Webfind focal mechanism solutions for the other earthquakes in the cluster and investigate whether this solution is a rule or merely an exception. The 1982 swarm focal mechanisms are very similar to the solutions of the 2001 sequence. Chiu et al., (1984) calculated composite focal mechanism for 6 different Webfocal mechanisms as a function of magnitude, location, and kinematics of seismic source and consequently their reliability in defining seismotectonic models. To study the consistency of focal mechanism solutions, we use a Bayesian approach that jointly inverts the P/S long-period spectral-level how to share an ibook i purchased
