How can human protect themselves from a tsunami?

To protect themselves from a tsunami, humans should first be aware of tsunami warnings and evacuation routes, often indicated by signs in coastal areas. It's crucial to move to higher ground immediately if a tsunami warning is issued, as the first wave may not be the largest. Additionally, individuals should avoid staying near the coast and refrain from returning until authorities confirm it is safe. Preparedness also involves having an emergency kit and a communication plan in place.
