Oaxaca (192.7 km W of epicenter) [Map] / Light shaking (MMI IV) : We were on a balcony of a restaurant and it began shaking. At first we thought it was a semi truck going by but there were no cars at all and it was a bit more shaking than a semi truck would’ve normally caused. | One user found this interesting.
