AbstractTwo methods are developed for relating the direction of polarization of S waves to the .mechanism at the focus of an earthquake. Application to three or four earthquakes for which the fault-plane solutions from P waves were previously available show that in these cases the S wave data agree with the P wave solution and conform to a dipole with moment as the model of the focus. In three Kamchatka earthquakes the same methods of analysis indicate a new type of focus, represented by a single force.
