报告了台湾省实时地震监测的最新进展,特别是中央气象局(CWB)开发的地震速报(RRS)和地震早期警报系统(EWS)的最新进展。该系统利用的是自由场强地面运动仪遥测传输的信号。为地震速报之目的,中央气象局从1995年起在大地震(m> 4级)发生后一分钟之内提供地震烈度图、震中和震级参数,并以电子信息文件形式提供给政府机构和科学家,其可靠性近乎完美,特别是对破坏性大地震而言。利用1999 年集集地震期间收集到的大量数据,得出了一组经验关系式,以此中央气象局能够在大地震发生后的几分钟之内,通过速报系统发布计算出的PGA、PGV和可能的破坏分布情况。这种近实时的破坏评估对震灾快速应急响应和救助行动的展开具有重要作用。快速确定震级是根据自动生成的有效子台网的前10 s记录来实现的。以此为基础,得出一个监测软件,据此我们能够做出30 s之内的地震速报。这是向更实际的地震早期警报迈出的重要一步。从2002年起,该地震早期警报系统已经在中央气象局运行。综合的地震报告大部分能在地震发生之后30 s内发布,平均时间为22 s。当地震发生在距城市不足66 km时由于典型地壳剪切波速为3 km／s,现时的操作系统是无效的,而对于离震源的距离大于100 km的城市来说,前导时间会增加到10 s 以上。在后一种情况下,几秒钟的前导时间将足以使预编程序的应急响应在破坏性强震到达之前启动。

通过计算Z值的标准正态偏差及古登堡—里克特关系中的b值,研究了2003年台湾成功地震(mw=6.8)之前台湾地区地震活动性图像的变化。在成功地震震源周围的Z值分布中可以识别出地震活动的mogi环形变化。在成功地震之前的震源区附近还明显看到b值的下降。相对较低的地震活动速率和b值的下降可能是整个地震活动中与平静相联系并使得成功地震前主震区域中等事件活动加强的前兆现象。

This study aims to develop a chloride diffusion simulation method that considers the hydration microstructure and pore solution properties during the hydration of tricalcium silicate(C3S).The method combines the hydration simulation,thermodynamic calculation,and finite element analysis to examine the effects of pore solution,including effect of electrochemical potential,effect of chemical activity,and effect of mechanical interactions between ions,on the chloride effective diffusion coefficient of hydrated C3S *** results indicate that the effect of electrochemical potential on chloride diffusion becomes stronger with increasing hydration age due to the increase in the content of hydrated calcium silicate;as the hydration age increases,the effect of chemical activity on chloride diffusion weakens when the number of diffusible elements decreases;the effect of mechanical interactions between ions on chloride diffusion decreases with the increase of hydration age.
