A strong earthquake off the west coast of Costa Rica has prompted a tsunami warning, US officials said. The US Geological Survey later downgraded the strength of the earthquake to 7.6 magnitude from an earlier estimate of 7.9. The quake occurred at 1442 GMT about eight kilometres north-east of Samara and 151 kilometres west of the capital San Jose. No one was immediately reported injured, the Red Cross said, and damage caused by the quake in Costa Rica was believed to be relatively minor.
