Tsunamis and landslides are not rated for a single city here. Climate risk profile of Turkey
An earthquake's shaking at İzmit can reach 4.33 m/s², as strong as a once-in-475-years event.
Istanbul: 2.15 m/s².
İzmit's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, İzmit is projected to have the climate that Rome (Italy) has today.
+1.5°C
Mean temperature over the year
+2.2°C
Highest in the warmest month
+1.2°C
Lowest in the coldest month
-7%
Precipitation over the year
Under high emissions, İzmit would have the climate that Rome (Italy) has today.
Share this comparison
How close the match is: 0.1 σ to the climate of Rome today, where under 2 is close and over 4 is no match (Mahony et al. 2017). 3 of 3 climate model runs name the same city. Seasonal temperature and rain are compared, not extremes, city heat or the sea.
Hazards at İzmit
Read at the city's centre and compared with the Atlas's 630 large cities. Moderate emissions is the IPCC's scenario SSP2-4.5.

Flood depth is read in a single 1 km cell at the city's centre, in today's climate. Other parts of the city can still flood. The country page names the deepest point near a coastal city in 2080, so its figure can be higher. See how deep a river flood reaches around İzmit on the live map
