FAQ

Common questions

Can every earthquake cause a tsunami?

No. Tsunami potential depends on location, depth, fault movement, seafloor displacement, and other factors. Use official tsunami warning centers.

What are natural warning signs?

Strong or long coastal shaking, unusual sea withdrawal or rise, or a loud ocean roar can be warning signs in some areas. Follow local education and official instructions.
