Earthquake data:

Location : Position of Epicenter 

19.698°S 177.794°W

Depth : Depth of starting Rupture 

434.4km (269.9mi)

Region : Ndoi Island, Fiji

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

a) 141km (88mi) NE of Ndoi Island, Fiji

b) 313km (194mi) WNW of Nuku`alofa, Tonga

c) 432km (268mi) ESE of Suva, Fiji

d) 470km (292mi) SE of Lambasa, Fiji

e) 546km (339mi) ESE of Nadi, Fiji

Location Uncertainty: 

Parameter	Value	Uncertainty
Magnitude	7.1 mwc	± 0.03
Location	19.698°S, 177.794°W	--
Depth	434.4 km	± 3.8 km
Number of Phase Applied1	239
Minimum Distance2	829.3 km (7.45°)
Travel Time Residual3	0.73 sec
Azimuthal Gap4	21°

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)
