Magnitude 3.5 Earthquake of Ferndale, California 2014-09-07

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

  1. a) 69km (43mi) W of Ferndale, California

  1. b) 78km (48mi) W of Fortuna, California

  1. c) 80km (50mi) WSW of Eureka, California

  1. d) 89km (55mi) WSW of Arcata, California

  1. e) 382km (237mi) NW of Sacramento, California

Location Uncertainty: 
3.0 md
± 0.12
40.613°N, 125.086°W
± 5.9 km
0.1 km
± 15.2 km
Number of Phase Applied1

Minimum Distance2
75.3 km (0.68°)

Travel Time Residual3
0.56 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)
