Seasonal steam rising from Mount Baker is a reminder to residents that the picturesque mountain across the border is among the Cascade volcanoes.

The mountain range features a series of once-active volcanoes, but the smoking look isn乌鸦传媒檛 cause for concern.

乌鸦传媒淚t乌鸦传媒檚 mostly hot water,乌鸦传媒� explained Dante Canil a professor in the School of Earth and Ocean Sciences at the University of Victoria.

Baker is what would be called a dormant volcano, as it hasn乌鸦传媒檛 erupted in a major way for about 10,000 years. It does have a magmatic system, as do others in the Cascades considered more active, such as Mount Rainier and Mount St. Helens.

Baker has vents 乌鸦传媒� or fumaroles 乌鸦传媒� that go down into the mountain.

Steam is usually a result of snow melt and other water getting into the magmatic system, which heats it well beyond its boiling point.

乌鸦传媒淎 lot like a hot spring,乌鸦传媒� Canil said. 乌鸦传媒淚t also depends on the air above it whether you see the steam.乌鸦传媒�

The nature of the conditions make it a bit seasonal, with the steam spotted and making headlines, most frequently in the spring.

Mount Baker has been quiet, but it could still erupt someday. The impact in Greater Victoria would be minimal.

乌鸦传媒淥f all the nearby volcanoes, it would be the least concerning,乌鸦传媒� Canil said, noting Mount St. Helens, dubbed a frequent erupter, would be a far more likely culprit.

With prevailing west to east winds, experts guess even ash fall would be minimal as the Cascades spread ash deposits mostly to the east.

乌鸦传媒淓ven if Baker were to erupt 乌鸦传媒� in a typical eruption we乌鸦传媒檇 get maybe less than 1 millimetre,乌鸦传媒� Canil said.

There are other hazards to those volcanoes for people living close to them. When the snow cap melts during an eruption, it sends a flood of ash and mud, with the consistency of concrete, down the mountain at alarming speeds.

乌鸦传媒淔or people nearby a volcano, that乌鸦传媒檚 as much risk as an eruption of magma,乌鸦传媒� Canil said.
