Minor Tremor in Salta Province
A magnitude 2.5 earthquake was registered in Salta Province, Argentina, on Saturday, October 18, 2025, at 02:49 am local time (GMT -3). The seismic event occurred at a moderate depth of 180 kilometers. According to initial reports, the weak tremor was not felt by the local population and no damage has been reported.
Seismic Details and Location
The epicenter of the earthquake was located approximately 203 kilometers (126 miles) west of Salta city, within the Departamento de Los Andes in Salta Province. Its precise coordinates were recorded at 24.25°S latitude and 67.33°W longitude. The European-Mediterranean Seismological Centre (EMSC) was among the first to report the event, with data also provided by the Departamento de Geofisica, Universidad de Chile, and the Instituto Nacional de Prevención Sísmica (INPRES) of Argentina.
Context of Seismic Activity in the Region
Salta Province is known for its significant seismic activity, experiencing an average of approximately 1,100 earthquakes per year with magnitudes above 2. Earthquakes of magnitude 2.5 or less are generally recorded by seismographs but are typically not felt by humans. Furthermore, the considerable depth of 180 kilometers plays a crucial role in mitigating the impact of seismic waves on the surface. The strength of ground shaking diminishes significantly with increasing distance from the earthquake's source, meaning a deep earthquake is less likely to be felt or cause damage compared to a shallower one of the same magnitude. Damage from earthquakes usually begins to occur at magnitudes above 4 or 5.
No Reported Impact
Consistent with the characteristics of a weak, deep earthquake, there have been no reports of injuries or property damage following this event. Authorities continue to monitor seismic activity in the region, which is a routine occurrence in this geologically active part of Argentina.

A 2.5 earthquake? My cat jumping off the couch makes more impact.

Routine, but important to stay informed about seismic activity.

Waste of time reading about a non-event. Get some real news.

Why is this even news? So utterly insignificant.
