A M6.1 earthquake struck the Tarapaca-Antofagasta border in Chile on January 2, 2025, at a depth of 99 km. The USGS issued a green alert, indicating a low likelihood of fatalities due to the region’s generally resilient infrastructure. Approximately 169,000 people experienced moderate shaking, while 442,000 felt light tremors.
On January 2, 2025, at 20:43 UTC, a significant earthquake measuring M6.1 occurred in the Tarapaca-Antofagasta border region of Chile. The United States Geological Survey (USGS) reported that the quake struck at a depth of 99 km (61 miles), while the European-Mediterranean Seismological Centre (EMSC) noted a depth of 91 km (56 miles). The epicenter was situated approximately 85 km (53 miles) north-northwest of Calama and about 118 km (74 miles) east-northeast of Tocopilla, two towns within the Antofagasta region.
Chile is positioned along the Pacific Ring of Fire, rendering it susceptible to seismic activity. The Tarapaca-Antofagasta region has experienced numerous earthquakes due to the interaction of tectonic plates. Seismic events here can result in significant shaking, which poses risks of landslides and damage, primarily to vulnerable structures. While buildings in the area are generally resistant to earthquakes, traditional adobe and stone masonry constructions remain susceptible to severe shaking.
In summary, the M6.1 earthquake that struck the Tarapaca-Antofagasta border region of Chile is a reminder of the seismic volatility in this tectonically active area. While the USGS projected a green alert for potential shaking-related fatalities and economic losses, the likelihood of significant damage is low due largely to the resilience of local infrastructure. Continued monitoring and research are essential to understand and mitigate future earthquake impacts.
