tephra and volcanic bombs. Lying above a remote mountain ridge in the Boundary Ranges of the Coast Mountains, it is responsible for lava flow eruptions in 1904 and older that traveled south through river valleys where they crossed the border into the U.S. state of Alaska and dammed the Blue River, a short tributary of the Unuk River. In doing so it formed several small lakes. This eruption had a massive effect on fish, plant and animal inhabitants of the valley, but there is no record of its impact on people, most likely because people were not in the remote area. The entire length of the lava flows are at least and still contain the original lava features from when they were erupted, including pressure ridges and lava channels. However, sections of the lava flows have collapsed into underlying lava tubes to form cavities. Tephra and scoria from The Volcano covers adjacent mountain ridges and even through it is very young, it has been reduced by erosion from alpine glacial ice found in the heavily glaciated Coast Mountains. The estimated volume of lava and ash from The Volcano is . 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. Mitigation and vulnerability In Canada, even though volcanoes pose significant threats to local communities and any sizable eruption would affect Canada's economy, the work of understanding the frequency and eruption characteristics at volcanoes in Canada is a slow process. This is because most of Canada's dormant and potentially active volcanoes are located in isolated jagged regions, very few scientists study Canadian volcanoes and the provision of money in the Canadian government is limited. Because of these issues, scientists studying Canada's volcanoes have a basic understanding
