DISASTROUS TIDAI WAVES

—r —. , ■; ' SHIP THROWN OVER BRIDGE ' ‘' ' , A big ship on her way. across the Atlantic recently was suddenly jarred all over as'tf struck a reef. two other vessels, each about 60 miles from the first, hrid had equally alarm-/ ing experiences. Theh the captain kriew that what he had felt- was the shock from a submarine earthquake or yolcanic explosion. , Sometimes these under-sea earthquakes throw up vast waves, wrongly galled “tidal” waves. Oflßthfc Chilean coast in November, 1922, a wave was so great that it flung a large ship in,land over a railway bridge. The shocks may cast up islands. In 1831 an ilsand of this: sort rose in the Mediterranean, only to sink qgain; while in September,,'l9ol, an island rose and vanished in the Gulf of Mexico. 1 t . one of k th<! frequent results of these submarine earthquakes is * die breaking of telegraph cables. 1 tW yearly bill for this sort bf thing runs into many thousands of pounds.
