Earthquake data:

Location : Position of Epicenter 

5.077°N 120.796°E

Depth : Depth of starting Rupture 

6.0km (3.7mi)

Region : Manubul, Philippines

Magnitude 5.1 Earthquake of Manubul, Philippines 2014-09-09

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

a)  43km (27mi) S of Manubul, Philippines

b)  51km (32mi) S of Siasi, Philippines

c)  108km (67mi) SSW of Anuling, Philippines

110km (68mi) SSW of Jolo, Philippines

Location Uncertainty: 
5.1 mb
± 0.05
5.077°N, 120.796°E
6.0 km
± 3.3 km
Number of Phase Applied1

Minimum Distance2
255.0 km (2.29°)

Travel Time Residual3
0.88 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)
