Magnitude 3.4 Earthquake of Kodiak, Alaska 2014-09-17

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

 a)  130km (81mi) SSE of Kodiak, Alaska

 b)    503km (313mi) S of Anchorage, Alaska

 c)  538km (334mi) SSW of Knik-Fairview, Alaska

 d)  918km (570mi) SSW of Badger, Alaska

  1.  e)  1026km (638mi) W of Juneau, Alaska

Location Uncertainty: 
3.4 ml
56.765°N, 151.363°W
± 1.1 km
0.1 km
± 0.8 km
Number of Phase Applied1

Minimum Distance2

Travel Time Residual3
0.75 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)
