New research reveals that long-dormant volcanoes in the Cascades region of the Pacific Northwest still have substantial magma reservoirs beneath them.
About Cascade Range:
It is a prominent collection of mountains found in the Pacific Northwest area of the northwestern United States and southwestern Canada.
The range was formed by the subduction of the Juan de Fuca Plate beneath the North American Plate, which continues to drive volcanic activity.
It is known for its snow-capped peaks,massive glaciers, steep scree slopes, and lush forests.
The range is home to 4375 named mountains, the highest and most visible of which is Mount Rainier 4,392 m.
It includes both volcanic and non-volcanic mountains, including the rugged spires of the North Cascades, and the notable volcanoes known as the High Cascades.
The Cascades are part of the Pacific Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean.
All of the known historic eruptions in the contiguous United States have been from Cascade volcanoes.
