Grab your hard hat and climbing gear, too, because we’re also going to rappel down the waterfall contact between basalt and granite somewhere around Mount Garibaldi.

In Canada, there is no ongoing monitoring at individual volcanoes because eruptions are so infrequent. However, Natural Resources Canada’s Canadian National Seismograph Network (CNSN) currently monitors volcanic regions in British Columbia and the Yukon and can detect very small earthquakes. If unrest were detected near a Canadian volcano, NRCan would respond by providing additional targeted monitoring of seismic activity, ground deformation, gas emissions, and other phenomena in order to find out what was happening, and would prepare hazard maps and work closely with emergency planning agencies to ensure that accurate hazard information was available…
