Plinian eruptions or Vesuvian eruptions are volcanic eruptions marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii. The eruption was described in a letter [1] written by Pliny the Younger, after the death of his uncle Pliny the Elder.
Zabriskie Point is a part of the Amargosa Range located east of Death Valley in Death Valley National Park in California, United States, noted for its erosional landscape. It is composed of sediments from Furnace Creek Lake, which dried up 5 million years ago—long before Death Valley came into existence.
The 1980 eruption of Mount St. Helens in Washington, which ripped apart the volcano's summit, was a Plinian eruption of Volcanic Explosivity Index (VEI) 5. [3] The strongest types of eruptions, with a VEI of 8, are so-called "Ultra-Plinian" eruptions, such as the one at Lake Toba 74 thousand years ago, which put out 2800 times the material ...
A.D. 79: Mount Vesuvius, Italy. Mount Vesuvius has erupted eight times in the last 17,000 years, most recently in 1944, but the big one was in A.D. 17. One of the most violent eruptions in history ...

The Ubehebe Craters are a volcanic field in the northern Death Valley of California, consisting of 14–16 craters in a 3-square-kilometre (1.2 sq mi) area. The largest of the craters is the 800 metres (2,600 ft) wide and 235 metres (771 ft) deep Ubehebe Crater.
The Long Valley Caldera was formed by a super-eruption about 760,000 years ago that blasted 140 cubic miles of magma, covering much of east-central California in hot ash that was blown as far away ...
The 1912 eruption was the largest eruption by volume in the 20th century, erupting a magma volume of about 13 cubic kilometers (3.1 cu mi). As many as 14 major earthquakes between M s {\displaystyle M_{\text{s}}} 6 to 7 , and over 100 earthquakes greater than M s {\displaystyle M_{\text{s}}} 5, resulted from the collapse of the caldera at Mount ...
