Members of the Turkish civil defence corps work inside the wagon of a derailed train during a drill by city authorities for a possible earthquake in Istanbul in this November 7, 2006 file photo. Turkey lies on a major fault line and has had 90 earthquakes higher than magnitude 5 since 1903, including one in August 1999 when nearly 18,000 people were killed. Of those deaths 1,000 were in Istanbul, and many were blamed on sub-standard buildings thrown up by a construction industry rife with corruption. To match feature TURKEY-EARTHQUAKE/
