last updated: 01/08/08 16:40.19 (PST)
On Saturday January 5 2008 through Sunday January 6th the USArray seismic network recorded an earthquake swarm located in the Queen Charlotte Islands Region of the west coast of Canada.
Initial source parameters for these tremors are indicated below. The epicentral distance (i.e. distance separating the epicenter of the first earthquake and the closest station in the recording network, C03A) for the USArray is 561 km (5.05 degrees).
If you felt the quake, the USGS would like to know. Please add your comments to the USGS page "Did you feel it?".
Location Maps
The red stars denote the earthquake epicenters. Triangle symbols are active stations at the time of the earthquake in the USArray (excluding ANSS backbone stations, which are represented by a diamond symbol) and colored by network. Gray lines are major rivers, lakes are dark blue.
