Moderate magnitude 4.2 quake hits 58 km east of Tinogasta, Argentina early evening

An earthquake of magnitude 4.2 occurred early evening on Thursday, June 16th, 2022, at 7:02 pm local time near Tinogasta, Departamento de Tinogasta, Catamarca, Argentina, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at an intermediate to considerable depth of 187.7 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.2 earthquake as well. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.2, and the German Research Centre for Geosciences (GFZ) at magnitude 3.9.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Londres (pop. 2,600, 34 km away), La Puerta de San José (pop. 1,100, 48 km away), Tinogasta (pop. 14,500, 58 km away), Arauco (pop. 13,700, 69 km away), Fiambala (pop. 8,100, 72 km away), and Andalgala (pop. 14,100, 79 km away), the quake was probably not felt.
