Turkish undersea railway earthquake warning system
According to International Railway Gazette, the control centre for the new Marmaray rail tunnel linking the European and Asian part of Istanbul will receive earthquake information from the Kandilli Early Warning System. The railway runs under the Bosphorus in a very earthquake prone region. The trains will be automatically stopped by the control centre when an earthquake warning is received. The tunnel is equipped with flexible joints and flood gates to protect against earthquakes. Last year I visited the Kandilli Observatory and Earthquake Research Institute, at Bogazici University who run the earthquake warning system for Turkey and looked at their warning system and discussed how to use new technology to get emergency information out quickly. The Institute provides a very valuable service.
