Major tsunami from Pacific subduction zones can occur as often as every few hundred years.

Question

Quizplus · Accepted Answer

Major tsunamis in the Pacific, particularly those generated by subduction zones where tectonic plates converge, can indeed occur on a timescale of every few hundred years. This is due to the accumulation and sudden release of stress along these plate boundaries, leading to significant underwater earthquakes that can generate tsunamis. Historical records and geological evidence support this frequency of occurrence.
