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

 a)  75km (47mi) WSW of Cantwell, Alaska

 b)    189km (117mi) NNW of Knik-Fairview, Alaska

 c)  219km (136mi) N of Anchorage, Alaska

  1.  e)  846km (526mi) WNW of Whitehorse, Canada

Location Uncertainty: 
3.0 ml
63.172°N, 150.368°W
± 0.3 km
112.3 km
± 0.4 km
Number of Phase Applied1

Minimum Distance2

Travel Time Residual3
0.56 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)
