Magnitude 2.6 Earthquake of Talkeetna, Alaska 2014-09-12

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

a)  86km (53mi) NNW of Talkeetna, Alaska

b)    180km (112mi) NNW of Knik-Fairview, Alaska

c)  207km (129mi) NNW of Anchorage, Alaska

  1. e)  866km (538mi) WNW of Whitehorse, Canada

Location Uncertainty: 
2.6 ml
63.026°N, 150.829°W
± 0.4 km
118.0 km
± 0.5 km
Number of Phase Applied1

Minimum Distance2

Travel Time Residual3
0.49 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)
