  1. Earthquake data:

Location : Position of Epicenter 

26.233°N 127.375°E

Depth : Depth of starting Rupture 

53.3km (33.1mi)

Region : Naha-shi, Japan

Magnitude 5.4 Earthquake of Naha-shi, Japan 2014-10-14

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

a)  30km (19mi) W of Naha-shi, Japan

b)    30km (19mi) W of Tomigusuku, Japan

c)  31km (19mi) WNW of Itoman, Japan

d)  38km (24mi) W of Ginowan, Japan

e)  1257km (781mi) S of Seoul, South Korea

Location Uncertainty: 
5.4 mb
± 0.04
26.233°N, 127.375°E
53.3 km
± 6.4 km
Number of Phase Applied1

Minimum Distance2
388.2 km (3.49°)

Travel Time Residual3
1.33 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)
