震中的

The amended results are: the name of this historieal earthquake is suggested to be Yanqing Haituo Mountain earthquake in Beijing; its occurrence time is in September of 294; its magnitude is estimated to be 6 and the epicentre to be at (115.83°E, 40.59°N) with a location accuracy of grade Ⅱ.

校订后的结果是：地震名称应为北京延庆海坨山地震，发震时间为公元294年9月，震级为6级，震中位置为115.85°E、40.59°N，震中误差为Ⅱ类。

He has designed more than 30 types of safety equipments, including a low cost earthquake alarm, an epicenter direction finder and an epicenter distance locator.

他已经设计了30多种安全装置，包括一个低成本的地震报警仪，一个震中方向确定议，以及一个震中距离确定仪。

According to the iso-intensity line roughly delineated,it is co njectured that the epicenter location should be moved 110 km to east (at 20°N, 114.1°E),and based on the statistical result of the maximum distance from the epicenter location to isoseismic line with intensityⅤ, the magnitude M S=7.1 of this earthquake determined by Xujiahui observatory in Shanghai should be more reasonable.

由大致 勾画的等烈度线图推测，其震中位置应从现定微观震中向东推移110 km(20°N，114.1°E)。参考我国6 3/4～7 1/2级地震的震中位置与V度等震线最远距离的统计结果，认为上海徐家汇观象台将该震定为7.1级是较为合理的。

Two earthquakes of M S 6.0 and M S 5.8 occurred on Jan. 3,1994 and on Feb. 16,1994 in Gonghe county of Qinghai Province. The macroseismic epicenter of the Gonghe M S6.0 earthquake was at Hongqi village of Heka town, 7km south to the Tanggemu farm. The intensity at the epicenter was Ⅷ. 9 people were slightly injured during the event. The direct economic loss was 57.4486 million Yuan.

1994年1月3日、2月16日在青海省共和县发生6.0级和5.8级地震，6.0级地震的微观震中为36.07° N 、100.16° E ，宏观震中位于塘格木农场南部约7km 的河卡乡红旗村牧业点，震中烈度Ⅷ度；5.8级地震的微观震中为36.13° N 、100.17° E ，宏观震中位于塘格木农场北东约21km 处的沙珠玉乡上卡力岗村，震中烈度Ⅶ度1）。

The Yumen earthquake of Ms5.9 occurred on Des.14,2002 in Yumen city of Gansu Province,with instrumental epicenter at 39°49ˊN,97°20ˊE;The macroseimic epicenter was located westsouth of Yumen city 26 kilomite.The meizoseismal area was elliptic with major axis in NW direction and intensity Ⅶ.

据甘肃省地震台网测定， 2002 年 12 月 14 日 21 时 27 分，在甘肃省玉门市境内发生了 M s 5.9 级地震，微观震中为 39 ° 49 ˊ N ， 97 ° 20 ˊ E ，宏观震中位于玉门市窟窿山-赤金峡一带，在微观震中南西 12km 处的祁连山内，震中烈度Ⅶ度，震源深度为 22km ，玉门市处在Ⅵ度区内。

Saturday's quake was centeredoffshore an estimated 21 miles (34 kilometers) underground in a relatively unpopulated area while Haiti'stectonicmayhem struck closer to the surface -- about 8 miles (13 kilometers)-- and right on the edge of Port-au-Prince.

智利这次地震，震中在海下21英里，周边地区人口不多，而引起大面积建筑物倒塌的海地地震，震中更靠近地面——地下6英里——而且就在太子港不远处。

The results show that two earthquake epicenters are located in the vicinity of declination and inclination zero line.

结果表明：（1）两次震中均位于岩石圈磁场的磁偏角和磁倾角零值线附近；（2）震后震中百公里范围内岩石圈磁场分量均出现了不同程度的异常变化；（3）震中附近岩石圈磁场出现了明显的与地震相关的变化，该变化在两个震区表现出相近的规律性。

"As mentioned by Bak in this debate, the SOC hypothesis has been suggested, on the one hand, on the basis of the observation of power law distributions, such as the Gutenberg-Richter law for earthquakes and the fault length distribution, and of the fractal geometry of sets of earthquake epicenters and of fault patterns, and on the other hand on the study of highly simplified models with somewhat similar scale-invariant properties."

&如同Bak在这场辩论中已提到的那样，一方面，在对动力法则分布进行观测的基础上，如用于地震和断层长度分布的Gutenberg-Richter定律，以及对震中的破裂几何学内容的观测和对断层图案的观测，以及另一方面对带有某种程度类似标度不变性质高度简单的模型的观测基础上，提出了SOC〔'自组成危险性'〕假说。&
