Secondary hazards from an underwater earthquake, producing powerful waves
How are tsunamis formed?
When there is an underwater earthquake along a subduction zone, the energy released lifts the sea floor, displacing the water above and forming tsunami waves
What are the main impacts of tsunamis?
Since they travel several miles inland, they destroy land and infrastructure, wash away the soil, and change the landscape
How can tsunamis be predicted?
By using the DART system, which uses sensors to monitor changes in sea level and pressure
How is the DART system used to warn people of tsunamis as they happen?
When tsunami waves are detected, the sensor sends the mesage to tsunami warning stations via a satellite, allowing people to be warned about the tsunami
