Indonesia hit by 7.7 quake sparking local tsunami warning

Indonesia issued a local tsunami warning after a 7.7-magnitude earthquake near Flores Island, followed by three aftershocks (5.9, 5.6, 6.1). Authorities urged coastal residents to move to higher ground and avoid beaches, while Australia reported no tsunami threat for now. The USGS warned casualties and damage are possible, with about 500,000 people exposed to very strong shaking; Indonesia sits on the Ring of Fire and has a history of major quakes, including the 2004 Sumatra disaster.
