Summary

Geology Expert Explains

Geology expert Dwikorita Karnawati said the quake was caused by the Flores back-arc thrust fault, a west-east thrust system that keeps the region at high seismic risk.
Indonesia’s geophysics agency noted the same coastline suffered a magnitude-7.5 quake in December 1992 that killed over 2,500 people, highlighting historic vulnerability.
State utility Perusahaan Listrik Negara said power supply was nearly fully restored while crews continued repairing distribution lines province-wide.

History

Historical Context

The 2004 Indian Ocean earthquake-tsunami, a magnitude 9.2 megathrust off Aceh that killed about 230,000 people, spurred the Indian Ocean warning system and a military-civil response led by Indonesia’s BNPB and the United Nations. That framework enabled rapid troop and aid deployment after the August 15 2024 magnitude 7.7 Flores quake, which has caused 54 deaths and displaced nearly 10,000 people.
