Which following earthquake is most likely to generate a powerful tsunami?

What is the strongest wave of a tsunami?

Lituya Bay, Alaska, July 9, 1958

Its over 1,700-foot wave was the largest ever recorded for a tsunami. It inundated five square miles of land and cleared hundreds of thousands of trees. Remarkably, only two fatalities occurred.

What type of plate boundary is most likely to generate a tsunami?

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 kind of fault is most likely to result in 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 following would be the most likely to create a tsunami?

Tsunamis are caused by violent seafloor movement associated with earthquakes, landslides, lava entering the sea, seamount collapse, or meteorite impact. The most common cause is earthquakes.

What type of earthquake is likely to lead to a tsunami?

The earthquake must be a shallow marine event that displaces the seafloor. Thrust earthquakes (as opposed to strike slip) are far more likely to generate tsunamis, but small tsunamis have occurred in a few cases from large (i.e., > M8) strike-slip earthquakes.

What type of earthquake causes a tsunami?

Usually, it takes an earthquake with a Richter magnitude exceeding 7.5 to produce a destructive tsunami. Most tsunamis are generated by shallow, great earthquakes at subductions zones.

What type of plate boundary is earthquakes?

About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.

How tsunami is formed after an earthquake?

Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. When large areas of the sea floor elevate or subside, a tsunami can be created. … Large vertical movements of the earth’s crust can occur at plate boundaries.
