KITIMAT B.C. -- Did you feel the ground shake yesterday?

No one else did either -- despite an alert sent out by the U.S. Geological Survey that a magnitude 6.5 earthquake struck off southeast of Kitimat Labour Day afternoon.

Alison Bird of Natural Resources Canada says a computer glitch led to the erroneous report.

She says there was no earthquake in the Kitimat area yesterday afternoon.

Bird says the automated system isn't perfect at processing data.

She says it's possible that two small quakes at different locations were detected as one event.
