现代地壳应力值高,构造变形速度快,地震活动强度加剧,地热流异常明显。
Present crustal stress values are high, structural deformation rate is fast, intensity of earthquake has an obvious increasing trend, and terrestrial heat flow anomaly is very obvious.
Vidale说:但是这些研究所能做出的预测仅限于底层活动所导致地震的频率以其强度,而不能预测出任何一个单一的地震事件的发生。
But such hazard predictions can go only so far, Vidale says. They can warn how often and how strongly the ground will shake, but they can't forecast the magnitude of any single event.
指出区内的地震活动范围、位置、强度和深度受前寒武纪结晶基底的起伏构造形态和深度的影响与制约。
The study shows that the range, location, intensity and depth of earthquakes are effected and restricted by the rolling topography of Precambrian crystal basement.
影响黄土地区地震崩滑敏感性的宏观因素包括活动地质构造、地震断层、地层、地形、水文条件、地震强度等。
The macroscopic factors influencing sensitivity of seismic loess landslides include geological structure, seismic fault, stratum, topography, hydrological condition, seismic intensity etc.
震例计算表明,该指标能够反映区域地壳的背景活动强度,对中强地震亦具有较强的敏感性。
The calculating results shows that the index can reflect background active strength of regional crust, and is sensitive to medium strong earthquakes.

The calculating results shows that the index can reflect background active strength of regional crust, and is sensitive to medium strong earthquakes. It has some applying value.
并根据未来地震活动和强度、震害地质条件以及历史震害分布规律,将工作区划分为六个震害区;
The hazard of strong earthquakes in history indicates that its distribution has a close relation to geological conditions.
20世纪云南地区地震活动以极高的频度、强度和成灾率而位居我国大陆之前列。
The seismicity in yunnan region in the20th century occupies a front place in Chinese mainland in extremely high frequency strength and hazard rate.
腾冲火山区的微震活动分布、地震强度、及震源深度特征所表现的现象可能与地下岩浆体活动相关,显示了与火山热物质孕震机理有关的明显特征。
Therefore, the features of distribution of microseisms, magnitude and depth are probably related to the activity of magma body, which show mechanism of hot volcanic matter.
高R值强转折梯度带很可能是岩石层的剧烈变形带,多对应于地震高强度、高频度活动区;
An abrupt gradient zone with higher R values may be a radical deformed zone of the lithosphere , it mostly corresponds to an seismic active region with higher intensity and frequency;
指出在大震孕育过程中的区域地震活动迁移过程,可能与区域介质强度或原有断面“闭锁”“粘结”程度存在差异有关。
The migration process might be related to the difference of the medium strength in the different areas, and to the degree of locking on the different fault surfaces.
