Magnitude 4.2 Earthquake of Maketu, New Zealand 2014-10-26

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

a)  100km (62mi) NNE of Maketu, New Zealand

b)  107km (66mi) N of Whakatane, New Zealand

c)  109km (68mi) NE of Tauranga, New Zealand

145km (90mi) NNE of Rotorua, New Zealand

e)  515km (320mi) NNE of Wellington, New Zealand

Location Uncertainty: 
4.2 ml
36.990°S, 177.040°E
275.0 km
± 8.4 km
Number of Phase Applied1

Minimum Distance2

Travel Time Residual3
0.74 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)
