Abstract
A brief summary is given of four more extensive reports, dealing with the problem to locate microearthquakes and to determine their focal mechanism. Methods and computer programs are developed for the solution of these problems by means of initial P waves recorded at small three-dimensional geophone arrays of the general size of 1-3 km. For realistic crustal models, tests indicate that the hypocenter can be determined with errors less than 100 m and the mechanism with average errors of 2° for strike, 4° for dip and 5° for slip with arrays of six to eight geophones. Detailed knowledge of the local crustal structure is of crucial significance in order to achieve an acceptable accuracy.
