Magnitaude 3.4 Earthquake of Bandon, Oregon 2014-09-29

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

a) 252km (157mi) WNW of Bandon, Oregon

b) 262km (163mi) W of Coos Bay, Oregon

c) 335km (208mi) W of Roseburg, Oregon

d) 350km (217mi) WSW of Corvallis, Oregon

e) 380km (236mi) WSW of Salem, Oregon

Location Uncertainty: 
3.4 ml
± 0.07
43.630°N, 127.443°W
10.0 km
± 2.0 km
Number of Phase Applied1

Minimum Distance2
266.5 km (2.39°)

Travel Time Residual3
0.84 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)
