Soil Liquefaction and Other Seismic-Associated Phenomena in the City of Chone during the 2016 Earthquake of Coastal Ecuador

The city of Chone, being situated on the Ecuadorian coast, was affected due to close-by epicenter earthquake 16 April 2016, which reached a magnitude Mw 7.8. This catastrophic event presented settlements in ground, sand boils and land subsidence, most damaging variety civil works among these several buildings. main objective current study is select data using standard penetration test (SPT) for evaluation probability liquefaction considering maximum acceleration seismic risk amax = 0.5 g. With tabulated information, hazard map generated where safety factor 1228 obtained, determining potentially liquefiable strata at an approximate depth between 9 11 m. Hereby, we were able demonstrate results that obtained experimentally through quantitative analysis, indicating urban area Chone has high liquefaction, supported presence Holocene-aged soils developed alluvial deposits, located alluvium mid catchment area. novel research, combination used tools evaluation, provides relevant contribution territorial planning management construction, addition reorganization canton as example different regions worldwide with similar geodynamics, soil mechanics vulnerabilities.
