Roughly 11 million people exposed to shaking

This earthquake may have been felt by around 11 million people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

An estimated 122,000 people were exposed to level V. At this level, moderate shaking and very light damage can be expected. Intensity level IV was experienced by the majority of people (around 9 million). In their region, light shaking and likely no damage can be expected.

People in 2 countries have been exposed to shaking. In Chile , around 11 million people, with impact levels up to V (moderate shaking, very light damage). Shaking was experienced by inhabitants of Argentina too.

50 Aftershocks detected

This main shock was followed by 50 smaller aftershocks. A 4.9 magnitude earthquake hit 13 mins later 15 km (9 mi) north of this earthquake.

Before this earthquake struck, 7 smaller foreshocks occurred. A 4 magnitude earthquake hit 19 hrs earlier nearby.

Overview of foreshocks and aftershocks

More earthquakes coming?

Aftershocks are usually at least 1 order of magnitude less strong than main shocks. The more time passes, the smaller the chance and likely strength of any potential aftershocks.

In only six percent of cases, significant earthquakes are followed by a larger main shock, making the current earthquake a foreshock. While the chance of this happening is not so large, it is adviced to maintain cautiousness in the hours and days following a major earthquake.

Earthquakes like this are common in the region

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since February 12th, 2026, when a 6.1 magnitude earthquake hit 232 km (144 mi) further north. An even stronger magnitude 6.9 earthquake struck on April 24th, 2017.

In total, 12 earthquakes with a magnitude of 6 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 10 months.

Low tsunami risk

Based on early data it appears this earthquake was not strong enough (lower than MAG-6.5) to be likely to cause destructive tsunami's. However this earthquake appeared to have hit at a shallow depth under sea, so stay cautious and monitor advice from local authorities.
