Magnitude 2.9 Earthquake of Stella, Puerto Rico 2014-09-11

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

a)  46km (29mi) WSW of Stella, Puerto Rico

b)   52km (32mi) W of Cabo Rojo, Puerto Rico

c)  53km (33mi) W of Mayaguez, Puerto Rico

d)  53km (33mi) W of Hormigueros, Puerto Rico

  1. e)  166km (103mi) WSW of San Juan, Puerto Rico

Location Uncertainty: 
2.9 Md
± 0.00
18.129°N, 67.636°W
± 1.5 km
69.0 km
± 1.3 km
Number of Phase Applied1

Minimum Distance2
57.4 km (0.52°)

Travel Time Residual3
0.25 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)
