Communities along a 700-mile stretch of Alaska's southern coast were ordered to evacuate to higher ground following a 7.3 magnitude earthquake on Wednesday. The earthquake, which struck south of Sand Point in the Aleutian chain, prompted the National Tsunami Warning Center to issue a warning for a large coastal area. While the warning was later downgraded and canceled, communities took precautionary measures, with some residents moving to higher ground or inland. Reports of significant damage were minimal, with some broken bottles at a local store being the most notable consequence. Seismologists noted that this was the fifth earthquake of magnitude 7 or greater in the same area since 2020, indicating ongoing seismic activity.

A strong 7.0 magnitude earthquake struck near Tonga, prompting an initial tsunami warning that was later lifted. The U.S. Geological Survey reported the quake's depth at 29 kilometers (18 miles), centered about 100 kilometers (62 miles) northeast of the main island. Hours later, a second 6.1 magnitude quake hit the same area. The Pacific Tsunami Warning Center issued an alert, but later announced there was no tsunami threat. Tonga's disaster management office also canceled its warning. Mafua Maka, the agency's director, reported no casualties or structural damage, though further assessments were planned. Tsunami sirens sounded, and residents moved inland before being given the all-clear. Social media posts from Tongans described the experience, with reports of items falling from shelves and prolonged shaking. Tonga, located on the Pacific Ring of Fire, is comprised of 171 islands and has a population of just over 100,000. The low-lying island nation suffered a devastating tsunami in 2022 following a volcanic eruption.
