volcanic eruption?

Question

could someone please tell me which is the largest volcanic eruption. some places list the lake toba one while others the tambora one and some the yellowstone one and also some as the la garita caldera one. which is actually the largest. a website would be helpful.

Answer 1

The biggest EVER?

Tambora was a tiddler, but the biggest in recorded history. Stratovolcanos (which Tambora is) generally just can't produce the really, really big eruptions.

Toba was large, as was the largest Yellowstone one (Huckleberry Ridge, I believe), but both were almost certainly smaller than the eruption at La Garita Caldera, so I'd say that one would be the biggest of the ones you listed.

However, if you include flood basalts, they would be the largest type of eruption, although they take place over very, very long periods of time, as opposed to the short eruptions of the 'supervolcanoes' and smaller ones.

Answer 2

You know what? I was just thinking about volcanoes today and looking up California's volcano map.

I looked up on google and found that the largest "active" volcano in the world would be Mauna Loa on the Big Island of Hawaii. Check this website for Mauna Loa's height and elevation and how much lava it spews out. http://www.extremescience.com/MaunaLoa.htm

Now, for a catastrophic volcanic eruption it would be The Yellowstone Volcano. See website details: http://volcanoes.usgs.gov/yvo/
It points out the lastest activity of seismic events. If this Volcano were to blow, it would be a eruption of biblical proportions. It would create a nuclear winter in the U.S. and many states surrounding that area will be under a cloud of volcanic ash and dust. You may have saw this on television as a movie, so you understand what devastation it can do.

Answer 3

major eruptions in the period June 1993 - June 1994:===

According to the Smithsonian Institution's Global Volcanism Network there was activity at about 45 volcanoes during that period. Perhaps the June 23, 1993, eruption of Unzen was most significant. Pyroclastic flows destroyed 187 homes and killed one person. Kliuchevskoi in Kamchatka, erupted explosively on July 15, 1993, sending ash to an altitude of 4.9 miles (7.8 km). On April 18, 1994, Lascar, in northern Chile, had its largest historical eruption, producing plinian columns 14 miles (22 km) above the crater and light ash fall in Buenos Aires, 900 miles (1500 km) to the southeast. There was continuous, or nearly continuous activity at Stromboli (Italy), Arenal (Costa Rica), Kilauea (Hawaii), Veniaminof (Alaska), Unzen (Japan), Sakura-jima (Japan), and Manam (Papua, New Guinea). In January of 1994, seismicity on the Juan de Fuca ridge was interpreted as a possible eruption on the sea floor.

Did you see that show on Supervolcanoes on National Geographic channel last night too? On a planetary scale everyone is screw
