Which is worse a earthquake tsunami or a tornado?

Tsunamis are generally more deadly. Earthquake-resistant buildings can help alleviate the impact of an earthquake. You can hide underground when tornado occurs. However, you have to run for high ground during a tsunami, and that takes time.

The severity of a natural disaster really depends on how many people are affected. If a tsunami hits an island with only 20 inhabitants, it is less severe than an earthquake affecting Jakarta, with over millions of inhabitants.
