It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!Number of reports by intensityShaking intensityNumber of reportsMin-Max distance from epicenter (*)Average distance (*)I: Not felt1407–407 km (253–253 mi)407 km (253 mi)III: Weak shaking185–85 km (53–53 mi)85 km (53 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (2 in total) could be used for geographic statistics.Get the Android appI didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report!

When aftershocks are detected, we will update this section.What are aftershocks?Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.[More info]What about this quake?Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface area of approximately 2 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 2 km (1 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 21, 2026 01:04 am (GMT -4)33 minutes ago4.224 km0 km - This quakeSouth Pacific Ocean, 96 km W of La Serena, Provincia de Elqui, Region de Coquimbo, ChileMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 475 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.34 quakes per year (or 1 quake every 2.9 years)Mag. 5 or higher: 4.6 quakes per yearMag. 4 or higher: 49 quakes per year (or 4.1 quakes per month)Mag. 3 or higher: 232 quakes per year (or 19.3 quakes per month)Mag. 2 or higher: 475 quakes per year (or 39.6 quakes per month)The area where this quake occurred has a very high level of seismic activity.
