Becky said: "We were about to leave to head back to our hotel when the ground started shaking beneath us - it almost felt like a stampede was coming.
"After a few seconds the buildings, lamp posts, furniture all starting collapsing with one building completely crumbled, crushing loads of people that were stood outside that bar.
"After the initial earthquake there was great panic of a Tsunami, hundreds of people screaming and running away from the beach.
"At this point I lost my friend Rachel as she got trampled by the crowds. We found each other shortly after and were advised to find a high place if possible.
"After an hour we headed to the main square where hundreds of people were injured and crying. Many had packed their suitcases ready to get off the island as soon as they can.
"We slept on the streets as the tremors were strong and often. Today walking around Kos town we could see the full extent of the damage."
Becky's dad, John Kelly, of Scorton, told of his relief to learn the pair were safe after speaking to them this morning.
He said: "They only went last week to work. She said they thought they were going to die.
"There was panic everywhere and a guy covered in blood. Luckily they weren't hurt."
Becky and Rachel are due to fly back to the UK on Tuesday.
