After this tragedy, the Turkish government introduced new building codes and a compulsory earthquake insurance system. However, many of the buildings affected by this week’s quake were built before 2000, says Mustafa Erdik, a civil engineer at Boğaziçi University, Turkey.
Things are worse in Syria, where more than 11 years of conflict have made building standards impossible to enforce. The earthquake struck Syria’s northwestern regions, with buildings collapsing in Aleppo and Idlib. Some war-damaged buildings in Syria have been rebuilt using low-quality materials or “whatever materials are available”, says Rothery. “They might have fallen down more readily than things that were built at somewhat greater expense. We’ve yet to find out,” he adds.
