36.8km (22.8mi)

Region : San Luis, Philippines

Magnitude 4.7 Earthquake of San Luis, Philippines 2014-10-25

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

a)  6km (4mi) WSW of San Luis, Philippines

b)  10km (6mi) W of Talacogon, Philippines

c)  30km (19mi) SW of Bah-Bah, Philippines

30km (19mi) WSW of San Francisco, Philippines

e)  852km (529mi) SE of Manila, Philippines

Location Uncertainty: 
4.7 mb
± 0.08
8.449°N, 125.690°E
36.8 km
± 7.9 km
Number of Phase Applied1

Minimum Distance2
153.0 km (1.37°)

Travel Time Residual3
0.99 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)
