The earthquake occurred on the same overall structure, the Flores Back Arc Thrust Belt, however according to scientists it happened on a different thrust fault as there are many individual structures within the belt. There were 14 deaths and 1800 homes have been damaged, half severely, due to this event, including deaths on Sumbawa, following 2 deaths from the previous Lombok quake roughly 24 hours earlier. Heavy tiles fell from the local mosque, and 143 patients were being treated outdoors in makeshift tents for injuries on Sumbawa.
