Based on an automated impact model, this earthquake, which occurred in a region with low vulnerability to natural disasters, has potentially a low humanitarian impact.

Whether international humanitarian aid is needed must be decided by an expert.

The population in the area of this earthquake is 92 people/km?.

The earthquake occurred at 10h local time. At this time a day, more people are at work and therefore more vulnerable to collapsing office buildings. During traffic hours, people can be affected by collapsing bridges and other road infrastructure.

Resilience and Vulnerability

Resilience is the capacity of the population to cope with a hazard. Since much of investments in earthquake preparedness and available funds for quick response is related to household income, the GDP per capita can be used as a rough indicator of resilience.

Turkey has a GDP per capita of 2964 PPP$ (Parity Purchasing Power Dollar, about 1 Euro) and is therefore part of the low level income countries. Therefore, the earthquake happened in an area of low resilience.

Based on the combination of 9 indicators, ECHO attributes Turkey a low vulnerability.

Secondary effects

Probability of secondary effects:

Landslides: The maximum slope in the area of the earthquake is 38.255% and the maximum altitude is 1725 m. Since this is a medium slope, the risk of earthquake induced landslides is medium. Note, however, that the slope data is not reliable on a local scale, while landslides depend very much on local topography, soil and meteorological conditions. Nuclear power plants: There are no nuclear facilities nearby the epicenter. Hydrodams: The following hydrodam installations are near the epicenter: Gediz (167km)
