Which of the following fault movement beneath the sea will not produce tsunami?
To generate tsunamis, earthquakes must occur underneath or near the ocean, be large and create movements in the sea floor. A strike-slip fault where the movement of adjacent plates is primarily horizontal is not likely to cause a tsunami.
Which of the following fault movements can generate a tsunami?
Earthquakes generally occur on three types of faults: normal, strike-slip, and reverse (or thrust). Tsunamis can be generated by earthquakes on all of these faults, but most tsunamis, and the largest, result from earthquakes on reverse faults.
Which of the subsequent fault movements will lead to tsunami?
Tectonic subduction and tectonic plate boundaries are the areas most likely to cause tsunamis. … When thrust faults move abruptly a tsunami can be generated when associated with destructive or convergent plate boundaries. This is because of the vertical component of movement and abrupt displacement.
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.
What caused tsunamis?
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 are the 3 fault types?
There are three main types of fault which can cause earthquakes: normal, reverse (thrust) and strike-slip.
How tectonic plates cause a tsunami?
Subduction. 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.
