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 felt2247–279 km (153–174 mi)263 km (163 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.Compare Quake DataData for the same earthquake as reported by different agenciesThe more agencies report about the same quake and post similar data, the more confidence you can have in the data.

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 3 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 3 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Sep 16, 2025 06:29 pm (GMT -6)26 minutes ago4.55 km0 km - This quakeOff Coast of EcuadorMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 25 years and our earthquake archive back to 1900, there are about 1.2 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 5 or higher: 0.04 quakes per year (or 1 quake every 25.6 years)Mag. 4 or higher: 0.36 quakes per year (or 1 quake every 2.8 years)Mag. 3 or higher: 0.5 quakes per year (or 1 quake every 2 years)Mag. 2 or higher: 0.5 quakes per year (or 1 quake every 2 years)The area where this quake occurred has very few earthquakes and most of them are very small (below magnitude 3). Larger quakes with magnitudes above 3 might occur from time to time. However, It has had at least 19 quakes above magnitude 4 since 1970, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 1 to 5 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeStrongest in 4 yearsThe earthquake was the strongest to hit this part of Ecuador in over 4 years.
