DESCRIPTION

Dünya standarlarinda haritalar 2007 ve 2009 yıllarında İstanbul için bitirilmiş fakat kullanılmıyor. Kullanılan harita 1996 yılında yapılmış ve yasal Türkiye Deprem Tehlikesi Haritası. Yıllar süren çalışma ve emek sonunda İstanbul için hazırlanan haritanın kullanılacak şekilde yasal statü kazanmaması, depreme dayanıksız yapılaşmaya neden oluyor. Çelişkili durum düzeltilmeli.
