　　本文概述了2001年昆仑山口西Mw7.8、2003年北海道十胜冲Mw8.3、2004年苏门答腊Mw9.2、2008年汶川Mw7.9、2010年智利Mw8.8、2011年日本东北近海Mw9.0和2012年苏门答腊Mw8.6地震等在北京房山岩体附近即时触发小震活动的波形分析结果.并基于首都圈地区数字测震台网和部分流动地震台的观测资料，以统一原则重新读取远震动态触发事件的震相到时，利用Hypoinverse-2000程序得到约束明显改善的重定位结果，结果表明动态触发事件都发生在房山岩体附近，主要集中在岩体西边的强变形带中.结合研究区的背景地震活动等资料，综合分析表明应力加载是北京房山岩体附近触发地震活动的主要因素，但研究区的特殊构造环境特征等其它因素也有所贡献.
