海底地震

海洋中经常发生海底地震。

Submarine earthquakes often happen in ocean .

海啸（或称津浪，tsunami）是海底地震（海震）、火山爆发等因素引发的巨浪。

Tsunami is a billow induced by the earthquake and volcanic eruption in the sea bottom .

而使用海底地震仪（OBS）进行广角反射地震测量，可较好地解决高阻抗层屏蔽问题，它是开展海上地质构造勘查的一种行之有效的方法。

Wide angle reflection seismic survey is a useful method to solve the problem .
