Magnitude 2.5 Earthquake of Trinidad, Colorado 2014-10-20

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

a)  27km (17mi) W of Trinidad, Colorado

b)  118km (73mi) S of Pueblo, Colorado

c)  127km (79mi) S of Pueblo West, Colorado

142km (88mi) SSE of Canon City, Colorado

Location Uncertainty: 
2.5 ml
± 0.09
37.202°N, 104.809°W
5.0 km
± 2.0 km
Number of Phase Applied1

Minimum Distance2
36.1 km (0.32°)

Travel Time Residual3
1.45 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)
