What fault is more likely to trigger a tsunami?

What is the most common trigger of a tsunami?

Most tsunami are caused by large earthquakes on the sea floor when slabs of rock move past each other suddenly, causing the overlying water to move. The resulting waves move away from the source of the earthquake event.

At what type of plate boundary are tsunami most likely to be triggered?

Most large tsunamis occur at convergent plate boundaries where two tectonic plates are crashing into each other. As the two plates collide one plate is forced down underneath the other.

What caused tsunami?

What causes tsunamis? Most tsunamis are caused by earthquakes on converging tectonic plate boundaries. … However, tsunamis can also be caused by landslides, volcanic activity, certain types of weather, and—possibly—near-earth objects (e.g., asteroids, comets) colliding with or exploding above the ocean.

What type of fault is the San Andreas Fault?

strike-slip fault – a fault on which the two blocks slide past one another. The San Andreas Fault is an example of a right lateral fault.

Which type of fault is least likely to generate a tsunami?

A strike-slip fault where the movement of adjacent plates is primarily horizontal is not likely to cause a tsunami. The San Andreas Fault in California is an example of a strike-slip fault.

Who is responsible for tsunami?

A tsunami is a series of large waves generated by an abrupt movement on the ocean floor that can result from an earthquake, an underwater landslide, a volcanic eruption or – very rarely – a large meteorite strike. However, powerful undersea earthquakes are responsible for most tsunamis.

Where is the fault most likely located in an area struck by a tsunami?

Every coastal area and river estuary is potentially threatened by tsunamis, but they are most likely to happen on shores facing directly a megathrust.

What is a normal fault?

Normal Faults: This is the most common type of fault. It forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture. Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming.
