last updated: 03/06/09 08:04.31 (PST)
On Friday March 6 2009 at 2:50 AM (PST) the USArray seismic network recorded an earthquake (preliminary Mw 6.4) located north of Svalbard.
Initial source parameters for this tremor are indicated below. The epicentral distance (i.e. distance separating the epicenter and the closest station in the recording network, A24A) for the USArray is 4901 km (44.15 degrees).
If you felt the quake, the USGS would like to know. Please add your comments to the USGS page "Did you feel it?".

Why does the map look disproportionate?
The earth is a spheroid, hence trying to represent a 3-D spherical
object on a 2-D plane requires some remapping. The Mercator
projection used in the map is conformal and gets distorted at the poles (above
70°N and below -70°S) since linear scale becomes infinitely
high at the poles. For more information on this
projection and its limitations, visit the Wikipedia
page.
