Earthquake data:

Location : Position of Epicenter 

24.003°N 122.927°E

Depth : Depth of starting Rupture 

23.8km (14.8mi)

Region : Yonakuni, Japan

Magnitude 4.8 Earthquake of Yonakuni, Japan 2014-09-06

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

a) 51km (32mi) S of Yonakuni, Japan

b) 127km (79mi) ESE of Su'ao, Taiwan

c) 130km (81mi) WSW of Ishigaki, Japan

d) 134km (83mi) E of Hualian, Taiwan

e) 917km (570mi) ENE of Hong Kong, Hong Kong

Location Uncertainty: 
4.8 mb
± 0.05
24.003°N, 122.927°E
23.8 km
± 5.0 km
Number of Phase Applied1

Minimum Distance2
136.8 km (1.23°)

Travel Time Residual3
0.86 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)
