Why Isn't Mount Denali a Volcano?

The video explores why Alaska, despite having many active volcanoes, has a volcanic gap known as the Denali Volcanic Gap. It explains the process of subduction and how it typically leads to volcanic eruptions. The Yakutat terrain, a sea floor plateau, affects subduction by creating a flat slab subduction, which alters the conditions necessary for volcano formation. Two main hypotheses are discussed: the lack of water in the subducting plate and the thick crust blocking magma. Recent studies suggest magma is present but unable to reach the surface due to these geological conditions.

Discuss the impact of flat slab subduction on magma formation in the Denali Volcanic Gap.

What evidence suggests that magma is present beneath the Denali Volcanic Gap?

Why is it unlikely that Denali will erupt in the near future?
