The Cascade Volcanic Belt was formed by the subduction of the Juan de Fuca Plate, which is a remnant of the much larger Farallon Plate, under the North American Plate. Most of the volcanoes in this belt are frequently active, and includes more than a dozen large volcanoes. They share general characteristics, but each has its own unique geological traits and history. Unlike in most subduction zones, there is no trench present along the continental margin. Instead, terranes and the accretionary wedge have been uplifted to form a series of coast ranges and exotic mountains. Lassen Peak, which last erupted in 1917, is the southernmost historically active volcano in the belt, and the northernmost, Mount Silverthrone, which is a circular 20km wide, deeply dissected caldera complex. Some of the major cities in the region are Portland, Seattle and Vancouver. The Juan de Fuca plate sinks below the North America plate at the Cascadia subduction zone. ...

The Cascade Volcanic Belt is about 37 million years old. However, the present day Cascade volcanoes are less than 100 thousand years old. It is important to realize that the growth of the Cascade Volcanic Belt is not the foundation of the Cascade Range. The Cascade Range is much younger, only 5-7 milion years old. 5-7 million years ago, the northern end of the Juan de Fuca Plate, which is now the Explorer Plate, broke off, forming what is now the Nootka Fault.

While the Cascade Volcanic Belt (a geological term) includes volcanoes such as Mount Meager and Mount Garibaldi, which lie north of the Fraser River, the Cascade Range (a geographic term) is considered to have its northern boundary at the Fraser. However this terminology is not universally adhered to; in particular the phrase "the volcanoes of the High Cascades" is sometimes understood to include the peaks north of the Fraser, and sometimes not.^{[citation needed]} This article includes a list of works cited but its sources remain unclear because it lacks in-text citations. ...

Eruptions of the Cascades

The Cascade volcanoes in the belt have constructed more than 100 eruptions, most of them have been explosive eruptions in the past few thousand years. However, certain Cascade volcanoes can be dormant for hundreds or thousands of years between eruptions, sush as Mount Meager which hasn't erupted for about 2,350 years, threw ash as far as southern Alberta.

Historical eruptions

Historical eruptions have occurred in Washington, Oregon and in Northern California. In contrast, volcanoes in southern British Columbia, central and southern Oregon are currently dormant. The regions lacking new eruptions keep in touch to positions of fracture zones that offset the Gorda Ridge, Explorer Ridge and the Juan de Fuca Ridge.

Recent eruptions

Renewed volcanic activity in the Cascade Volcanic Belt, such as the 1980 eruption of Mount St. Helens, has offered a great deal of evidence about the structure of the Cascades. One effect of the 1980 eruption was a greater knowledge of the influence of landslides and volcanic development in the evolution of volcanic terrain. A vast piece on the north side of Mount St. Helens dropped and formed a jumbled landslide environment several kilometers away from the volcano. Pyroclastic flows and lahars moved across the countryside. Parallel episodes have also happened at Mount Shasta and other Cascade volcanoes in prehistoric times. The 1980 eruption of Mount St. ...

An earthquake at 8:32 a.m. on May 18, 1980, caused the entire weakened north face to slide away. An ash column rose high into the atmosphere and deposited ash in 11 U.S. states.

2350 BC eruption of Mount Meager

Main article: Mount Meager

The 2350 BC eruption of Mount Meager is the most recent, major catastrophic eruptions in British Columbia and in Canada. The eruption came from a vent on the north-east side of Plinth Peak. It was a Plinian style eruption with a VEI=6. The eruption was episodic, and the formation comprises airfall pumice, pyroclastic flows, welded breccias, lahars and a small glassy, porphyritic dacite lava flow. The eruption was so great that thin, very finegrained, distal deposits of tephra have been identified in Alberta and sent an ash column at least 20 km high into the stratosphere.

7700 BC eruption of Mount Mazama

Main article: Mount Mazama

The 7700 BC eruption of Mount Mazama was a large catastrophic eruption in U.S. state of Oregon. It is estimated to have been 42 times larger than the 1980 eruption of Mount St. Helens. It began with a large eruption column with pumice and ash that erupted from a single vent. The eruption was so great that most of Mount Mazama collapsed to form a caldera and subsequent smaller eruptions occurred as water began to fill in the caldera to form Crater Lake. Volcanic ash from the eruption was carried across most of the Pacific Northwest as well as parts of southern Canada.
