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)
