Magnitude 2.7 Earthquake of Cherokee, Oklahoma 2014-09-17

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

a)  23km (14mi) E of Cherokee, Oklahoma

b)  44km (27mi) NNW of Enid, Oklahoma

c)  89km (55mi) W of Ponca City, Oklahoma

99km (62mi) WSW of Arkansas City, Kansas

e)  151km (94mi) NNW of Oklahoma City, Oklahoma

Location Uncertainty: 
2.7 ml
36.755°N, 98.091°W--
4.7 km
± 7.1 km
Number of Phase Applied1

Minimum Distance2

Travel Time Residual3
0.91 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)
