Homes damaged and roads buckled by series of shocks including the biggest on record in US stateEarthquakes of up to 5.6 magnitude have shaken Oklahoma, damaging buildings and roads and sending a handful of people to hospital.
The first quake was recorded on Saturday morning at a magnitude of 4.7. The second came on Saturday night and is the largest recorded in Oklahoma, topping a tremor of 5.5 magnitude in 1952, according to the US Geological Survey.
In Prague, Oklahoma, where the first quake was centred, city manager Jim Greff said part of the town library's ceiling collapsed and a chimney fell through the roof of a home. There were no serious injuries.
The quake buckled highway 62 in three places west of Prague and sent a boulder "about the size of an SUV" tumbling onto a rural road in south-east Lincoln County, said Aaron Bennett, dispatch supervisor for the county's emergency management division.
