Wstęp to to, że Cascades Volcanic Arc

Stretching over 700 mils from Lassen Volcanic National Park in California tu Garibaldi Volcanic Belt in British Columbia, thee Cascades Volcanic Arc is a defing exacure of thee Pacific Northwest. This chain of active and dormant wulcan es has been built by thee relentles forces of plate tectonics over the patt 36 million years. The arc is home to more than 2,300 known contac vents, includincluding 18 major stratouclear.

Tectonic Foundations of thee Arc

Thee Cascadia Subduction Zone

Te pierwsze engine behind thee Cascades is cascadia subduction Zone. Here, thee Juan dee Fuca Plate, a remnant of thee ancient Farallon Plate, is sliding benefiath thee North American Plate. Thi process, known as subduction, exists at a rate of rounghly 2 to 4 centieters per year.

Magma Composition and Eruptivie Style

Te magma produced in this subduction setting is rich in silica and disolved gases, making it highly viscous and prone to explosive eruptions. Unlike the fluid basaltic lavas seen in hawai, thee andesitic and dacitic magmas of te Cascades trap gas bubbles, leading to infinise pressure buildup. When this pressure is releaseid, it can produce amoviphic explosions, towering columns of ash, and fastmog pyroclastic flows.

In contrast to St. Helens, Mount Adams is a massive, shield- like stratovolano.
