The earthquake activity of numerous volcanoes is closely monitored to provide warning signs of an imminent eruption. Large VOLCANIC eruptions, especially the explosive type, can release huge amounts of energy that can be recorded by seismographs even far from the source.

Recent volcanic activity in Canada has been experienced in BC and the Yukon. Worldwide, the majority of volcanoes and earthquakes are located in the same areas. This relationship is explained through a geological MODEL called plate tectonics.

In Eastern and Northern Canada, earthquakes are not RELATED to volcanic processes. Although volcanic rocks exist in many regions (sometimes as old as 2 billion years of age) and magmatic bodies can be found (the Monteregian Hills of Quebec are 60 million year old intrusive), these magmatic EVENTS are just too old to have any relationship with current earthquake occurrences. No volcanic or magmatic activity is currently underway in these parts of Canada.
