但是，如果扰动影响的地区很大，象强烈地震所能做到的，那末所产生的地震海浪运动好象沿直线产生而不是在一点产生。

But if the disturbance affects a large area, as a great earthquake can, the resulting seismic sea waves nay behave as if they had been generated along a line rather than at a point.

地热异常、地壳内存在低速层和高导层、强烈地震频繁发生等现象说明，这一地区是现代构造运动的活动区。

The geothermal anomaly, low velocity zone and high conductivity layer in crust, and frequent occurrence of strong earthquakes show that the study area is an active area of modern tectonization.

信浓川地震带位于日本大地沟北部，地壳运动十分强烈，区内地震主要沿信浓川流域发生，并密集成带，大地构造上处于日本海板块向本州板块俯冲的边界线上。

The Shinanogawa seismic belt, which is developed in the Northern Fossa Magna, Honshu Island, Japan, extends along the Shinano River bounding the Eurasian Plate and the Okhotsk Plate.
