An earthquake rattled western Colombia and was reported to have been felt all the way in Panama City. The 5.6-tremor hit Medelin at approximately 10:43 a.m. and is reported to be the largest earthquake the country has experienced in six years. The quake was centered 100 kilometers offshore at 6 feet deep, the U.S. Geological Survey said.

Colombia's President Juan Manuel Santos tweeted that the quake was harmless and that there was nothing for residents to fear. There have been no reported deaths, injuries or significant structural damage.The last earthquake of similar size occurred in September 2007, when a 6.8-tremor struck the country's west coast. Jaime Raisgosa told Reuters that the earthquake caused violent shaking, but that was the extent of its effects. The Alaska Tsunami Warning Center, which monitors tsunamis in the Pacific region, said no warnings were in effect for Colombia.
