At what type of plate tectonic setting is an earthquake most likely to generate a tsunami explain your reasoning?
The most powerful of these natural hazards occur in subduction zones, where two plates collide and one is thrust beneath another.
Which type of tectonic setting are tsunamis most common at?
Tsunamis are most common in the Pacific Ocean Basin. The entire Pacific Ocean is ringed by areas known as subduction zones, where the tectonic plates of the earth are moving relative to one another. Subduction zones are where two or more plates are colliding and one is going underneath another.
Where are earthquakes most likely to create tsunamis?
Most tsunamis are generated by shallow, great earthquakes at subductions zones. More than 80% of the world’s tsunamis occur in the Pacific along its Ring of Fire subduction zones.
How do tectonic plates cause earthquakes and tsunamis?
Earthquakes that generate tsunamis most often happen where Earth’s tectonic plates converge, and the heavier plate dips beneath the lighter one. Part of the seafloor snaps upward as the tension is released. … The falling debris displaces the water from its equilibrium position and produces a tsunami.
How do earthquakes occur at convergent plate boundaries?
Convergent plate boundaries
The plates move towards one another and this movement can cause earthquakes. … This happens because the oceanic plate is denser (heavier) than the continental plate. When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth’s surface.
What is an earthquake and how do earthquakes generally occur quizlet?
An earthquake is a ground shaking caused by the sudden and rapid movement of one block of rock slipping past another along fractures in the Earth’s crust, called faults. Most large earthquakes occur when there are huge amounts of stored energy in the rocks that suddenly is released (as seismic waves).
Compression within a plate causes the crust to deform without breaking. Folds are bends in rock that form when compression shortens and thickens Earth’s crust. … Stress makes rock and earth’s surface move. The large movement cause earthquakes and earthquakes cause landslide and or ocean floor uplift which cause tsunamis.
