Magnitude 7.7 Quake Hits Flores Along Deadly 1992 Rupture Zone

A magnitude 7.7 earthquake struck Indonesia's Flores region on August 15, 2026, at just 15 km depth along the Sunda-Banda arc — the same segment that produced the 1992 M7.8 quake and tsunami killing roughly 2,500. BNPB reports two deaths in Sikka district. The shallow depth and historic precedent put nearby fault segments under close watch for aftershock-driven stress transfer.
