July 30, 2025 — A massive earthquake struck off the coast of northern Chile early Wednesday, prompting widespread tsunami warnings and evacuations along the Pacific coasts of South America. However, as of midday, U.S. authorities reported that the most severe tsunami risks for Hawaii and the U.S. West Coast have largely subsided.
Major Earthquake Triggers Pacific Tsunami Alerts
The U.S. Geological Survey (USGS) recorded the quake at a magnitude of 8.6, occurring at approximately 2:41 a.m. local time, about 65 miles west of Iquique, Chile. The tremor was felt strongly across northern Chile and southern Peru, causing temporary power outages and minor structural damage in several coastal cities.
The Pacific Tsunami Warning Center (PTWC) immediately issued tsunami alerts for Chile, Peru, Ecuador, and Colombia, urging residents in low-lying coastal areas to move to higher ground. Chilean authorities activated nationwide emergency protocols, closing ports and suspending coastal transportation.
Evacuations and Preparedness in South America
- Chilean officials ordered evacuations for over 150,000 residents in coastal communities.
- Peruvian authorities issued similar evacuation orders for northern beaches, and schools in affected regions were closed for the day.
- Initial tsunami waves, ranging from 1 to 3 meters (3 to 10 feet), were reported in several Chilean and Peruvian towns; no major injuries have been confirmed as of this writing.
U.S. Monitors Situation, Risk Diminishes
After urgent overnight monitoring, the National Weather Service and PTWC downgraded the tsunami threat for Hawaii and the U.S. West Coast by late morning Eastern Time. Small surges and unusual currents were observed in parts of California and Hawaii, but no significant flooding or damage has been reported.
- Beachgoers in California, Oregon, Washington, and Hawaii were advised to avoid the water and remain vigilant for residual currents.
- Ports in Los Angeles, San Francisco, and Honolulu implemented precautionary measures but have since resumed normal operations.
Aftershocks and Ongoing Assessment
Seismologists warn that strong aftershocks are likely in the coming days. Emergency services in Chile and Peru remain on high alert, and the International Federation of Red Cross has mobilized teams to assist with evacuation centers.
U.S. officials continue to monitor the Pacific for any late-developing hazards, but experts emphasize that the threat to American coastal communities appears to have passed.
What to Know
- An 8.6 magnitude earthquake struck off northern Chile early July 30.
- Tsunami warnings and evacuations were ordered in Chile, Peru, Ecuador, and Colombia.
- The U.S. West Coast and Hawaii faced only minor surges; official warnings have been lifted.
- Authorities urge continued caution in affected South American regions as aftershocks continue.
