Tsunami Instigators
What are two causes of tsunamis that you remember?
What is earthquakes, volcanic eruptions, submarine landslides, large ocean-asteroid impacts, and coastal rockslides
Which of the faults can Earthquakes occur on?
What is all of them!
What are constantly moving and shifting along Earth's surface?
What is tectonic plates
Where does the Earthquake that is most likely to cause a Tsunami occur?
What is a subduction zone
What is the general minimum magnitude for an Earthquake in the ocean to cause a tsunami?
What is 7.0
What is the main cause of tsunami formation?
Earthquakes deep in the sea
What are the three types of faults?
Reverse faults, normal faults, and strike-slip faults
Where do tectonic plates meet?
What is plate boundaries
In what direction(s) does the tsunami form and travel?
What is all directions outward from the center of the earthquake under the sea
What is the approximate maximum depth that the earthquake must occur below the surface of the ocean to cause a tsunami?
What is 100 km

What is earthquakes, volcanic eruptions, submarine landslides, large ocean-asteroid impacts, and coastal rockslides
Where generally is there most likely to be an earthquake?
What is faults
Why does pressure build up in the Earth's crust over time?
What is the shifting plates catching and locking
What causes the sea floor to actually get raised and create a tsunami?
What is the overriding tectonic plate in the collision breaking free upwards
Which fault do most Earthquakes occur on?
What is the reverse fault
The build-up of pressure between the plates causes energy to release in what form?
What is Shaking and cracking to form faults
