Which global locations suffer the most or worst natural hazards?
Where are some of the most extreme examples?
Or what locations have great potential dangers?
Like Lake Kivu near the Congo that holds trillions of cubic feet of methane gas that could erupt and kill 2 million people.
I know pretty much every region has a risk of natural hazards, but what are some interesting places with many risks (risk to humans, the environment or anything)?
