Procjenjuje se da samo u Istanbulu 90% zgrada nije otporno na zemljotrese i da će biti potreban značajan budžet i vremenski period -- skoro 20-25 godina -- da se prilagode sve već postojeće zgrade u gradu.
It is estimated that in Istanbul alone, 90% of buildings are not resistant to earthquakes and a considerable budget and time -- nearly 20-25 years -- would be needed to retrofit all the buildings in the city.
