                              1Number of phase Applied: 
                              In determining location of hypocenter, applied number of observations on P waves and S waves. The greater the more accurate prediction of EQ.

                              2Minimum Distance:
                               Horizontal distance of nearest Station measured in Km from epicenter. The smaller the more accuracy in prediction of depth of EQ.

                              3Travel Time Residual:
                               A way of measurement of fit of arrival time observed to arrival time predicted for particular location. The smaller the better fit of data.

                              4Azimuthal Gap: 
                              Expressed in degree; the smaller the smaller the error in horizontal positioning of EQ. Large uncertainty is considered when exceeds 180° (both depth and location)
