    19.698°S 177.794°W

    Depth : Depth of starting Rupture 

    434.4km (269.9mi)

    Region : Ndoi Island, Fiji

    Magnitude 7.1 Earthquake of Ndoi Island, Fiji 2014-11-01

    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: 
    7.1 mwc
    ± 0.03
    19.698°S, 177.794°W
    434.4 km
    ± 3.8 km
    Number of Phase Applied1

    Minimum Distance2
    829.3 km (7.45°)

    Travel Time Residual3
    0.73 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)
