‘Rigidity on the road’
Sukru Ersoy, a professor of geology at Turkey’s Yildiz Technical College, stated historic information of previous earthquakes means that one on the fault line underneath the Marmara Sea is close to.
“We all know how a lot the North Anatolian Fault line strikes yearly by means of analysis. The motion of the fault line will result in rigidity on the road that can trigger the earthquake,” he instructed Al Jazeera, however added it’s inconceivable to know precisely when it’s going to happen.
Huseyin Alan, chairman of the Chamber of Geological Engineers, agreed: “A magnitude 7.0 or larger earthquake is anticipated in Istanbul in keeping with the info we have now.”
Ersoy defined: “The fault line underneath the Marmara Sea has the capability to create two earthquakes stronger than magnitude 7.0 in a single yr. We noticed this in Kocaeli and Duzce. earthquakes in 1999, in addition to in different ones within the area previously.”
A magnitude-7.6 earthquake hit the western a part of Turkey’s Marmara area in August 1999 and killed 7,500 folks. One other 7.2 hit close by Duzce, killing 845 in November of that yr.

Istanbul will produce 30.4 p.c of Turkey’s gross home product in 2021, in keeping with official datamaking it the center of financial exercise within the nation.
