A series of earthquakes of less than magnitude 3.0 were recorded by seismographs in the Baezaeko River region west of Nazko Cone in the Anahim Volcanic Belt on October 9 , 2007 . The cause of these earthquakes was magma intruding into rock below the surface . Since then more than 1,000 small earthquakes have been recorded . Because of the small size of the earthquake swarms , Natural Resources Canada has added more seismographs in the region for better location and depth accuracy . However , the size and number of the 2007 earthquake swarms indicate there is currently no threat of an eruption . Before magma could erupt in the area adjacent to Nazko Cone , it is expected the size and number of the earthquakes would rise considerably , presaging an eruption
