49.9km (31.0mi)

Region : Kahale, Indonesia

Magnitude 4.2 Earthquake of Kahale, Indonesia 2014-09-17

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

a)  71km (44mi) S of Kahale, Indonesia

b)  155km (96mi) WSW of Waingapu, Indonesia

c)  210km (130mi) S of Bima, Indonesia

224km (139mi) SSW of Labuhanbajo, Indonesia

e)  745km (463mi) WSW of Dili, East Timor

Location Uncertainty: 
4.2 mb
± 0.16
10.341°S, 119.029°E
49.9 km
± 10.6 km
Number of Phase Applied1

Minimum Distance2
399.6 km (3.59°)

Travel Time Residual3
0.80 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)
