How do tsunamis form and their effects?

Transcript

Tsunamis primarily form due to underwater earthquakes, volcanic eruptions, or landslides that displace a large volume of water. This displacement generates a series of waves that can travel vast distances at high speeds, sometimes exceeding 500 miles per hour in deep water, but can grow significantly in height as they approach shore due to shallower ocean depths. The resulting waves can cause catastrophic flooding, damaging infrastructure, and leading to loss of life when they inundate coastal areas.
