Question 2

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 B, C, and D. These are the Spanish-controlled Canary Islands off the Northwest coast of Africa. The second image is of the volcanic island of La Palma near the ocean, which in addition to being active, has very steep sides that some worry could cause a subaerial landslide.
