OKLAHOMA CITY – The Oklahoma Department of Transportation has announced a new program for inspecting the state’s transportation infrastructure and bridges following earthquakes.
ODOT said Thursday inspections will follow earthquakes of magnitude 4.7 or greater. The department said a recent analysis found damage is unlikely from an earthquake of magnitude 4.6 or less.
ODOT will inspect a 5-mile radius from the epicenter of magnitude 4.7 and 4.8 quakes; a 15-mile radius after 4.9 to 5.3 magnitude quakes; a 30-mile radius following 5.4 to 5.8 magnitude quakes; a 60-mile radius after 5.9 to 6.2 magnitude quakes and a 120-mile radius after an earthquake of magnitude 6.3 or greater.
ODOT chief engineer Casey Shell says no structural bridge damage has ever been found in the state related to earthquakes since inspections began in 2013.
