My chosen country is Germany. Several fault lines run through this country, including: the Karsdorf fault, the Lusatian fault, and the Rhine Rift Valley. The Lusatian fault is a "Thrust fault" which means part of the earth shoves lowers layers of earth upwards. The Rhine Rift Valley is a "rift zone" where fissures split the volcanic earth that could allow lava to flow out. When it comes to hazards, Germany has a high rate of extreme storms. Flooding and extreme temperature change also factor into hazards for the country. Part of Germany's population lives relatively close to a volcano.
The Holocaust could be considered an extreme catastrophe for Germany in a sense, since millions were killed (though it was a catastrophe caused by humans, not nature).
