Is Mt Rainier an explosive or a quiet eruption?

Answer 1

Mount Rainier is considered a potentially dangerous stratovolcano that has the potential for explosive eruptions due to its composition of thick andesitic lava. However, historically, Mount Rainier has mostly experienced effusive eruptions, which are characterized by slower-moving lava flows rather than explosive eruptions. Nonetheless, the volcano's history shows evidence of both types of eruptions, with the potential for future explosive activity due to the buildup of pressure within the volcano.

Answer 2

Oh, dude, Mt. Rainier is known for having explosive eruptions, like a volcano with a fiery temper tantrum. It's not the quiet type that just whispers a little lava here and there. So, yeah, if you're hanging out near Mt. Rainier when it decides to blow, you better run faster than you would from a bee at a picnic.

Answer 3

Well, honey, let me break it down for you. Mount Rainier is known for having explosive eruptions due to its steep-sided volcanic cone and the potential for building up pressure from the magma beneath. So, yeah, it's not exactly the quiet type when it decides to blow its top. Just keep your distance and enjoy the show from afar!

Answer 4

Mount Rainier is one of many volcanoes in the Cascade Mountain Range. It is one of the tallest mountains in North America, and it did not gain this topographic stature by frequently blowing its top as Mount St. Helens did in 1980 or Mount Mazama did around 5677 B.C. creating Crater Lake; its tall stature would seem to indicate most of its eruptions have been "mountain-building" -- creating new rock from lava flows.

However, Mount St. Helens and Mount Mazama are also both part of the same Cascade volcanic mountain range as Mount Rainier, so a mountain-destroying eruption similar to the St. Helens or even Mazama blasts (the latter, obvious by means of its more complete self-destruction, much stronger) is definitely possible.

Even a mountain-building eruption, however, is likely to be rife with explosive phases, especially toward the beginning as it would 'clear the pipes.' Mount Rainier erupted as many as 6 times in the 1800s, but -- aside from tremors -- was quiet throughout the 20th century and, thus far, the 21st century. European explorers and settlers documented very noticeable volcanic plumes from Rainier during the 1800s.

Relative to Mount St. Helens, Rainier is an older and taller mountain (and has more glacial volume and mass than St. Helens did even prior to its 1980 eruption), and many more people live within range of Rainier and the rivers that flow from its glaciers (susceptible to lahars and pyroclastic flows) than St. Helens.

It is generally not believed that an eruption from Mount Rainier -- as with any Cascade volcano -- would not be as smooth and quiet as some of Hawaii's volcanoes, but there do seem to be more mountain-building eruptions (adding lava) than mountain-destroying eruptions (destroying the cone and leaving a crater).

Answer 5

Mount Rainier is known for having the potential for explosive eruptions due to its large volume of magma that can lead to significant ash and pyroclastic flow hazards. However, it is also possible for the volcano to have more quiet eruptions that primarily involve the effusion of lava flows.

Answer 6

Mt Rainier's last eruption was explosive it was not quiet

Answer 7

It is explosive
