A M6.1 earthquake occurred in the Tarapaca-Antofagasta border region of Chile on January 2, 2025. The quake was recorded at a depth of 99 km by USGS and 91 km by EMSC, affecting approximately 611,000 people. A Green alert was issued, denoting low expectations for casualties and damage due to earthquake-resistant buildings.
On January 2, 2025, a significant earthquake measuring M6.1 struck the border region between Tarapaca and Antofagasta in Chile at 20:43 UTC. The United States Geological Survey (USGS) recorded the quake at a depth of 99 kilometers (61 miles), while the European-Mediterranean Seismological Centre (EMSC) reported it at a slightly shallower depth of 91 kilometers (56 miles). The epicenter was found approximately 85 km (53 miles) NNW of Calama, and 118 km (74 miles) ENE of Tocopilla. An estimated 169,000 individuals experienced moderate shaking, whereas around 442,000 felt light shaking. The USGS subsequently issued a Green alert, indicating a low likelihood of fatalities or significant economic losses, primarily due to the region’s earthquake-resistant infrastructure, despite the presence of some vulnerable structures.
Chile is located along the Pacific Ring of Fire, a region characterized by frequent seismic activity due to the tectonic movements of the Nazca and South American plates. Earthquakes in this area pose various hazards, including potential landslides, particularly following seismic events. The local construction practices include buildings designed to withstand such tremors; however, traditional building types like adobe and stone masonry can be susceptible to seismic shocks. Awareness and preparedness are essential factors in mitigating the impact of these natural occurrences.
The M6.1 earthquake that occurred on January 2, 2025, near the Tarapaca-Antofagasta border highlights the ongoing seismic activity in Chile. With a low alert for casualties and economic loss due to robust infrastructure, the event serves as a reminder of the region’s vulnerability to natural disasters and the need for continued monitoring and research into earthquake preparedness and response strategies.
