Plinian Eruptions - U.S. National Park Service
Plinian eruptions are extremely explosive eruptions, producing ash columns that extend many tens of miles into the stratosphere and that spread out into an umbrella shape. These large eruptions produce widespread deposits of fallout ash.

1997年11月4日 · Plinian eruptions are associated with volatile-rich dacitic to rhyolitic lava, and they typically erupt from stratovolcanoes. A Plinian eruption can continue for hours or days, sustaining a giant eruptive column. The thrust/force of the expanding gases results in the volcanic material being ejected at speeds of several hundred meters per second.

2024年2月7日 · Plinian eruptions are highly explosive eruptions resembling the 79 AD Mt. Vesuvius eruption. They mostly form from volatile-rich, highly viscous magma high in silica. However, they can also involve intermediate to basaltic magmas.
How Volcanoes Work - Plinian eruptions
Plinian eruptions generate large eruptive columns that are powered upward partly by the thrust of expanding gases, and by convective forces with exit velocities of several hundred meters per second. Some reach heights of ~45 km.
