Talk:Toba eruption

Merge
Yes they must be joined. It gives a more complete profile of lake Toba. (Comment added by anon user User:69.68.51.41 01:39, 27 December 2005)

No! The article about the lake is about a lake that exists today. The eruption happened long ago. The existing link is the perfect way to link the two. Peak 01:08, 31 December 2005 (UTC)


 * Definitely should not be merged, for the reason stated above. bob rulz 20:37, 5 January 2006 (UTC)

PLEASE don't merge
To put it simply, both the lake and the eruption are significant in many ways and deserve their seperate spaces.AndyinMN 09:57, 22 January 2006 (UTC)

Not merge. The eruption had many more profound effects other than the enlargement of the lake. The lake was probably there before the most recent caldera forming eruption in any case since the Toba depression is made of at least three overlapping calderas (see Eruptive History section in ). Equally, the lake has many features which are not related to this particular eruption, for example the settlements around it and the ecology. They are both big subjects in their own right.

28 million years
The uncertainties on the volumes of these eruptions are so large that it makes no sense to insist that Toba was the largest of the last 28 million years. The 2.1 million year Yellowstone eruption was comparable, and there are others that could be that large. Rarely if ever is there sufficient preservation of the deposits to accurately calculate volumes. (Comment added by anon user User:130.118.37.12 22:27, 6 January 2006)


 * The 28 million years claim probably came from . That actually refers to it as the largest volcanic cataclysm, whatever that might be, rather than the largest eruption; and has a diagram showing a 28 million year old eruption at Fish Canyon, Colorado as slightly larger and the 2.1 million year old Yellowstone one as slightly smaller. I have changed the article to describe the Toba eruption as the largest within 2 million years, as there are plenty of references to this and it acknowledges possible error in determining the amount of material erupted. The 180,000 cubic kilometre Columbia River flood basalt province, mostly erupted about 16 million years ago, contains some flows which may be between 2000 and 3000 cubic kilometres, further muddying the 28 million year question if  largest volcanic cataclysm means the most material in an eruption.
