摘要
利用2005—2009年福建GPS基准站资料,解算了各测站20期的季速度场,结合近年福建及其周边大地震,分析了福建地区速度场变化特征。结果表明,2007年南海地震发生时段,福建各测站的速度场发生明显变化,反映了福建地区速度场受菲律宾板块运动的影响。
Based on GPS base station data in Fujian area from 2005 to 2009,velocity fields of twenty stages are calculated and analyzed combined with strong earthquakes in Fujian and the surrounding area.The result shows that the velocity fields of Fujian area changed obviously during the occurrence of the South China Sea earthquake in 2007,which indicates that the velocity fields is affected by the Filipinas plate.
