Magnitude 3.5 Earthquake of Covelo, California 2014-09-14

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

a)  10km (6mi) ESE of Covelo, California

b)  67km (42mi) N of Ukiah, California

c)  89km (55mi) WSW of Red Bluff, California

98km (61mi) NNW of Clearlake, California

Location Uncertainty: 
3.5 Ml
± 0.20
39.757°N, 123.134°W
± 0.3 km
6.5 km
± 0.5 km
Number of Phase Applied1

Minimum Distance2
16.0 km (0.14°)

Travel Time Residual3
0.27 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)
