How do scientist Measure tsunami

scientist measure tsunami by sensing pressure changes at the bottom of the ocean (as water depth increases, pressure increases).

How do volcano erupted  

When enough magma builds up in the magma chamber as it forces its way up to the surface and erupts.

How do Seismologists study earthquakes  

By looking at the damage that was caused and by using seismometers.

400

How are tornadoes form

when hot air meets cold air 

400

what has to happen for a tsunami to be big enough to cause a lot of damage

The amount of movement of the ocean floor, the size of the area over which it occurs (which may be reflected in how long the earthquake lasts), and the depth of the water at its source

400

Where is the volcano kilauea located 

Hawaii

How much damage can a hurricane cause when its a category 5

 Fallen trees and power poles will isolate residential areas that can cause power outages 

500

what are the plates called that causes earthquakes

tectonic plates

500

How many tornadoes does  the U.S predicted every year

1,200

How do underwater earthquakes create tsunami

If big enough and close enough to the ocean floor, the energy from such an earthquake can cause the ocean floor to suddenly rise (uplift) or fall (subside). This sudden vertical displacement of the ocean floor is what typically sets a tsunami in motion. As the ocean floor rises or falls, so too does the water above it.
