 The Anahim hotspot is the only notable earthquake zone in the Canadian Cordillera away from the British Columbia Coast . A series of < 3 @.@ 0 magnitude earthquakes began October 9 , 2007 with its epicenter in the McNaughton Lake region near Nazko Cone , which could signal the resumption of intense subterranean volcanic activity in the area . Thirty @-@ four such < 3 @.@ 0 magnitude earthquakes were observed on October 10 , 2007 alone . Since then more than 1 @,@ 000 small earthquakes have been recorded . They are thought to have originated 25 km ( 16 mi ) below the surface , but none of them have been felt by people . The cause of this seismic activity is believed to be the upwelling of 500 @,@ 000 m3 ( 650 @,@ 000 cu yd ) of magma , because the area is not close to any faults or tectonic plate boundaries . This is the first indication of potential volcanic activity in Canada since around 1830 to 1850 in northwestern British Columbia .
