In context

How big was it, and why here?

Energy released

15 kilotons of TNT

That is about the energy of the Hiroshima bomb. It released about 32 times the energy of a magnitude 5.0.

Tectonic setting

97 km

from the nearest mapped plate boundary, between the Nazca and Altiplano plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.

Depth: shallow

27 km

Shallow earthquakes (under 70 km) produce the strongest surface shaking for their size, so they are the ones most likely to cause damage near the epicenter.

Did You Feel It?

Where it was felt

Reports sent by people to USGS, grouped by place (most reports first). Intensity uses the Modified Mercalli scale (I–X): what people felt, not the magnitude.

After the main event

Aftershocks within 100 km

USGS lists 21 M2.5+ earthquakes within 100 km in the following 30 days; the largest was M7.2 on June 28, 2024. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
