Magnitude 4.6 Earthquake of Hofn, Iceland 2014-09-14

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

a)  121km (75mi) WNW of Hofn, Iceland

b)  125km (78mi) S of Akureyri, Iceland

c)  212km (132mi) ENE of Reykjavik, Iceland

213km (132mi) ENE of Kopavogur, Iceland

e)  216km (134mi) ENE of Hafnarfjordur, Iceland

Location Uncertainty: 
  1. 4.6 mb
± 0.04
64.577°N, 17.619°W
5.0 km
± 1.9 km
Number of Phase Applied1

Minimum Distance2
178.6 km (1.60°)

Travel Time Residual3
1.11 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)
