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

a) 435km (270mi) W of Waldport, Oregon

b) 447km (278mi) WNW of Coos Bay, Oregon

c) 494km (307mi) W of Dallas, Oregon

d) 498km (309mi) W of Corvallis, Oregon

e) 517km (321mi) W of Salem, Oregon

Number of Phase Applied1

Minimum Distance2
460.08 km (4.13°)

Travel Time Residual3
1.43 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)
