Earthquake swarm in British Columbia

While Mount St Helens has gone quiet these last few months, with no visible activity from the crater at night for almost six months, there is growing interest in an earthquake swarm occurring further north in British Columbia, near Quesnel. According to Natural Resources Canada, Starting on October 10 an interesting series of earthquakes has been occurring in the upper Baezaeko River region, about 100km west of Quesnel, BC. More than 100 microearthquakes have occurred in this earthquake swarm as of 8 a.m. PDT October 15. These earthquakes are deep in the Earth's crust and none have been reported felt. This region is a known volcanic zone. The earthquakes are located about 20 km to the west of Nazko Cone which last erupted about 7000 years ago.
