Earthquake data:

Location : Position of Epicenter 

6.051°N 126.094°E

Depth : Depth of starting Rupture 

149.8 km

Region : Pondaguitan, Philippines

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

a) 35km (22mi) SSW of Pondaguitan, Philippines

b) 52km (32mi) ENE of Caburan, Philippines

c) 66km (41mi) SE of Malita, Philippines

d) 88km (55mi) SE of Santa Maria, Philippines

e) 938km (583mi) W of Koror Town, Palau

Location Uncertainty: 

Parameter	Value	Uncertainty
Magnitude	4.6 mb	± 0.1
Location	6.051°N 126.094°E	± 11.8 km
Depth	149.8 km	± 12.1
Number of Phase Applied1	30
Minimum Distance2	600.57 km (5.39°)
Travel Time Residual3	0.50 sec
Azimuthal Gap4	121°

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)
