Mount Hood is considered the Oregon volcano most likely to erupt. [8] The odds of an eruption in the next 30 years are estimated at between 3 and 7%, so the U.S. Geological Survey (USGS) characterizes it as "potentially active", but the mountain is informally considered dormant. [9]
Newberry Volcano's location in Oregon relative to other major volcanoes. The center of Newberry Volcano lies 20 miles (32 km) to the south of the city of Bend, [3] at the intersection of Deschutes, Klamath and Lake counties in Oregon, [4] where it is one of the most accessible volcanoes in the state.

This is a list of Cascade volcanoes, i.e. volcanoes formed as a result of subduction along the Cascadia subduction zone in the Pacific Northwest of North America. The volcanoes are listed from north to south, by province or state: British Columbia , Washington , Oregon , and California .
Olallie Butte is located within Jefferson, Marion, and Wasco counties, all within the northwestern to north-central part [4] of the U.S. state of Oregon. [2] [5] The volcano lies just outside [6] the irregularly shaped Olallie Roadless Area, which lies within the Mount Hood National Forest to the west of the major crest of the Cascade Range and directly north of the Mount Jefferson Wilderness.

The Sand Mountain Field is part of the Cascade volcanic arc and is located at the western edge of the High Cascades segment [1] of the central Oregon Cascades, [2] near the upper McKenzie River watershed [1] in Oregon, in the United States. [3] It encompasses an area of 29 square miles (76 km 2) [4] and has a maximum elevation of 5,463 feet ...
Axial Seamount is the youngest volcano and current eruptive center of the Cobb–Eickelberg Seamount chain, a chain of seamounts that terminates south of Alaska. [6] Axial lies where the chain intersects with the Juan de Fuca Ridge, [7] approximately 480 km (298 mi) west of Oregon.
Pelican Butte is the most prominent shield volcano in the southern Oregon Cascades and has a large volume at 4.8 cubic miles (20 km 3), making it one of the bigger Quaternary volcanoes in the region, approaching the size of some of the range's stratovolcanoes. While still part of the Cascades, Pelican Butte is disconnected from the main axis ...
