Earthquake data:

Location : Position of Epicenter 

40.121°N 141.869°E

Depth : Depth of starting Rupture 

75.4km (46.9mi)

Region : Ichinohe, Japan

Magnitude 4.6 Earthquake of Ichinohe, Japan 2014-09-10

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

a) 49km (30mi) E of Ichinohe, Japan

b) 52km (32mi) SE of Hachinohe, Japan

c) 54km (34mi) N of Miyako, Japan

d) 73km (45mi) N of Yamada, Japan

e) 527km (327mi) NNE of Tokyo, Japan

Location Uncertainty: 
5.1 mb
± 0.04
40.122°N, 141.869°E
75.4 km
± 7.1 km
Number of Phase Applied1

Minimum Distance2
236.8 km (2.13°)

Travel Time Residual3
1.01 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)
