It should be noted that this is a short term release of energy. Keep in mind that basalt flood eruptions could release more energy as well. My take is that the Deccan traps and the
Columbia River flood basalt eruptions would have released much more energy, perhaps even more than the Chicxulub impact,

Someone has stated that a new system is needed. I agree because what have clearly been defined as the largest eruptions in the earth's history are being rejected by the VEI system.If a system that judged both kinds of eruptions existed then we could clearly see which are the largest eruptions and
394:
Chicxulub may have released 4Ă—1023 joules of energy, equivalent to 100,000,000 megatons of TNT on impact. The Tsar Bomba, was 50 megatons. The
Chicxulub impact was 2 million times more powerful. La Garita, at approximately 1021 joules, was less powerful.
436:
The article makes a comparison between the largest nuclear bomb ever detonated, and this eruption, but uses completely incompatible units for comparison. This should either be removed, or the units converted to something that makes sense.
346:
I second this comment; there have been impacts larger than the
Chicxulub. The Vredefort and Sudbury impacts may be the only ones with known craters, but there must have been many more during the Late Heavy Bombardment.
219:
VEI measures eruption sizes based on volume of magma erupted in cubic km and eruption column height. Magnitude, as used in the article by Mason et al, measures eruption size based on mass of magma erupted in kilograms.
404:
The Tsar Bomba, had a yield of 50 megatons; La Garita was approximately 100,000 times more powerful. It is possibly the most energetic event on Earth since the
Chicxulub impact, which was 50 times more powerful.
460:
I'm inclined to agree with you. It might be better to compare with other volcanic events. One possibility is Savino & Jones ("Supervolcano: The
Catastrophic Event That Changed the Course of Human History"

211:
does it state that the FC Tuff had a high volume as this. In fact, it's still stated as 5,000 cubic km in that article. Because the erupted volume is under 10,000 cubic km, it is still a VEI-8 eruption
921:
The entire discussion about the size of the eruption vs the Tsar Bomba is un-cited, and probably incorrect given the whole claim. This needs to be fixed with proper citations or deleted.

Regarding the phrase "It is possibly only the second most energetic event to have ocurred on Earth besides the
Chicxulub impact", what about the impact that formed the moon? Or the

Someone has stated that the Fish Canyon Tuff from La Garita
Caldera was a VEI-9 eruption and that the volume was 18,000 cubic km. Both are inaccurate. Nowhere in the article

but that energy would have been released over a longer time. And I imagine that there's eveb more energy involved in the acceleration of a major continental plate. --

But compare the number of joules given: 10 to the 21 joules and 4 * 10 to the 23 joules; Chicxulub was 400 times more powerful than La Garita, not 50.
