People likely experienced weak shaking there. Many smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of Mexico, Mexico City, 815 km (506 mi) away from the epicenter, the earthquake could not be felt.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry59 km (37 mi)NE of epicenterEl Arenal(pop: 1,160)III: WeakAcapetahua, Estado de ChiapasMexico68 km (42 mi)E of epicenterFrancisco I.

It has had at least 6 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 20 to 25 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
