Region : Miyako, Japan
Directions and Distances :Directions and Distances from Geographical Reference in Close Proximity Which can be effected by Location Uncertainty
a) 132km (82mi) ENE of Miyako, Japan
b) 137km (85mi) ENE of Yamada, Japan
c) 145km (90mi) ENE of Otsuchi, Japan
d) 151km (94mi) ENE of Kamaishi, Japan
e) 572km (355mi) NE of Tokyo, Japan
± 5.5 km
Number of Phase Applied1
237.4 km (2.13°)
Travel Time Residual3
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.
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.
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)
