Step-by-step explanation:
If an earthquake occurred near the oceanic trench in this figure, the hazard that is likely to threaten the town of Ashton is a tsunami. Earthquakes near the sea have the potential to trigger tsunamis, which are large ocean waves that can cause destruction to coastal regions. An example of this is the earthquake off the east coast of Japan in 2011, which generated a tsunami that caused widespread devastation along the coast and even affected nuclear energy facilities.
