Flores Back Arc Thrust Fault

From Wikipedia, the free encyclopedia

Flores Back Arc Thrust Fault is a major back-arc fault system lying an east-west striking (oriented) north vergent (dipping to the south) thrust fault that extends from eastern Java towards the islands of Flores and Timor and Alor. Above the main thrust fault are a series of imbricate (overlapping) thrust faults. These imbricate thrust faults are shallower in depth than the main Flores thrust.[1] Although the exact fault lines have not been established, these faults were thought to be responsible for the 2018 Lombok earthquakes.
