Date/Time (UTC) The time in UTC the earthquake occurred
Distances to cities Distances from epicenter to local cities + population and local time in these cities when the earthquake occurred
Latitude Epicenter latitude in degrees
Longitude Epicenter longitude in degrees
Depth Hypocentral depth
Magnitude Magnitude type and value



Region Flinn-Engdahl region
rms Root-mean-square travel time residual, in seconds
Nb stations Number of seismic stations which reported arrival times for this earthquake.
Nb Phases Number of arrival-time observations used to compute the hypocenter location.
Gap The largest azimuthal gap between azimuthally adjacent stations (in degrees).
95% confidence Ellipse 95% confidence ellipse on the epicentral coordinate
Semi-major axis Length of the semi-major axis of the 95% confidence ellipse
Semi-minor axis Length of the semi-minor axis of the 95% confidence ellipse
Azimuth Azimuth of the semi-major axis of the 95% confidence ellipse

Slow Observed slowness (seconds/degree)
T if T, this phase has been used in the location. If empty, this phase has not been used in the location.
A if A, this azimuth has been used in the location. If empty, this azimuth has not been used in the location.
S if S, this slowness has been used in the location. If empty, this slowness has not been used in the location.
