Explanation of earthquake parameters and publication criteria.


Depth
Distance below sea level in kilometers.
33 km is used as a default depth for earthquakes determined to be shallow, but whose depth is not satisfactorily determined by the data. Default depths of 5 or 10 km are usually used in mid-continental areas and on mid-ocean ridges since earthquakes in these areas are usually shallower than 33 km.
UTC
Coordinated Universal Time

In the United States, Canada or Mexico, to convert to your local time, find your time zone and subtract the number of hours listed. Standard Time Daylight Time
Newfoundland UTC - 3½ hours UTC - 2½ hours
Atlantic UTC - 4 hours UTC - 3 hours
Eastern UTC - 5 hours UTC - 4 hours
Central UTC - 6 hours UTC - 5 hours
Mountain UTC - 7 hours UTC - 6 hours
Pacific UTC - 8 hours UTC - 7 hours
Alaska UTC - 9 hours UTC - 8 hours
Hawaii UTC - 10 hours
Aleutian UTC - 10 hours UTC - 9 hours


COMMENTS
The regions shown in the comments column are usually automatically-generated names from the Flinn-Engdahl (F-E) seismic and geographical regionalization scheme. The boundaries of these regions are defined at one-degree intervals and therefore differ from irregular political boundaries. More->
