People likely experienced weak shaking there. Several smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking.

So far, we have received 2 reports for this quake from Ecuador. The quake was reported to have been felt in up to approx. 120 km (75 mi) distance.Most reports came from Santa Elena, a town with 42,000 inhabitants in 111 km (69 mi) distance northwest of the epicenter, Ecuador, and Playas (48 km or 30 mi to the north), a town with 31,000 inhabitants in Provincia del Guayas.

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 (*)II: Very weak shaking146–46 km (29–29 mi)46 km (29 mi)III: Weak shaking1115–115 km (72–72 mi)115 km (72 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!

Your contribution is valuable to earthquake science and seismic hazard analysis.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. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.MagDepthTime GMT2026-10-4EpicenterAgency4.539 km24 mi08:57:19Peru-Ecuador Border RegionRaspberryShake (RaspberryShake)Aftershocks for this quakeNo aftershocks have been recorded so far. 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)Oct 4, 2026 03:57 am (Guayaquil)17 minutes ago - felt4.539 km0 km - This quakeProvincia del Guayas, 44 km NW of Machala, Provincia de El Oro, EcuadorMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 56 years and our earthquake archive back to 1900, there are about 44 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 62.5 years)Mag. 6 or higher: 0.05 quakes per year (or 1 quake every 20.8 years)Mag. 5 or higher: 0.83 quakes per year (or 1 quake every 1.2 years)Mag. 4 or higher: 14.5 quakes per yearMag. 3 or higher: 42 quakes per year (or 3.5 quakes per month)Mag. 2 or higher: 43 quakes per year (or 3.6 quakes per month)The area where this quake occurred has a high level of seismic activity. It has had at least 2 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 60 to 65 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
