Japan tunnel disaster: Weak bolts suspected, other tunnels probed
December 4, 2012
Ageing bolts could be to blame for the deadly collapse of a tunnel west of Tokyo, a highway maintenance executive told reporters on Monday after nine people lost their lives to the weekend disaster. Tons of concrete panels tumbled onto cars in the Sasago tunnel on Sunday morning, crushing and trapping vehicles underneath. The disaster stunned a nation that relies heavily on tunnels to navigate its steep terrain and has been credited as a leader in tunnel safety.
The Los Angeles Times interviewed Dr Fathi Tarada of Mosen Ltd on his views of the disaster. The interview can be viewed here.
