| 1. | Small tremors had been shaking the place for four days , but that was in the norm , too 已经连续四天小地震频频,但这也是很正常的事。 |
| 2. | What you want is a series of little earthquakes that relieve the pressure over time , not the big one 这些小地震是七国集团财长在迪拜会议上释放的。 |
| 3. | The result is consistent with the characteristics of disaster of moderate earthquakes 研究结果与近年来湖南中南部地区发生的中小地震的高震害特征比较吻合。 |
| 4. | A number of accelerograms obtained in small and moderate earthquakes can be used for the " blind prediction " studies 已经获取的一批中小地震近场记录可以用来进行盲测研究。 |
| 5. | The world is in a situation akin to sitting at the fault line between two tectonic plates straining against each other 当今世界处于一种两阵对垒极度向对方施压的局面。现在需要一系列小地震来舒缓长期紧绷的应力。 |
| 6. | In this paper , for the application of stochastic simulation of ground motion , we put forward a method of determining the parameters of path and site using digital seismic data of small - moderate earthquakes 摘要本文从强地面运动随机模拟方法应用出发,提出了一种用中小地震的数字观测资料确定研究区路径、场地参数的方法。 |
| 7. | Because the data used in these studies are mainly from the large earthquakes , magnitude greater than 5 . 5 , these results are not very suitable for the estimation for the small - moderate earthquakes 由于这些研究所使用的资料的震级与距离的范围均较大,且一般以大震为主要研究对象,其结果对近源中小地震动参数( m5左右)估计的可靠性相对较差。 |
| 8. | The nearly conical fuji is classified as a dormant volcano since it last erupted in 1707 , but the government was rattled in november 2000 when the number of small earthquakes shaking the peak jumped to more than 200 from a monthly average of around 20 这座类似圆锥形的火山最后一次爆发是在1707年,之后被归为"休眠火山" 。但是在2000年11月,日本政府大伤脑筋,因为富士山上小地震不断,从平均每月20次左右飙升到200次之多。 |
| 9. | In this paper , based on the method of spectral analysis and the theory of fracture mechanics , by using the broad - band digital data recorded by xi an telemetry seismic network , the stress drop and regional shear stress of moderate and small earthquakes in shanxi province are determined firstly 利用西安数字地震遥测台网记录的宽频带数字地震资料,应用断裂力学理论与谱分析方法,首次测定了陕西地区中小地震的应力降和区域剪切应力值。 |
| 10. | The records we used are mainly from three parts : strong ground motion data before 1992 ' s ; data from scec ( south california earthquake catalog ) ; nsmp ( national strong motion project ) . after we developed the attenuation laws , we analysis the attenuation characteristics for the pga and sa with different damping ratio . here we mainly concentrate on the effect of the distance and the magnitude 在回归出中小地震的衰减关系后,本文对峰值加速度(水平向与垂向) 、加速度反应谱(阻尼比分别为0 . 005 、 0 . 02 、 0 . 05 、 0 . 1 、 0 . 2 )的衰减特性进行了分析,影响因素主要考虑了震级与距离这两个方面。 |
