Mount Hood, Oregon
Mount Hood is the highest peak in the state and located around 90 minutes from Portland, the state’s biggest city. The volcano has been active intermittently over the past half a million years, with the last major eruption taking place around 300 years ago. The next eruption might not be powerful, but it could still cause serious problems in the surrounding area. Pyroclastic flows, ash clouds, and mudflows caused by collapsing domes could spell disaster.
