A powerful 7.4 magnitude earthquake struck today (May 2) near the southern coastal regions of Chile and Argentina, according to a report issued by the United States Geological Survey (USGS). The earthquake’s epicenter was located in the Drake Passage, approximately 219 kilometers (136 miles) south of Ushuaia, Argentina, at a depth of 10 kilometers (6 miles) below sea level.
Strong Tremors Felt in Ushuaia, No Major Damage Reported
Residents of Ushuaia—the world’s southernmost city—reported feeling strong tremors, with mild shaking also experienced in other parts of Argentina. However, no structural damage or casualties have been reported in Ushuaia, and no evacuation orders have been issued within the city.
Precautionary Measures and Tsunami Alerts
As a precaution, all maritime activities and navigation in the Beagle Channel have been temporarily suspended for at least three hours. Additionally, authorities in Puerto Almanza, a nearby village, have issued evacuation orders.
In Chile, authorities have issued a tsunami warning for all coastal areas of the Magallanes Region, citing the potential threat of tsunami waves. The Chilean National Disaster Prevention and Response Service (SENAPRED) has instructed residents along the coast and in Chilean Antarctic territories to evacuate to higher ground.
The Chilean Navy’s Hydrographic and Oceanographic Service (SHOA) has warned that tsunami waves could reach Antarctica within one hour, and other distant regions within 12 hours.
Calm Evacuations and No Reported Injuries
Residents in cities like Punta Arenas, Chile, evacuated calmly following siren alerts. No injuries or incidents of panic have been reported. According to the latest updates, there is no significant damage or loss of life reported in either Argentina or Chile.
Authorities in both countries are urging the public to remain calm and follow official guidelines.
Earthquake Characteristics and Expert Insights
According to USGS, this quake falls within the “strong” category, defined as earthquakes with magnitudes between 7.0 and 7.9, which can potentially cause significant damage over large areas.
The earthquake’s epicenter near the Drake Passage is notable, as the region lies along the boundary between the Antarctic Plate and the South American Plate, a known hotspot for seismic activity.
Luis Balbontín, regional spokesperson for SENAPRED, stated,
“Evacuation plans for coastal populations were immediately activated. We focused especially on moving residents from low-lying areas to higher ground. These are purely precautionary measures, and we are closely monitoring the situation.”
Local reporter Roberto Mendoza from Punta Arenas added,
“The evacuation process was orderly and efficient. Local authorities were clearly prepared for such scenarios, and there was no sign of panic among the population.”
Andrés Morales, chief scientist at the Chilean Oceanographic Institute, commented,
“This region is geologically sensitive, with high tsunami potential. With an earthquake of this magnitude, it is imperative that we consider tsunami risks seriously and act with utmost caution.”
Aftershocks Expected, Travelers Advised to Stay Alert
Carlos Valdivia, director of the Chilean National Seismology Center, noted that aftershocks are common following such a powerful quake and that the region could experience additional tremors in the coming days. While these are expected to be weaker, the public should stay vigilant.
Authorities in both Chile and Argentina have requested residents to stay updated with official announcements, keep emergency kits ready, and ensure mobile phones remain fully charged.
Special advisories have also been issued for tourists, urging them to avoid travel to affected areas. Some tourist activities have been temporarily suspended, according to travel agencies.
Officials indicate it may take several days for the situation to stabilize, and in the meantime, all safety measures should be strictly followed.
