This earthquake triggered a series of catastrophic disasters. Liquefaction occurring in many places led to massive damages. Following the earthquake, tsunamis up to 11 m high hit Palu bay and nearby coastal areas. This series of disasters claimed a great number of lives and caused losses of properties in the greater Palu area. A collaborative field investigation was performed to evaluate the earthquake impact. This paper provides an overview of the seismological, geological, and geotechnical factors that contributed to the catastrophe. Results of field investigations post 2018 Palu earthquake are reported in this manuscript with emphasize on the most devastated areas, namely Petobo, Sibalaya, Jono Oge, and Balaroa. In general, ground movements at these sites due to the earthquake were associated with multiple mechanisms, including liquefaction, landslide, lateral spreading, and breakage of adjacent water channels.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Coastal area,Field investigation,Geotechnical factors,Ground movement,Lateral spreading,Massive damage,Water channels[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This paper is based upon a field reconnaissance mainly supported by PusGen and HATTI.
