Depth : Depth of starting Rupture

28.6km (17.8mi)

Region : Biha, Indonesia

Magnitude 4.5 Earthquake of Biha, Indonesia 2014-09-07

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

a)  183km (114mi) S of Biha, Indonesia

b)  230km (143mi) WSW of Labuan, Indonesia

c)  231km (144mi) SW of Telukbetung, Indonesia

233km (145mi) SW of Bandarlampung, Indonesia

e)  343km (213mi) WSW of Jakarta, Indonesia

Location Uncertainty: 
4.5 mb
± 0.12
6.980°S, 103.835°E
28.6 km
± 3.7 km
Number of Phase Applied1

Minimum Distance2
305.6 km (2.75°)

Travel Time Residual3
0.98 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)
