Was the eruption's devastating effect on Europe a contributing factor to British surrender?
Sean7phil ( talk) 02:17, 23 March 2010 (UTC)
Well, although the fissures are only recorded to erupt once, I belive they may once more erupt, or the lava may even find its way to the mountian itself....The Laki Fissure Erutions of 1783-1784 are very interesting. The effects on weather went as far as freezing over the Missisippi River at New Orleans, and allowing ice skating at the Charleston Harbor.if the Laki fissures erupt agian, the effects on the entire world will be extravigant.
Benjamin Franklin is quoted "... that other volcano which arose out of the sea near that island..." Was this part of Vestmannaeryjar and the dozen or so lumps stretching to the mainland and Surtsey ? I can't find any detail on Google.
25%–33% seems to give a very precise range for what I suspect is an approximation for the fraction of the population killed in the 1780s eruption. Perhaps a quarter to a third might be better wording. Bazza 13:26, 20 April 2007 (UTC)
Is this right? I can't see the causation between a surplus harvest and poverty.-- Malcohol 14:03, 20 April 2007 (UTC)
Grain is both a sustenance and cash crop. A surplus harvest decreases prices for grain. Large/local estates can supply all the grain the cities need, so the 'cash saleable component' of the small farmers' harvest is either 'not required' by the market or sold at significantly lower price. Not forgetting that the landlords also owned or dominated both the processing (wind-mills) and distribution (horses and carts) chains. Only from a consumer-centric or urban viewpoint are surpluses an unalloyed 'good thing'. Autodidactyl 12:03, 21 April 2007 (UTC)
You've answered your own question.. A surplus would drop the prices so low that farmers living on the already thin margins would receive relatively nothing for their crops and then begin to starve. Not everyone worked the 'sharecroppers' life in Europe at that time though many were in servitude. Land barons still wanted their rents and when the markets were flooded with plenty of everything that never lasts very long. Produce is perishable and always has been, but prices once they drop tend to stay that way for quite some time until all the stores stocks run out. In the meantime people starved. —Preceding

"Laki is part of a volcanic system, centering on the Grímsvötn volcano and including the Eldgjá canyon, Thórdarhyrna and Katla volcanos." This statement was here unreferenced and unchallenged before my wikipedia time. User Brigt ( talk • contribs) challenged it, as IP address and as his first contribution. Without references to support it, at first.
GVP states the Laki fissure belongs to the central volcano Grímsvötn and that the Eldgjá canyon belongs to the Katla volcano. Strangely, Laki is southernly as Eldgjá. The image draws these two systems separated, citing pages 12-13 of Surtsey Nomination Report 2007. Actually T. Thordarson and G. Larsen (2007) has a similar picture. User Brigt claims "Iceland : Katla Volcano". Iceland on the web. Retrieved 2010-03-26. is a tourist information page and it is citing wikipedia.

I was attempting to verify whether people generally measured temperature reliably over an area as large as New England when the fisure occured. The reference says (and is quoted here) that this was the longest period of sub-zero weather (Fahrenheit assumption?) in that area. Is this a reliable statement? Couldn't find anything to support it in my favorite reference work, Wikipedia! :) Partially the fault of our fellow-editors who are more interested in individuals than in general use history. Student7 ( talk) 12:08, 31 March 2010 (UTC)
To keep track of the temperature is something quite recent. Below zero means below freezing, rather here, I bet. -- Chris.urs-o ( talk) 12:27, 31 March 2010 (UTC)
"Below zero" - Fahrenheit or Celsius? My guess is Fahrenheit, but I may be wrong and don't want to include guesswork in Wikipedia. Floozybackloves ( talk) 03:37, 8 June 2012 (UTC)
Almost invariably Fahrenheit, but thermometers were produced by various sources and not all used the freezing and boiling points accurately hence the graduations could be misaligned. This can be shown in many recordings made a few miles apart which showed large discrepancies in temperature. Now all thermometers are supposedly produced to the same standard and almost invariably the scientific world uses either Celsius or Kelvin. In 1784 the temperatures used were amogst others Fahrenheit, Centigrade - defined by Celsius as being 100 points between the freezing point - 0 and 100 boiling point of water. The Geologist ( talk) 18:20, 9 December 2012 (UTC)
Is there another reference for the claims of numbers of persons killed due to the eruption? I have seen these numbers propagated on lists of deadly natural disasters referencing this article, and to find these eye catching numbers are linked to a History Channel citation is a bit, well, unscholarly. — Preceding unsigned comment added by 75.74.198.85 ( talk) 13:39, 11 June 2011 (UTC)

120,000,000 long tons is 121,925,629.056 tonnes, so it ought to be rounded to 122,000,000 tonnes; I was going to fix that because it looks stupid as it is, but I see that the conversion is automated. Not sure what's going wrong. 64.71.2.189 ( talk) 19:50, 8 June 2012 (UTC)

Yeah, RacerX, you're right. But I have since discovered that there were other things, also massive, happening at the end of the 18th century. So there is probably no relationship between this particular event and that rise. 58.166.81.234 ( talk) 11:17, 8 June 2013 (UTC)
I watched a documentary on WNED Buffalo tonight (10:00 PM June 12, 2013) entitled "Nature's Power Revealed: Power of Fire".

The section “1783 eruption” first states that the eruption rated at 4, but in the next paragraph states that it was rated at 6.
The Global Volcanism Program says it was a VEI 4 on their page, under Grímsvötn eruption history. ZFT ( talk) 21:35, 15 May 2018 (UTC)
Should the 1783 eruption be given its own article? This one seems like a no brainer, it's a significant historical eruption and the section on this eruption is very long. Mrmp2402 ( talk) 07:58, 6 August 2022 (UTC)
