Directions and Distances :Directions and Distances from Geographical Reference in Close Proximity Which can be effected by Location Uncertainty

a) 55km (34mi) NNE of San Felipe, Chile

b) 63km (39mi) N of Los Andes, Chile

c) 65km (40mi) ENE of La Ligua, Chile

65km (40mi) SE of Salamanca, Chile

e) 132km (82mi) N of Santiago, Chile

Location Uncertainty: 
4.8 mb
± 0.07
32.264°S, 70.575°W
± 27.5 km
79.9 km
± 9.2 km
Number of Phase Applied1

Minimum Distance2
89.1 km (0.80°)

Travel Time Residual3
1.32 sec

Azimuthal Gap4

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)
