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

a) 182km (113mi) WSW of Bella Bella, Canada

b) 284km (176mi) S of Prince Rupert, Canada

c) 336km (209mi) SSW of Terrace, Canada

d) 430km (267mi) WNW of Campbell River, Canada

e) 641km (398mi) NW of Victoria, Canada

Location Uncertainty: 
6.2 mww
51.769°N 130.695°W
± 7.0 km

± 1.8
Number of Phase Applied1

Minimum Distance2
183.68 km (1.65°)

Travel Time Residual3
0.85 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)
