About the focal mechanism solution of Fanxian ML 4.2 earthquake in Henan Province on Jan 18, 2015
摘要
Abstract
Inverting the ML 4.2 earthquake focal mechanism solution in Fanxian county, Henan Province in 2015.1.18 by CAP method, we come to conclusions: The optimum focal mechanism solution was gained at the focus depth of 9 km, and the moment magnitude (MW) is equal to 4.0. One pitch surface's strike is 66 degree and its dip is 83 degree and its slide angle is -171 degree. Those of the other pitch surface are 134.9 degree, 81.1 degree and -7.1 degree. The data reveal that both belong to strike-slip fault which is as well the result of P-wave first motion method and Snoke method. The strike coincides with the direction of Liao-Lan fault in this region, implying certain correlation between earthquake and Liao-Lan fault activity.关键词
