According to the Titan research project, which specializes in the analysis of regional policy, 77 billion Euros can be attributed to losses connected to natural disasters. 

From1995 to 2017, floods, storms, droughts and earthquakes have had negative economic impacts in the European Union with a resulting drop in gross domestic product, causing almost 77 billion Euros in damage, of which 43.5 billion Euros directly linked to natural disasters, and 33.4 billion Euros stemming from the economic links with the areas hit by natural disasters. 

The numbers are timely, as Western Europe is going through the aftermath of massive flooding that has killed at least 195 people in Germany and Belgium.
