A cyclone and tidal wave
have visited the island of Leyte, which is one of the Philippine group,
and have done a great deal of damage, sweeping over a vast tract of
country and killing thousands of people.
A tidal wave, or, more properly speaking, an earthquake wave, is an
extraordinarily high wave, supposed to be formed by the disturbance
caused by an earthquake in the bed of the sea.
The action of the earthquake causes the waters to retreat from the
shores, and gather themselves into a mighty mass, which suddenly turns
and advances upon the shore in one huge wave of enormous height. This
wave sweeps on over the land until it has spent its force, when the
waters rush back to the sea once more.
The force of such a wave is so great that it destroys everything in its
path, tearing up rocks and boulders, and carrying them along inland with
it.
In 1746, when the coast of Peru was the scene of one of these
catastrophes, a war-ship was lying at anchor in one of the bays. The
wave came sweeping down upon it, lifted it up on its crest and bore it
several miles inland, depositing it on the side of a hill.
The island of Leyte, which has just been visited by one of these
terrible waves, is one of the smallest of the Philippine group.
