查询词典 seismic activity

The idea is that, in the event of a collapse, survivors able to reach one of the plates would bash it to create vibrations that are detected by a string of geophones, standard devices used to measure seismic activity, placed on the surface along the line of the mine.

The Italian geophysicists are concerned that the same period coincided with the most intense seismic activity ever recorded in the area.

意大利地球物理学家关注的是，同一时期，正值最激烈的地震活动有纪录以来在该地区。

In this paper,the relations between isostatic gravity anomaly in Fen-Wei fault depression zone,surfacial tectonics,crustal stracture, neotectonic movement and seismic activity are discuseed.

本文研究了汾渭断陷带均衡重力异常分布特征与地壳表、浅层结构，新构造运动和现代构造运动，以及均衡重力异常与地震活动性之间的关系。

Based on these results, we analyzed seismic activity along subsurface faults and within crust, lateral variations of velocity anomalies at different depths and their relations with geological tectonics, crustal anisotropy of the mantle anomalous area beneath the west Tien Shan and possible dynamic mechanism.

以此为基础，我们分析了浅表层断裂和地壳深部的构造活动、不同深度速度异常的横向变化与重要地质构造的关系、天山西部地幔异常区地壳深部的各向异性特征和可能的深部动力机制等。

Our result suggests that the very low Pn velocity beneath the southcentral Tien Shan is caused by high temperatures produced by heating from mantle upwelling, and that this heat has been conducted up into the crust, inducing a ductile rheology that prevents significant seismic activity.

这一现象说明地幔上涌引起高温极大地降低了岩石层地幔的强度，并以热传导的方式进入地壳使其失去地震破裂强度而发生韧性变形。

There is a clear correlation between seismic activity and Pn velocity variation. Most earthquakes are concentrated in the northcentral Tien Shan with high Pn velocities, while almost no earthquakes located in the southcentral Tien Shan with very low Pn velocities.

Pn波速度的变化与地震分布有着密切的对应关系：地震大都发生在中天山北部Pn波高速区上方，而南部的Pn波低速区上方几乎没有地震。

Taiwan is located between Eurasia plate and Philippine Sea plate and its seismic activity is frequent.

中国台湾地区地处欧亚板块与菲律宾海板块之间，地震活动频繁。

Scientists discovered 10 years after the Hoover Dam was built in 1935 that its reservoir was increasing seismic activity.

美国的胡佛大坝于1935年建成，科学家们在大坝建成10年后发现，水库增加了地震活动。
