If you compare the maps that illustrate earthquake zones andvolcanic zones, you will find them matching to each other. The main theorybehind both these natural calamities lie in the plate tectonics.
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. You can find additional explanations on plate tectonics: • USGS • University of Nevada • U.C. Berkeley In Eastern and Northern Canada, earthquakes are not related to volcanic processes. Although volcanic rocks exist in many regions (sometimes as old as 2 billions years of age) and magmatic bodies can be found (the Monteregian Hills of Quebec are 60 million year old intrusives), these magmatic events are just too old to have any relationship with current earthquake occurrences.
