Explanation:

Question 7

In wave terminology, the highest point of a wave (including a tsunami wave) is called the crest, and the lowest point is called the trough.

A local tsunami is one that is generated close to the coast (in this case, 12 kilometers offshore) and impacts the nearby coast within a few hours. A distant tsunami would be generated far away (e.g., across an ocean basin). A volcanic tsunami is caused by volcanic activity (not indicated here as the cause is an earthquake). A seismic megatsunami is a very large - scale tsunami (magnitude - wise, not indicated by the 12 - kilometer distance).

Answer:

crest, trough
