Site response and liquefaction hazard analysis of Hawassa town, Main Ethiopian Rift

The study area is located in one of the most earthquake prone regions southern Ethiopia, which characterized by small-to-intermediate occurrences causing damage to buildings. Predicting liquefaction hazard potential and local site effects are imperative manage reduce buildings loss lives. objectives this work were perform equivalent linear response analysis (ELA) shear wave velocity (Vs.)-based classify into different seismic classes based on European American codes. SPT-N Vs.30 values showed falls C D NEHRP (2015) code but B EC8 (2003) code. susceptibility was evaluated using grain size curves. Moreover, peak ground acceleration (PGA), spectral (SA), maximum strain (%), very critical understanding effects, estimated DeepsoilV.7 program. cyclic stress ratio resistance used calculate factor safety (FS). A index (LPI), probability (PL), induced failure (PG) assess liquefaction. (g) ranged from 0.166 0.281 g, whereas found be high at 0.1–1s. screening criteria revealed that highly susceptible FS < 1 for a liquefied site, > non-liquefied sites. In comparison sites, forecast has value 0–54.16, likely PL, PG. findings will helpful design structures solving practical challenges engineering.
