Show Summary Details

Quick Reference

A seismic sea wave of long period, produced by a submarine earthquake, underwater volcanic explosion, or massive gravity slide of sea-bed sediment. In the open ocean such waves are barely noticeable even though they may be travelling at 700 km/h, but on reaching shallow water they build up to heights of more than 30 m and cause severe damage in coastal areas.

Subjects: Earth Sciences and Geography.
