Latitude and longitude standard error estimates were computed before the data month of October 2002 and full error ellipses after.
Error estimates (great-circle distance, bearing, longitude component of error, and latitude component of error) were calculated for each ARGOS position and are available as supplementary material.
Variance was estimated for both latitude and longitude because Argos error varies between latitudinal and longitudinal components [50].
To minimise the PAT duration, a simplified correction of longitude and inclination errors of the GEO satellite's osculating Keplerian parameters has been suggested.
Furthermore, the errors for the remaining location classes, as provided by ARGOS-CLS, are 68th percentile predictions (separately for latitude and longitude) rather than full error distributions making it difficult to incorporate into animal movement models.
All individuals that were encountered were sampled, and latitude, longitude, and elevation (with error estimates < 10 m) were recorded at the point of capture using a GPS (Additional file 1).
Although errors in longitude and latitude seem to be large for these events, it is possible to observe the large confidence limits for the historical earthquakes, also in the published papers such as Kanamori et al. (2010), Batlló et al. (2008, 2010) and Tobin and Sykes (1968).
The earthquakes shown are those with precise hypocenters, for which the standard errors of latitude, longitude, and focal depth are less than 0.1°, 0.1°, and 20 km, respectively.
Figure 2(b) shows the 31 relocated hypocenters of the mainshock and aftershocks for which the standard errors of latitude, longitude, and focal depth are <0.03°, <0.03°, and <5 km, respectively.
Furthermore, only earthquakes with more precise hypocenters are shown in the following figures, those for which the standard errors of latitude, longitude and focal depth are less than 0.1°, 0.1° and 10 km, respectively.
