What it means
An earthquake of magnitude 4.4 was recorded at a depth of 160 km, near San Antonio de los Cobres, on 16/10 at 21:46 UTC. The data is preliminary and may be updated.
Within 50 km of the epicentre, 2 events were recorded in the last 30 days (maximum magnitude 4.4). It is the strongest quake in the area in the last 30 days. The hypocentre is at intermediate depth, 160 km.
An earthquake in this magnitude range is considered moderate to light. It is often felt by people nearby, but the shaking is usually brief and rarely has significant effects. Because the rupture occurred deep underground, its energy spreads over a wider area before reaching the surface, which typically makes the shaking weaker than that of a shallow event of similar strength. Smaller aftershocks can follow because the surrounding rock slowly readjusts as stress redistributes, a natural process that often produces tremors too small to be noticed. For official guidance and updates, please refer to Protezione Civile and INGV.
It may contain errors: when in doubt, the source figure prevails.
