A second earthquake has struck Indonesia, following a powerful 7.7 magnitude quake earlier today. The U.S. Geological Survey confirmed the latest tremor occurred off the coast of eastern Indonesia. Details regarding the magnitude and potential impact of the second quake remain limited. This follows the initial major earthquake which prompted tsunami warnings that were later lifted. Authorities are currently assessing the damage and potential casualties from the first, stronger quake. The region is located within the Pacific Ring of Fire, making it prone to significant seismic activity. Residents are urged to remain vigilant for potential aftershocks.
