1. Lassen Peak, CA

Lassen Peak is one of the most active volcanoes in the US

Lassen Peak in California had a notable eruption in 1915. The eruption caused debris of ash to fall in a 20-mile radius. The entire area of Lassen Volcanic National Park has been marked as the place of active volcanic activity for over three million years.

Geologists have found proof of this through finding several fumaroles, bubbling mud pits and springs throughout the area. Even if Lassen Peak has not caught the eyes of the geologists with any recent eruptions, they predict a future eruption may occur.

2. Mount Hood, OR

Mt. Hood

In Oregon, Mount Hood has been reported to show some explosive activity in the past 1500 years and even now, it has a potential threat to exploding lava. This mountain of 11,000-plus feet can be climbed to the top over the entire year. Usually, the ascents are reported to occur from May to June.

If you want to witness the explosion, you can stay in the Historic Timberline Lodge for a while. Or, you can hike through the sprawling trail surrounding Mt Hood National Forest.

3. Mount Rainier, WA
