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)
