The month's largest event in Argentina was a magnitude 7.5 earthquake near Ushuaia, Argentina on 02 May 2025 at 12:58 UTC. A magnitude 7.5 earthquake radiates roughly 2.7 million tons of TNT equivalent in seismic energy.

That is well above the Argentina monthly average of 18 events over the period we cover — an unusually active month, and up from the 10 recorded the previous month.

80% of events here are shallow (under 70 km), 20% intermediate (70–300 km) and 0% deep-focus (over 300 km). The mix is dominated by shallow crustal events, with a minority of intermediate-depth activity.
