Over the past 30 days, Argentina has recorded 3 earthquakes of magnitude 2.5 or greater in our tracker. 1 reached magnitude 5.0 or higher. 2 landed between M4.0 and M4.9. By depth: 3 intermediate (70–300 km). 2 of the epicenters were offshore. Focal depths ranged from 136.0 km to 180.7 km. All 3 solutions have been reviewed by a USGS seismologist.
Leading the list is a magnitude 5.1 event near 103 km NNW of Villa General Roca, Argentina at 136.0 km depth. The second-ranked event, at magnitude 4.5 near 44 km S of Castro Barros, Argentina, trails by 0.6 magnitude units — a meaningful gap that makes the leader clearly dominant in energy release. Rounding out the top three is a magnitude 4.1 earthquake near 108 km E of Caucete, Argentina.
