If you have to be inside one, pick a hurricane. But tornadoes are so much smaller. This list is like... 10-20 per year with an average of less than 1 casualty and a dozen houses damaged? That's basically zero as far as insurance and habitability go. I found a study titled "Tornadoes in Europe An Underestimated Threat" and it has an estimate of 10-50 million euros per year in total damage. That's not even 1 euro per house in Europe.
