What are the causes and effects of tsunami?
Tsunami are waves caused by sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.
How fast do Tsunamis travel?
The deeper the water, the faster the tsunami. In the deep ocean, tsunamis can move as fast as a jet plane, over 500 mph (800 km/h), and can cross entire oceans in less than a day. The distance between waves is the wavelength.
What happen before tsunami?
An earthquake is a natural tsunami warning. … Witnesses have reported that an approaching tsunami is sometimes preceded by a noticeable fall or rise in the water level. If you see the ocean receding unusually rapidly or far it’s a good sign that a big wave is on its way. Go to high ground immediately.

Most tsunami waves are less than 10 feet (3 meters).
What happens when a tsunami hits land?
Just like other water waves, tsunamis begin to lose energy as they rush onshore – part of the wave energy is reflected offshore, while the shoreward-propagating wave energy is dissipated through bottom friction and turbulence. …
How does a tsunami start?
A tsunami is a series of ocean waves caused by any large and sudden disturbance of the sea surface. Tsunamis can be generated by landslides, volcanic eruptions, or even meteorite impacts in the ocean. But they are most often caused by an earthquake where there’s a sudden displacement of the ocean floor.
