From October 9, 2007 to May 15, 2008, a series of earthquakes measuring up to 2.9 magnitude occurred in the Nechako Basin some west of Nazko Cone. Most of these tremors occurred below the surface, indicating they originated within the lowermost crust. Analysis of seismic waves suggest that the earthquake swarm was caused by brittle failure and fracturing of rock at depth from magma intrusion. No volcanic eruption was likely as the number and size of the seismic events were too small. Nevertheless, this suggests that the Anahim hotspot is seismically active and that small magma movements are still possible. Although these earthquakes were too small to be felt, they generated substantial local interest as they represented a significant concentration of seismic activity within the Anahim Volcanic Belt.
