Interactive remote rock-burst monitoring and on-line analysis system can provide real-time monitoring of microseismic signals in the process of coal mining.It is able to analysis and prediction of rock-burst disaster online,which makes the coal mining safe and efficient,and reduces injuries and property losses due to the rock-burst disasters.The system is build by JSP and SQLserver using B/S structure.The client of the system does not require any additional software,and can finish all the operation through the web browser.The system is divided into five major functional modules according to the logical function which include update and display module,analysis and display module,mining parameters and figure setting module,advancing parameters input and early-warning module,data processing to empty and update module.The update and display module to update and show the latest tremor space-time distribution chart.Analysis and display module is used to show any time period with different energy of tremor space-time distribution.The advancing parameters input and early-warning module is used to add,delete advancing parameters every day,and based on the current dangerous situation submit the early-warning prompt and consultation opinion of the expert group.The personnel of coal mine,and expert group for prevention and control of the rock-burst all can access the system through the browser,view the latest tremor space-time distribution and identify risk in advance.The expert group members determine the dangerous situation every day,and timely submit early-warning prompt and opinion,thus people on coal mine can timely take measures to control rock-burst.

对南北地震带地区发生的强震进行了系统的回溯性震例研究，并利用“区域技能评分”方法对预测结果进行了效能评估。结果表明，地震“丛集率”方法对南北地震带地区6.5级以上具有较高的预测效能。当变换预测的目标地震震级，统计检验结果显示，对南北地震带地区，最佳预测的目标地震震级为6.5级。进一步考察地震“丛集率”方法的最佳预测时间尺度，对南北地震带地区系统的回溯性研究和利用“区域技能评分”方法检验结果表明，最
本文通过基于遥感影像解译，通过对龙门山中段盆山分界地带的构造地貌详细调查，发现沿断层表现为山前线性洪积台地的前缘陡坎，通过探槽发现断层表现为逆断，断错了晚第四纪地层的证据;断错地貌的RTK测量表明山前洪积台地陡坎高10.2±1.4m，年代测试结果表明山前洪积台地的年龄为-28ka，从而表明龙门山中段山前断裂的晚第四纪垂直滑动速率0.36±O.O5mm/a。布设的浅层地震勘探与收集到的石油勘探资料也

改革开放36 年来，中国7 级以上大地震主要发生在青藏高原地区，且大多位于无人区。根据中国大地震成组活动时空演化规律，东部城市群地区发生7 级以上大地震的危险性在不断升高。随着城镇化进程的加快，人口、财富和产业持续不断地向城市群地区聚集。三分之一以上的已建或拟建的城市群位于可能会发生7 级以上大地震的地区。城市群地区如果没有充分的备灾措施，一旦发生7 级以上大地震，就会对国家安全和社会稳定造成巨大
