SIMULTANEOUS INVERSION OF EARTHQUAKE HYPOCENTERS AND VELOCITY STRUCTURE (I)—THEORY AND METHOD

摘要: Abstract In this paper, the problem of simultaneous inversion for earthquake location and velocity structure is discussed, difficulties encountered in are discussed. After separation parameters from hypocentre parameters, introduction an orthogonal projection operator has made system equations consistent. Thus, it possible to obtain a unique solution classical sense through appropriate distribution seismograph network. With respect numerical values, suggested that adoption methods matrix block sequential triangularization can save computer storage. If simultaneously combined with equivalent models rapid procedure ray tracing, practicability joint be unproved.
