Tsunami warning issued after magnitude 7.7 earthquake strikes Indonesia

A powerful magnitude 7.7 earthquake struck Indonesia's Flores region on Saturday, triggering a tsunami warning for the affected areas. The European-Mediterranean Seismological Centre (EMSC) reported the seismic event, which occurred at a depth of 35 kilometers.

The initial magnitude classification of the earthquake fluctuated, being reported as 7.5, then downgraded to 6.9, reclassified as 7.5, and finally upgraded to 7.7. The earthquake's epicenter was located in a region prone to seismic activity.

Following the initial powerful tremor, a second earthquake, measuring magnitude 6.3, was detected in the same vicinity at 6:13 a.m. local time. The EMSC conducted a tsunami evaluation before issuing the warning, indicating the potential for hazardous sea level changes.

Details regarding the impact, casualties, or damage caused by the earthquake and the subsequent tsunami warning were not immediately available as the situation was developing.
