Right now we formed a forum about Lake Toba Sustainability. Our institution concerned about destruction in lake Toba. Most of us came from Bataknese and people who take attention seriously to Lake Toba Ecosystem. Indonesian goverment, especially North SUmatera province in march invite more than a houndred govenoor from all of the world. They plan to establish ne concept about Lake Toba in the future. But at the other side, the concept they have planed does not invite people in the ecosystem. we predict that mot of the masterplan does not conduct local sociocultural aspects. They just make Lake Toba as they want without hear public interest. we plan to make the similiar summit as the goverment planed to, but in different way. we plan to invite all local traditional leader to join a summit paralel with the goverment.
everybody who want joining our program will be invited.

I'm sorry but is this relevant to the page? It seems more like a propaganda of some sort [Unsigned]
The past Mount Toba, with ancient history.
Present, Lake Toba with more other history, with Samosir Island on the center.
Isn't same article.
The Toba catastrophe theory is linked to as the "main article" in the eruption section. The problem is that that article isn't really about the eruption but the theory of the eruption's impact on the development of man. As such, the article should be mentioned, but not as the main article with respect to that section. -Harmil 07:24, 6 October 2006 (UTC)
"toba" is Spanish for tuff. I suspect it is a coincidence, but what is the Indonesian meaning? --84.20.17.84 13:04, 23 January 2007 (UTC)
Somebody has stated that this (Young Toba eruption) is the biggest in the last in the last 2 million years. I have looked for bigger eruptions futher back and so far no eruption has surpassed it since around 27 million years ago so doesn't that make it the biggest volcanic eruption in the last 25 million years?

suggested) (help)Well seeing as no explosive eruption since La Garita has surpassed Toba I'll put that in. Wiki235 13:05, 8 July 2007 (UTC)
Somebody has put in that it was possibly the largest explosive vlcanic eruption withtin the history of the earth. This is incorrect. The eruption produced 2800 cubic km of material where as the La Garita eruption 27.5 million years ago produced 5000 cubic km which makes it larger. Please don't add claims that are not true.Wiki235 (talk) 20:54, 20 November 2007 (UTC)
Why is one of the photographs in the article captioned 'Lake Toba from the island of Prapat?' The maps I see show Prapat being on the periphery of the lake, not an island. Deedeebee (talk) 20:13, 1 February 2008 (UTC)
This article is now out-of-date. Its references to having caused a global cool down an being responsible for killing much of humanity has been proven wrong.

GA review – see WP:WIAGA for criteria
This article is in decent shape, but it needs more work before it becomes a Good Article.

It would be good to make it clear, in the infobox, whether the surface area includes or excludes Samosir, e.g. "area = 1,130 km² (excluding Pulau Samosir)". --Chriswaterguy talk 20:00, 24 August 2008 (UTC)
"scientists believe might have wiped out much of civilization." As far as we know, there were no civilizations 75,000 years ago. I'm being WP:BOLD and changing it to "much of humanity"; if this is wrong for some reason or you have a better wording, please change it. Vultur (talk) 00:09, 29 August 2008 (UTC)
I asked this a year ago but there's been no explanation or correction, so I will ask it again-Why is one of the photographs in the article captioned 'Lake Toba from the island of Prapat?' The maps I see show Prapat being on the periphery of the lake, not an island? Deedeebee (talk) —Preceding undated comment was added at 22:41, 31 January 2009 (UTC).
I've changed the line in the lead paragraph from "it is the site of a supervolcanic eruption that occurred 75,000 years before the present" to "...that occurred 74,000 years before the present", as this is what the sources used in the article agree on Dom Kaos (talk) 22:46, 15 June 2009 (UTC)

Look I'm sick of people changing this page, stating that this eruption was the largest of any kind anywhere in the last 25 million years. It wasn't. The Columbia River Basalt Group which began around 14 MYA and lasted up until 6 MYA were far, far larger than Lake Toba. If we restrict the statement to explosive eruptions then it's fine, but in it's present state it's not. I'll change it to explosive eruptions, if you want to change it back and have proof that this eruption exceeded the 174,300 km³ erupted by the Columbia River Basalt Group i.e. an article by a geologist which states this eruption exceeds VEI 8 and is infact the VEI 10 it would need to be to support the statement, then please provide the evidence. If you don't understand, either leave me a message or talk to one of the senior members of WikiProject Volcanoes. Thank you. Wiki235 (talk) 22:12, 14 July 2010 (UTC)
The two words in the lead, "largely debated", caught my eye. The article reads, "According to the Toba catastrophe theory to which some anthropologists and archeologists subscribe, it had global consequences, killing most humans then alive and creating a population bottleneck in Central Eastern Africa and India that affected the genetic inheritance of all humans today.[5] This theory however, has been largely debated as there is no evidence for any other animal decline or extinction, even in environmentally sensitive species.[6]" But what % of anthropologists and archeologists subscribe to this theory? It sounds like it could be a minority view. The source[2] for the last sentence concludes "We conclude that it is unlikely that the Toba super-eruption caused a human, animal or plant population bottleneck." I don't think "largely debated" tells us much about what mainstream scholars think. Jesanj (talk) 00:51, 24 June 2011 (UTC)
The photo named Ambarita2.jpg has an error in editing. This image was created from a set of overlapping images and there is an error in the middle of the photo. There's a large section that is duplicated, as if the two images were pasted together in the wrong place. I did a tentative correction eliminating the redundant pixels that resulted in an image 4254 pixels wide vs. the 5208 pixels of the image as posted here. Vhilden (talk) 11:15, 22 January 2012 (UTC)
This sentence contains a conversion error:
'It has been accepted that the eruption of Toba led to a volcanic winter with a worldwide decrease in temperature between 3 to 5 °C (5.4 to 9.0 °F), and up to 15 °C (27 °F) in higher latitudes.'
15 °C is 59 °F — Preceding unsigned comment added by 216.215.153.86 (talk) 19:30, 4 October 2014 (UTC)
"This study support by Lane and Zielinski. Lane and Zielinski studied the lake-core from Africa and GISP2. Lane had prove that no volcanic winter after Toba eruption, and Zielinski prove that high H2SO4 deposit does not cause long-term effect.[15][16]"
Can a native speaker correct this? Thanks. — Preceding unsigned comment added by 131.130.153.43 (talk) 14:58, 18 September 2015 (UTC)

Is average depth really 500 m? How was this calculated? With a maximum depth of 505 m this would indicate a prism/cylindrical shape more perfect than your average kitchen pot, fairly unlikely for a volcanic lake. Dividing volume 240 km3 by surface 1130 km2 we get a much more realistic (for your average vaguely inverted-cone-shaped volcanic caldera) 210 m average depth. 93.142.85.96 (talk) 00:53, 25 February 2018 (UTC)

Per Sinking_of_MV_Sinar_Bangun#22_June, the lake apparently turned out to be much deeper than previously thought. So the max. depth of 505 m given here seems to be outdated. Gestumblindi (talk) 23:26, 29 June 2018 (UTC)
Please, correct the intro. The country the lake is located in wasn't even specified in the first sentence. I have corrected it now, but it's still a mess. Should the first sentence talk about the calderra of a supervolcano? Can't the location be summarised at the beginning, and the geological nature be followed up on later?--Adûnâi (talk) 21:27, 30 June 2018 (UTC)
I suggest that The Origin of Lake Toba does not seem sufficiently notable for a standalone article but if it can be better sourced would be a useful addition to the article on the Lake, so that stub should be merged into this article. PamD 16:12, 6 April 2021 (UTC)
