Magnitude 3.5 Earthquake of Medford, Oklahoma 2014-09-08

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

a)  14km (9mi) WNW of Medford, Oklahoma

b)  50km (31mi) N of Enid, Oklahoma

c)  73km (45mi) WNW of Ponca City, Oklahoma

79km (49mi) WSW of Arkansas City, Kansas

e)  157km (98mi) NNW of Oklahoma City, Oklahoma

Location Uncertainty: 
3.5 ml
36.854°N, 97.887°W--
6.2 km
± 7.0 km
Number of Phase Applied1

Minimum Distance2

Travel Time Residual3
0.96 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)
