Bu fayda bir depremsellik s\u00f6z konusu de\u011fil. Son batimetride Avc\u0131lar ve Beylikd\u00fcz\u00fc\u2019nde denizden gelen bir s\u0131rt var ve bu s\u0131rtta hi\u00e7bir fay izi yok. Olan fay da Kumburgaz \u00e7ukurunda bitiyor. Buradaki fay\u0131n derinli\u011fi 10 kilometre oldu\u011fu i\u00e7in de orada en fazla 6.5 b\u00fcy\u00fckl\u00fc\u011f\u00fcnde bir deprem meydana gelir. Son Silivri depreminden sonra Kumburgaz \u00e7ukurundaki fay \u00fczerinde olu\u015facak stres y\u00fckleme en fazla 6.5\u2019tir. Bunun da meydana gelme olas\u0131l\u0131\u011f\u0131 ise y\u00fczde 3\u2019t\u00fcr.

Ancak bu art\u00e7\u0131lar hi\u00e7bir zaman Adalar fay\u0131 \u00fczerinde meydana gelmedi. Tam tersi bunlar o fay\u0131 keserek kuzeye do\u011fru gelen hatlarda olan depremlerdi. Dolay\u0131s\u0131yla art\u00e7\u0131lar 1999 depreminde sonra o hat \u00fczerinde meydana geldi. Marmara denizinden \u00e7\u0131k\u0131p, kuzeye do\u011fru giden ikincil faylar da var. Nitekim bu faylar ancak Yalova\/\u00c7\u0131narc\u0131k ana fay faaliyete ge\u00e7ince etkin hale gelebilir\u201d \u015feklinde konu\u015ftu.<\/p>\n

Bug\u00fcn ise bu projeye kar\u015f\u0131 \u00e7\u0131k\u0131yorlar. B\u00fcy\u00fck deprem olacak diye bir \u015fey yok. Jeolojik olarak bak\u0131ld\u0131\u011f\u0131nda Kanal \u0130stanbul, ge\u00e7ti\u011fi b\u00f6lgede depremi tetiklemez. Bu kanal hatt\u0131n\u0131n bulundu\u011fu kesimde zemin, ceylan kire\u00e7 ta\u015flar\u0131ndan olu\u015fuyor ve g\u00fcneye g\u00f6re (B\u00fcy\u00fck\u00e7ekmece-Avc\u0131lar- Beylikd\u00fcz\u00fc) daha sa\u011flam. Ancak o b\u00f6lgede yer yer heyelanlar g\u00f6r\u00fclebilir. Heyelan\u0131n d\u0131\u015f\u0131nda kuzey-g\u00fcney gidi\u015fli faylar 1984 depremi gibi bir deprem olursa bu b\u00f6lgede tetiklenebilir.

1999 y\u0131l\u0131nda meydana gelen K\u00f6rfez depreminin y\u0131k\u0131c\u0131 etkisinin en b\u00fcy\u00fck nedenini binalar\u0131n yap\u0131m\u0131ndaki yanl\u0131\u015fl\u0131klar ve eksiklikler oldu\u011funu kaydeden Beykent \u00dcniversitesi Rekt\u00f6r Yard\u0131mc\u0131s\u0131 Prof. Dr. Mehmet Emin Karahan ise konferansta yapm\u0131\u015f oldu\u011fu a\u00e7\u0131l\u0131\u015f konu\u015fmas\u0131nda \u015fu ifadelerde bulundu:<\/p>\n
\u201cBu depremde binlerce insan\u0131m\u0131z\u0131 kaybettik. \u00c7ok can ve mal kayb\u0131 oldu. Bu deprem sonras\u0131nda b\u00f6lgeyi birka\u00e7 kez gezdim. \u00d6yle yanl\u0131\u015fl\u0131klar yap\u0131yoruz ki bunlar\u0131n cezas\u0131n\u0131 \u00e7ekiyoruz. Mesela Adapazar\u0131\u2019n\u0131n oldu\u011fu yer al\u00fcvyon arazi ve zemin \u00e7\u00fcr\u00fck. E\u011fer deprem olmasayd\u0131 bir- iki hafta sonra oradaki binalar\u0131n kat y\u00fcksekliklerini belediye meclisi karar\u0131yla iki-\u00fc\u00e7 kat daha art\u0131racaklarm\u0131\u015f. Bu belediye meclisinin verebilece\u011fi bir karar de\u011fil. Bu teknik bir konudur. Bu zemin be\u015f kat yerine yedi kat ta\u015f\u0131yorsa \u00e7\u0131kar\u0131l\u0131r, yoksa \u00e7\u0131kar\u0131lmaz. Bu depremden sonra birinci kattan sonra yap\u0131lan \u00e7\u0131kmalar\u0131n binalar\u0131n y\u0131k\u0131lmas\u0131n\u0131 kolayla\u015ft\u0131rd\u0131\u011f\u0131 da g\u00fcndeme gelmi\u015fti.
