腾冲火山区地表垂直形变分析
ANALYSIS OF VERTICAL DEFORMATION IN TENGCHONG VOLCANIC AREA
【摘要】 对腾冲火山区 1998~ 2 0 0 0年的 3期垂直形变资料进行了分析 ,进而利用相关资料得出与计算有关的参数 ,再用多元Mogi模型反演了岩浆房的位置和大小 ,所得出的结果与地震层析反演结果基本相似。分析反演结果 ,认为火山区可能存在多个岩浆房 ,并有岩脉相通
【Abstract】 The measured data (from 1998 to 2000 )of the vertical deformation in Tengchong volcanic area is analyzed and then some related data is used for obtaining the parameters for calculation.The magma position and size are inversed with Mogi poly model and the least square method.The result implies that there are several magma chambers underground and they may be connected by magma veins or sills. The result is close to that obtained by using a seismic computerized tomography.
