5.0km (3.1mi)

Region : Arlington, Texas

Magnitude 2.5 Earthquake of Arlington, Texas 2014-09-13

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

a)  1km (1mi) S of Arlington, Texas

b)  10km (6mi) WSW of Grand Prairie, Texas

c)  13km (8mi) S of Euless, Texas

13km (8mi) SSE of Hurst, Texas

Location Uncertainty: 
  1. 2.5 mb_lg
± 0.18
32.718°N, 97.108°W
5.0 km
± 2.0 km
Number of Phase Applied1

Minimum Distance2
50.5 km (0.45°)

Travel Time Residual3
1.20 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)
