Magnitude 3.2 Earthquake of Prudhoe Bay, Alaska 2014-09-14

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

a)  138km (86mi) S of Prudhoe Bay, Alaska

b)   464km (288mi) N of College, Alaska

c)  466km (290mi) N of Fairbanks, Alaska

d)  470km (292mi) N of Badger, Alaska

  1. e)  1103km (685mi) NNW of Whitehorse, Canada

Location Uncertainty: 
3.2 ml
69.020°N, 147.902°W
± 1.6 km
7.9 km
± 0.5 km
Number of Phase Applied1

Minimum Distance2

Travel Time Residual3
0.55 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)
