According to TASS an earthquake with a magnitude of 7.3 was registered in Chile. The country's President Gabriel Boric said that the authorities do not yet have data on casualties or serious damage. "I contacted a representative of the region, and at the moment there are no reports of casualties or serious damage, but specialists continue to collect information," he wrote on X (formerly Twitter). Gabriel Boric added that some cases of rock falls were registered on highways in the region. In addition, a power outage was reported in the village of San Pedro de Atacama. It is known that the cataclysm affected six provinces of the country at once - Tarapaca, Antofagasta, Atacama, Coquimbo, Arica and Parinacota. At least a dozen aftershocks were registered in the hours following the quake, with emergency services reporting a rock fall between the towns of Calama and Tocopilla, forcing authorities to close roads.

Focal mechanism solution of the origin was calculated by GS RAS with signs of initial arrivals of P waves at 80 stations, including 25 stations which registered compression waves (plus signs), and 55 stations which registered tensile waves (minus signs). The stations are located in the interval of epicentral distances 0.4-98.3º and in azimuth sector Az=3-357º. Focal mechanism solution in stereographic projection on the lower hemisphere and elements of the mechanism are presented in the table. The table also contains focal mechanism solutions obtained at the USGS NEIC with WW-phase Moment Tensor (Mww) technique and in Lamont-Dohert Earth Observatory of Columbia University, USA (LDEO GCMT) with СМТ (Centroid moment tensor) technique. Solutions from different centers are close. The earthquake occurred under prevailing action of tensile stresses oriented E-NE (AZ=66-74º). One nodal plane NP1 strikes S-SE (STK=165-167º) according to GS RAS and LDEO GCMT and S (STK=172º) according to USGS NEIC, another plane NP2 strikes N-NW (STK=332-344º). NP1 lies more horizontally (DP=20-24º) if compared with NP2 (DP=66-71º). The type of motion along NP1 – gentle fault, along NP2 – normal fault. The seismic moment according to USGS NEIC makes Mo=1.444*10**20 N*m, Mww=7.4. according to LDEO GCMT it makes Mo=1.24*10**20 N*m, Mw=7.3.
