A powerful earthquake struck the sea south of Chile and Argentina, prompting a short-lived tsunami alert and evacuation orders for coastal areas in the sparsely populated region near Antarctica.
Earthquake Details
The earthquake occured at 9:58 a.m. local time (12:58 p.m. GMT), originating 10 kilometers beneath the sea’s surface. The epicenter was located 218 kilometers south of Puerto Williams and approximately 2,500 kilometers south of Santiago, according to the University of Chile’s national seismological center. The center initially assessed the magnitude at 7.5, while the U.S. Geological Survey (USGS) measured it at 7.4.
evacuation Orders and Response
Chile’s National Service for Prevention and Response to Disasters (Senapred) and the Hydrographic and Oceanographic Service of the Navy (Shoa) swiftly issued evacuation orders. Senapred posted on X,formerly known as Twitter,urging people to evacuate the seaside sector of the Magallanes region due to the tsunami threat. A subsequent order called for the evacuation of the beach area of the Antarctic Territory.
Though, the tsunami alert and evacuation order were lifted shortly before noon local time (3 p.m.GMT).
juan Carlos Andrade,regional director of the Magallanes prevention and response service,stated,”Preventive evacuation is over. In other words, everyone resumes their activities.All sectors should operate normally, with the exception of all economic activities on the coast.”
Impact in Argentina
In neighboring Argentina, authorities in the province of Tierra del Fuego instructed the approximately 100 residents of Puerto Almanza to evacuate preventively to higher ground and suspend all aquatic activities and navigation in the Beagle Canal.
In Ushuaïa, located 75 kilometers from Puerto Almanza, civil protection secretary Pedro Franco told TN television that there was no alert for the city, but aquatic activities were suspended.He added that there was no damage to buildings.
Witness Accounts
Sofia Ramonet, a resident of Ushuaia, told AFP she was asleep when she “felt the bed moves a lot” in her third-floor apartment. “I looked up to the ceiling where I have a hanging lamp and it moved on one side, on the other. It lasted a considerable time.”
She added that she saw “a lot of people outside,frightened as they didn’t know what was going on or what to do.”
Antarctic Concerns
chile anticipated that the wave train generated by the earthquake would reach the coasts of the Antarctic Peninsula, with estimated wave heights between 0.3 and 1 meter. The Chilean military bases Bernardo O’Higgins and Arturo Prat in Antarctica were expected to be the first affected.
Evacuation Scenes
Television channels broadcast images of evacuations, showing people gathering in high areas away from the sea. The Chilean police posted a photo on X showing an officer pushing a person in a wheelchair to higher ground in Puerto Williams, a city of 2,800 residents closest to the epicenter. Videos also showed residents heading to higher ground in the coastal areas of the Magallanes region, home to 170,000 people.
Shirley Galley Galley, 41, who works at a fishing plant in Porvenir, located in the Strait of Magellan, told AFP, “I didn’t pay much attention to it until the alarms ring. There have been a little chaos because it is not normal that we feel tremors here.”
Chile’s Seismic Activity
Chile is one of the world’s moast seismically active countries, situated where the Nazca, South American, and Antarctic tectonic plates converge.
In 1960, Valdivia was devastated by a magnitude 9.5 earthquake, the most powerful ever recorded, which killed approximately 9,500 people. In 2010,an 8.8 magnitude earthquake and subsequent tsunami caused more than 520 deaths.
