A magnitude 4.7 earthquake struck Argentina at 07:02 UTC on 28 October 2026, at a depth of about 186 km, according to a GDACS green alert. The alert estimated 150 thousand people live within 100 km of the epicenter. No damage, injuries or deaths are reported. The alert classed the event at green level, the lowest tier of its alert system. Because the quake was deep, shaking at the surface is typically weaker than for shallow quakes of the same magnitude, though the excerpts give no shaking reports for this event.
