The new seismic hazard analysis model is based on the magnitude and the interval of earthquake and the epicentral distance.
以地震震级、震中距和时间间隔的统计概率规律为基础,建立了考虑地震发生的时空不均匀性且不需要事先假定确定的地震发生模型和根据大量区域地震地质资料划分潜在震源区的地震危险性分析模型。
For pass through the low velocity zone,the S wave of earthquakes with epicentral distance of 9°~36° are weak,so the LG wave are used to determine the epicentral distance of the earthquake in shadow area of S wave.

汶川地震滑坡的分布特点及最大震中距分析
Based on the above results,we analyzed the residual distribution with azimuthe and epicenter distance,discussed,from the viewpoints of the equilibrium of nonstatic forces and the earth surface structure,the reason why those residuals exist,and proposed the average correction for different regions,by which the precision of event locations can be improved.
在此基础上分析各台所记录的所有地震事件的残差随方位角和震中距的分布，及产生这些残差的地球深部非流体静力平衡状态和地球表面构造等方面的原因，并给出了不同区域地震走时的平均校正值，从而提高了地震定位精度。
It is discovered that the capacity is connected with eathquake magnitude or epicenter distance and spread along a line.
研究宝坻台Sacks钻孔体应变仪的地震响应能力,发现它与震级及震中距有关,即体应变地震波振幅与震级和震中距的数理统计关系是随震级增大呈指数增加、随震中距增大呈幂函数衰减;分析了京津地区6台Sacks体应变仪在多次地震发生时,震时应变阶的响应特征,显示其极性(压、张)与观测点所在断层有一定关系。
Compared with the original definition, the influence of rupture length on RTL function is emphasized and the weights of epicentral distance function, time function, and rupture length function are ensured to be equal.
引入并改进了“区域 时间 长度算法”(region time lengthalgorithm) ,较之原来的定义更加强调了地震破裂尺度函数对VRTL的贡献 ,同时保证了震中距函数、时间函数及破裂尺度函数对VRTL影响的权系数相等 。
