Mount Hood
If Mount Hood erupted there would be several hazards that could endanger lots of humans and animals as well as destroying buildings and other man made stuff. Lahars are fast moving flows of mud, rocks and debris that occurs when water from glaciers are released due to volcanic eruption. Since Mount Hood is covered in glaciers, lahars would be very dangerous and probably cause lots of destruction. If an eruption happened at Crater Rock, the place where scientists predict the next eruption to occur on the mountain, it would cause lahars to move down the west side of the mountain into the Sandy River and Zigzag River valleys. The lahar would hit many towns including Government Camp, Zigzag and Wildwood. Hot ash flows are ash avalanches that are blasted out of the volcano at very high speeds and usually destroys most things in their way. Hot ash flows have the potential to reach to reach kilometers into river valleys, so the same cities that are in the hazard zone for lahars are in the hazard zone for hot ash flows too. Landslides are rocks that fall off the sides of the volcano and roll down the side of the mountain. These have the potential to hit ski lodges, houses, cabins and can also injure people at the base of the mountain. Landslides are most likely to occur where the eruption occurred but there is a chance an eruption could trigger a landslide on any side of the mountain. Ash falls occur when the rising ash from a volcano settle back to earth, covering the land in centimeters of ash. much of the ash will fall to the earth near the volcano but some will be carried hundreds of miles away and affect other communities. Much like the eruption of Mount St. Helens, if Mount Hood erupted much of the ash would be dispersed around the mountain with the wind pushing it over to different towns. Centimeters of ash everywhere in the air would make it very hard to breath and would basically shut down transportation. Planes that fly through rising ash have suffered damage and could crash.
