Question 5

Based on what you can see, which of the following could be causes of tsunamis in this image? (Choose all that apply.)

Click on red boxes to zoom-in. There may be more or fewer correct answers than there are zoom-ins.

a) Subduction zone earthquakes

b) Subaerial landslides

c) Submarine landslide

d) Volcanic eruption

e) Strike-slip fault next to a high-profile submarine feature

f) None of the above

The correct answers are A, B, C, and D. These are the Aleutian Islands in southwest Alaska. A subduction zone with a steep dropoff lies nearby, and volcanoes dot the islands. Steep-sided inlets are found on the south side. As a result, subduction zone earthquakes, submarine landslides, volcanoes, and subaerial landslides are possible tsunami causes in this area.
