Ash from this eruption has been found in the peat bogs of Ireland. Photo by J. On cold clear days that follow damp weather, condensation of water vapor causes a vigorous steam plume.

Yet since the most recent ice age , this volcano has produced some of the largest and most explosive eruptions in the United States. Since the most recent ice age, it has erupted multiple times during at least six separate episodes. Glacier Peak and Mount St. Helens are the only volcanos in Washington State that have generated very large explosive eruptions in the past 15, years.
During some of these eruptions, Glacier Peak erupted massive volumes of volcanic ash that was carried eastward by winds. Lahars volcanic mudflows rushed down the same river valleys that now sustain farmlands and communities. Emergency Management Global Menu Close panel. Help FAQ. During an eruption at Mount Baker, you can expect: Lahars volcanic mudflows caused by melting of snow and ice that flow for tens of miles down valleys. Helens, Washington in A lahar is a special type of debris flow or mudflow produced when volcanic materials interact with ice, snow, or surface water.
During eruptions, snow and ice melted by hot volcanic debris can form large lahars, but lahars can also occur between eruptions when loose volcanic materials are eroded and carried away by water. Lahars are common at many stratovolcanoes, especially those with extensive snow and ice cover like Mount Baker. They may travel great distances via river drainages and can be extremely destructive. The volume of ice on Mount Baker about 1.
In an eruption, all of this snow and ice could melt and produce lahars. In the past century, many floods caused by weather have crossed the drainage divide this way. However, lahars of this size occur only once every 14, years, and a weather flood is far more likely than a volcano-related flood. Precautionary methods for dealing with lahars are similar to those for dealing with floods. If a large lahar or flood did occur, pre-eruptive warning signs would give emergency personnel time to warn people in low-lying areas of the hazard.
Reduced visibility due to remobilized volcanic ash during a eruption of Redoubt volcano, Alaska. Explosive eruptions of Mount Baker that generate volcanic ash have been less frequent than at other Cascade volcanoes, but they still pose a potential hazard. A large explosive eruption is unlikely. Meteorological data indicate ash fallout from Mount Baker would most likely occur due east of the volcano, so the chance of any ash falling directly on Vancouver is extremely low.
There is a much higher chance of ash falling in the eastern Fraser Valley. Fortunately, only a narrow area would likely be affected at any given time, and the overall probability of ash fall anywhere in British Columbia is still very low. During an explosive eruption of Mount Baker, any ash that fell to the ground would damage machines, especially those requiring air filters, like cars, computers, and air conditioners.
Some power distribution equipment might fail, resulting in power outages, and the ash might affect telephone service. Reduced visibility and accumulations of slippery ash on roads would make driving difficult and potentially more dangerous. Medical services might see an increase in the number of patients with respiratory and eye symptoms.
Dust masks would be necessary where ash concentrations were high. Ash cleanup would be time-consuming.
