Earthquake Event Details
A moderate earthquake with a magnitude of 4.8 struck Cordoba Province, Argentina, on Sunday, December 21, 2025. The seismic event occurred at 04:02 AM local time (America/Argentina/Cordoba GMT -3), corresponding to 07:02:23 UTC. The United States Geological Survey (USGS) was identified as a primary data source for this event.
Epicenter and Depth
The earthquake's epicenter was located approximately 110 kilometers (68 miles) northwest of Villa Carlos Paz, within the Departamento de Minas in Cordoba Province. Its geographical coordinates were recorded as 30.953°S latitude and 65.5049°W longitude. The tremor originated at a significant depth of 197 kilometers (122 miles).
Impact and Felt Reports
Despite its moderate magnitude, the earthquake was largely unfelt by residents, with zero reports of shaking submitted. The estimated shaking intensity, according to the Modified Mercalli Intensity Scale, was II (Very weak shaking). This lack of widespread perception is likely attributed to the considerable depth of the hypocenter.
Regional Seismic Context
The Cordoba Province region experiences a moderate level of seismic activity. On average, the area near the epicenter records approximately 1.83 earthquakes of magnitude 4 or higher annually. On the day of the event, December 21, 2025, this 4.8 magnitude earthquake was the sole recorded event of its size in Cordoba Province.

The lack of impact is definitely a positive outcome for residents. However, this event underscores the continuous need for robust seismic monitoring, as a shallower quake of similar magnitude could yield very different results.

Good to see the monitoring systems are working. Important data.
Habibi
Good that this particular tremor caused no alarm due to its depth. Still, it serves as a natural reminder that Cordoba is seismically active, and understanding basic earthquake safety is always a wise precaution.

So glad it was unfelt! Safety first!
Coccinella
It's reassuring that there were zero reports of shaking, indicating no immediate danger. Yet, knowing the area experiences multiple M4+ quakes annually suggests that preparedness and monitoring remain crucial for potential future events.
