Tidal Wave Has Nothing to Do With the Tides

Tidal wave has nothing to do with the tides. Any great onrush of the sea that overwhelms the land is called a tidal wave. Such waves may be due to vartods causes. They may represent a heaping up of masses of water by a hurricane of wind; or an earthquake under the sea may be the cause. Submarine volcanic eruptions are of not very infrequent occurrence, and earthquakes are liable to nnrnmpnny them .Dr a mere Sllpping of strata in the sea floor may cause earthquakes. If. incidentally to the volcanic or seismic disturbance, one part of the sea floor sinks or another part rises there must be a consequent rush of water, which may assume the proportions of what is called a tidal wave. -
