It struck with magnitude of 6-point-7 as people slept, injuring several people after their buildings partially collapsed.
The Department of Foreign Affairs says its embassy in Athens is monitoring the situation to see if any Irish people have been caught up in the disaster.
Christopher Hackland has been working as a diving instructor in Kos for the last two months.
"There were pots and pans crashing around the kitchen. The light was swining and crashing off the ceiling. It was hard to walk as well. It was almost as if we were very, very dizzy."
