, where the Nazca plate is underthrusting the South American plate. The occurrence of 6 very large megathrust earthquakes ( M W > 7.8) along this plate boundary during the last 21 y ( Fig. 1 ) has reinforced several fundamental …
