Region :Inyokern, California

Magnitude 3.1 Earthquake of Inyokern, California 2014-09-20

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

a)  45km (28mi) N of Inyokern, California

b)  50km (31mi) NNW of Ridgecrest, California

c)  103km (64mi) N of California City, California

104km (65mi) E of Porterville, California

Location Uncertainty: 
3.1 ml
± 0.20
36.051°N, 117.861°W
± 0.3 km
0.1 km
± 0.6 km
Number of Phase Applied1

Minimum Distance2
5.5 km (0.05°)

Travel Time Residual3
0.2 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)
