Playa Flamingo Costa Rica (34.5 km NNE of epicenter) [Map] / Light shaking (MMI IV) / single lateral shake / very short : I didn’t realize it was a quake when it happened. But we definitely felt it. We were sitting at the pool in heavy teak lounge chairs. The entire concrete pad and concrete structure of the pool moved. We are on the hillside. We couldn’t figure out what would make the pool and concrete flooring move like it did but it’s obvious now that I know there was an earthquake. | 2 users found this interesting.
