Region : Shikotan, Russia

Magnituae 4.8 Earthquake of Shikotan, Russia 2014-09-18

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

a) 33km (21mi) W of Shikotan, Russia

b) 83km (52mi) NE of Nemuro, Japan

c) 97km (60mi) ENE of Shibetsu, Japan

d) 164km (102mi) E of Abashiri, Japan

e) 1068km (664mi) NNE of Tokyo, Japan

Location Uncertainty: 
4.8 mb
± 0.03
43.854°N, 146.311°E
77.5 km
± 5.7 km
Number of Phase Applied1

Minimum Distance2
300.1 km (2.70°)

Travel Time Residual3
0.89 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)
