A Jamaican man who found himself caught in the grip of a 7.4-magnitude earthquake in Colombia says chaos erupted in the stairwell of the 17-storey hotel where he was staying, as panicked guests rushed to the exits amid “terrifying” tremors. Dave Creary said he arrived in Medellín on Saturday for a one-week vacation and was sleeping in his room when an earthquake alert on his cell phone went off early Monday morning. He said that seconds later, at approximately 7:30 a.m., his hotel room on the 12th floor began shaking violently, causing him to run for the exit.
