Vancouver earthquake part of a seismic swarm

A lot of people have been worried and wondering why a series of earthquakes these past few days. This morning's headliner earthquake near Vancouver Island didn't come alone. Scientists have recorded four more seismic events since 5:37 a.m., when the 5.8-magnitude quake shook things up this morning - and not for the first time this week.

From the Times Colonist in Canada:

From Monday to Wednesday afternoon, there had already been 15 earthquakes and aftershocks recorded by the Geological Survey of Canada's Sidney base, one as high as five on the 10-point magnitude scale that measures the seismic energy released by an earthquake.

"It's nothing to be worried about," said Garry Rogers, an earthquake scientist with the geological survey said Wednesday. "It reminds us that we're in a very active offshore activity area. It's one of the most active in the world."

Do you think this will be one of the signals that the world will end? Will still be huge earthquake coming? It seems that the events were spontaneous.
