Depth : Depth of starting Rupture 

55.0 km

Region : Kaikoura, New Zealand
Magnitude 6.1 Earthquake of Kaikoura, New Zealand 2015-04-24

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

a) 68km (42mi) NW of Kaikoura, New Zealand

b) 82km (51mi) S of Richmond, New Zealand

c) 89km (55mi) SSW of Nelson, New Zealand

d) 99km (62mi) SW of Blenheim, New Zealand

e) 171km (106mi) WSW of Wellington, New Zealand

Location Uncertainty: 
6.1 mww
± 0.1
42.063°S 172.999°E
± 4.6 km
55.0 km
± 1.8
Number of Phase Applied1

Minimum Distance2
34.29 km (0.31°)

Travel Time Residual3
0.97 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)
