Magnitude 5.3 Earthquake of Little Sitkin Island, Alaska 2014-09-10

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

 a)   23km (14mi) NW of Little Sitkin Island, Alaska

 b)    1331km (827mi) E of Petropavlovsk-Kamchatskiy, Russia

 c)   1348km (838mi) E of Yelizovo, Russia

 d)   1349km (838mi) E of Vilyuchinsk, Russia

  1.  e)   2961km (1840mi) W of Whitehorse, Canada

Location Uncertainty: 
5.3 mb
± 0.03
52.111°N, 178.297°E
± 1.3 km
121.3 km
± 4.9 km
Number of Phase Applied1

Minimum Distance2
107.3 km (0.96°)

Travel Time Residual3
0.79 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)
