Earthquake data:

Location : Position of Epicenter 

  1. 37.682°N 121.730°W

Depth : Depth of starting Rupture 

3.1km (1.9mi)

Region :Livermore, California

Magnitude 2.6 Earthquake of Livermore, California 2014-09-19

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

a)  3km (2mi) E of Livermore, California

b)  12km (7mi) E of Pleasanton, California

c)  18km (11mi) E of Dublin, California

24km (15mi) ESE of San Ramon, California

Location Uncertainty: 
2.6 md
± 0.12
37.682°N, 121.730°W
± 0.3 km
3.1 km
± 0.5 km
Number of Phase Applied1

Minimum Distance2
7.1 km (0.06°)

Travel Time Residual3
0.14 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)
