Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera. The National Park Service said the eruption covered an area ...

The two "mega-disasters" of the 2004 Indian Ocean tsunami and Hurricane Katrina in 2005 inspired the series and provided a reference point for many of the episodes. [1] Excepting only two shows devoted to man-made disasters , the threats explored can be divided into three general categories: meteorological , geological , and cosmic hazards.
The removal of the north side of the mountain (13% of the cone's volume) reduced Mount St. Helens's height by about 1,300 ft (400 m) and left a crater 1 to 2 mi (1.6 to 3.2 km) wide and 2,100 ft (640 m) deep with its north end open in a huge breach.
1912: Novarupta Volcano, Alaska. No other historical eruption in North America can compare to the one that created the Novarupta Volcano in 1912. The biggest eruption on Earth in the 20th century ...
Rated a 6 on the volcanic explosivity index, [6] the 60-hour-long eruption expelled 3.1 to 3.6 cubic miles (13 to 15 km 3) of ash, thirty times as much as the 1980 eruption of Mount St. Helens. [7] [8] [9] The erupted magma of rhyolite, dacite, and andesite [10] resulted in more than 4.1 cubic miles (17 km 3) of air fall tuff and approximately ...
The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
[1] [2] Volcanic eruptions can generally be characterized as either explosive eruptions, sudden ejections of rock and ash, or effusive eruptions, relatively gentle outpourings of lava. [3] A separate list is given below for each type. There have probably been many such eruptions during Earth's history beyond those shown in these lists.
