I am trying to fill in a Selected Anniversary for April 10; in so doing, I found the Mount Tambora article which currently states that April 10 was the climactic day. However, April 15 also is credited as the big day. Based on the page history, April 10 appears to be the consensus. If there are no objections, I would like to cite this day in Selected anniversaries. Ancheta Wis 13:14, 7 Mar 2004 (UTC) Mav, sorry for the misunderstanding on the number of allowed events per day.

Given that there seems to be little to add to this article and given that all of the legitimate changes in the past month have been reverts of vandalisms, both childish and subtle, is it worthwhile to ask for a vandalism-lock on this page? Ddama 18:46, 18 December 2005 (UTC)
I was reading about the recent possible discovery of the extinct civilization of Tambora in "Scientists Claim to Find Lost Civilization" ( AP via Yahoo! News, February 27, 2006), and as usual went to Wikipedia to read up on what was known. Apparently nothing! We have no article on them, and this article on the eruption that killed the island population makes no direct reference to this terrible death of an entire people. (It just mentions in "Effects" a total death count similar to what the news article gives. Neither relate this number to the Tamborans.) Can we dig up some existing information about these people and add their extinction, a fairly significant event, to this article? Perhaps we'll eventually be able to create an article for the people from this. ~ Jeff Q (talk) 04:14, 28 February 2006 (UTC)
While the main article gives April 10-15 for the time of the Tambora eruption, the last quote appears to ascribe the events to the July 11-15 time frame. If the quote is accurate, this discrepancy deserves explanation. I also agree that quotes should be sourced.

I moved the unsourced looong quotes here. If somebody knows their sources, then we can put them back into the article.
== Quotes from 1815 accounts of the eruption ==
=== Explosion ===
"The concussions produced by its explosions were felt at a distance of a thousand miles (1600 km) all round; and their sound is said to have been heard even at so great a distance as seventeen hundred miles (2700 km). In Java the day was darkened by clouds of ashes, thrown from the mountain to that great distance (300 miles or 500 km), and the houses, streets, and fields, were covered to the depth of several inches with the ashes that fell from the air. So great was the quantity of ashes ejected, that the roofs of houses forty miles (65 km) distant from the volcano were broken in by their weight. The effects of the eruption extended even to the western coasts of Sumatra, where masses of pumice were seen floating on the surface of the sea, several feet in thickness and many miles in extent."
=== Pyroclastic flow ===
"From the crater itself there were seen to ascend 3 fiery pyroclastic columns, which, after soaring to a great height, appeared to unite in a confused manner at their tops. Soon, the whole of the side of the mountain next to the village of Sang'ir seemed like one vast body of liquid fire. The glare was terrific, until towards evening, when it became partly obscured by the vast quantities of dust, ashes, stones, and cinders thrown up from the crater. Between nine and ten o'clock at night the ashes and stones began to fall upon the village of Sang'ir, and all round the neighbourhood of the mountain."
=== Atmospheric disturbance ===
"The heat triggered a 'dreadful whirlwind', which blew down nearly every house in the village, tossing the roofs and lighter parts high into the air. In the neighbouring sea-port the effects were even more violent, the largest trees having been torn up by the roots and whirled aloft. Before such a furious tempest no living thing could stand. Men, horses, and cattle were whirled into the air like so much chaff, and then dashed violently down on the ground. The sea rose nearly twelve feet above the highest tide-mark, sweeping away houses, trees, everything within its reach. This whirlwind lasted about 19 seconds."
=== Gradual decrease ===
"The 'awful internal thunderings of the mountain' continued with scarcely any intermission until the 11th of July, when they became more moderate, the intervals between them gradually increasing until the 15th of July, when they ceased. Almost all the villages for a long distance round the mountain were destroyed. By far the greatest part of this destruction was wrought by the violence of the whirlwind which accompanied the eruption."
The chronology section mentions "thunderous detonations". I suspect this is referring to the noise rather than the electrical phenomenon thunder. Yet the article links to thunder. If it only is describing the noise, then it should be delinked, or even an alternative found. -- Merbabu 12:00, 27 October 2006 (UTC)

The geological information section states tambora was: 'the only VEI 7 since AD 1400.' According to the Volcanic Explosivity Index page, the next most recent 7 was Taupo in AD 181. Which eruption is this refering to? I'm guessing Kuwae but that's listed as a VEI 6. This should be sorted out & probably linked.
The 'magnitude' collumn in the comparson table later in the section is also a little awkward. First, it never states magnitude of what, and second, the scientific notation values are difficult to compare at a glance - inclusion of the VEI rating would be helpful. -- Spyforthemoon 21:42, 7 November 2006 (UTC)
Wasn't Krakatoa the most violent eruption in modern history? Sound was heard from a greater distance and global temperatures lowered even more so that Tambora. Tambora ony killed more because of neighboring population. But as for the "largest explosion", Krakatoa was the largest, loudest, and affected global temperatures more so. The "deadliest" volcano was Tambora related to a soon after starvation of people. —Preceding unsigned comment added by 71.106.3.162 ( talk • contribs)
The difference between Tambora exploding in 1815 and Krakatau in 1883 is the fact that few people outside of Indonesia were aware of the Tambora eruption for many months as news at that time took months to reach places like London, Paris, New York due to it being carried by sailing ships. However when Krakatau exploded the news went around the world courtesy of the telegraph in a matter of hours. Tambora probably was a more powerful explosion than Krakatau but it cannot be scientifically proved. 86.156.178.15 ( talk) 16:42, 5 April 2012 (UTC) I didn't realise that I wasn't logged in when I wrote the above. Apologies. The Geologist ( talk) 16:55, 5 April 2012 (UTC)
How is Tambora existence is estimated around 57 ka BP,[6] supposed to read? It's been reverted, so I'm must have guessed wrong. But right now it just doesn't make any sense - I mean gramtically, I'm not a geologist, so I don't know if it makes sense scientifically.
I assume 'Tambora existence' is supposed to be 'Tambora's existence' or 'The existence of Tambora'. Is this right?
57 ka BP seems to be a year, but elsewhere in the article we use AD/CE dates. Why is it different here?
Also, the main verb is currently 'is estimated'. If you move the prepositional phrase and the passive voice you get: around 57 ka BP someone estimated tambora existence This can't be right. Is the existence estimated to have begun then? Something else?
I appreciate help in getting this clear. -- Spyforthemoon 19:15, 10 November 2006 (UTC)

I have reverted this number two times. To any editors who have read a source, please read first Mount_Tambora#Aftermath section. There is the explanation about different numbers. The source comes from:
where Oppenheimer explains why there are different number of deaths. The safe number is > 71,000. The figure 92,000 comes from unfounded and based untraceable references. See this article:

This section states that Average global temperatures decreased about 0.4–0.7°C (32–33°F). This is wrong, a decrease of 0.4 C is not a decrease of 32 F. A temperature of 0.4 C is equivalent to 32 F, but that is not what the sentence is talking about. -- Alonso 05:28, 26 December 2006 (UTC)

How is this accurate? "Agricultural crops failed and livestock died in much of the Northern Hemisphere, resulting in the worst famine of the 19th century.[4]" since the death total mentioned is 200,000. And there were a million odd deaths from the potato famien in Ireland in the mid 18th century. —Preceding unsigned comment added by 89.234.125.89 ( talk) 23:01, 23 October 2008 (UTC)
If you look at hard evidence it is difficult to prove, but scientific evidence supports the claim that the death toll in the northern hemisphere increased by at least 10% of the expected. Logs of the Royal Navy - for the pedantics there is only one Royal Navy all others are Royal **** Navy, over the period 1814 - 1817 indicate that the temperature in 1816 dropped over the whole of the North Atlantic and most of the South Atlantic. These records are available for inspection at the National Archives in London. In 1816 many European records state that in the growing season of 1816 "Cold unremitting rain fell without pause. Crops failed to grow, rotted in the ground because the could not be harvested." When the death records of the previous and following years are compared there was a large unexplained increase in mortality, animals starved because the fields produced no grass and therefore no hay. The only common factor in all the phenomena is Tambora. The Geologist ( talk) 16:55, 5 April 2012 (UTC)
Although distance is in the previous reference, it is, as well, needed f/ this phrase, please.
" It took centuries to refill the magma chamber,...":
Is there an estimate as to when????
Thank You, [[ hopiakuta Please do sign your signature on your message. ~~ Thank You. -]] 01:40, 3 December 2007 (UTC)
How long is a piece of string? As a volcanologist it is a question we are often asked but we have no hard and fast answer. At Mount St Helens in 1980 the magma had been rising for some time before the initial eruption of March 1980. That was the first indication that the volcano was becoming active, by 18th May 1980 sufficient magma had entered the edifice to cause it to be de-stabilised and the explosion was then inevitable. Krakatau exploded in August 1883, yet it now protrudes above sea level and is growing at about 5 m per year in height. Estimates vary from a few cubic metres yearly to a few hundreds of cubic metres. So think of a number and you will be no more right than anyone else. Have fun. The Geologist ( talk) 17:01, 5 April 2012 (UTC)
Well try this 1.6 x 1011 cubic metres can also be written as 160000000000 cubic metres which is equal to a cube 5429 x 5429 x 5429 metres, or a cube whose sides measure ~17611 feet which is equivalent to a cube whose sides measure ~ 3.4 miles. If you want to know how big a landmass is involved buried by 100 metres of tephra then do the maths. The Geologist ( talk) 17:22, 20 May 2014 (UTC)
Using only Wikipedia based sources, the 1815 eruption appears to be largest volcanic eruption in the past ~11,000 years in terms of tephra volume. I was unable to find a larger eruption more recent than 12,000 years ago, Campi Flegrei in Italy (200-300 cubic km). I need more research to back it up but this would be an excellant addition to the article. I'll work on it, if someone could help me out it'd be great. -- Hurricane ERIC - Class of '08: XVII Maius MMVIII 01:02, 19 June 2008 (UTC)
WEll i need more info about the longitude and latitude please? —Preceding unsigned comment added by 169.139.224.147 ( talk) 19:07, 2 March 2010 (UTC)
Hatepe eruption of 180AD was comparable to Tambora, estimated at 120 cubic km vs Tambora's 160. But estimates of such a thing are prone to large amounts of error. Cadwallader ( talk) 23:29, 7 May 2010 (UTC)
As Cadwallader says when a volcano erupts we then have to try and calculate how much material has been erupted - relatively easy if its basaltic lava plus volatile equals approximately 100%. However, when a volcano like Tambora explodes we have a problem. There is usually no or very little lava as lava, it is usually ejected as pumice, tephra etc, rises into the stratosphere and is carried away by the wind. Eventually it falls back to the ground which may be on land but often is out at sea meaning it is effectively lost. So what we do is measure the hole and arrive at a volume, add the pre-explosion height and calculate that volume, which gives some idea of the mass that has vanished. We use other factors too to cover the uncertainty of what we are missing and eventually a consensus is arrived at - which will inevitably vary from one scientist to another, but that aside it will be in the right order of magnitude. Incidentally the difference between the Hatepe and Tambora is about 40 cubic kilometres or a block less than 4 x 4 x 4 km. Hatepe and Tambora are both in the same order of magnitude and erupted similar volumes of material - DRE. The Geologist ( talk) 17:33, 24 January 2013 (UTC)
This line is rather ridiculous in the greater context of the article:
Given that 100% of the vegetation on the island was completely destroyed by the eruption of Tambora in 1815, and this rain forest and all of its animals grew from nothing since then, it seems rather ridiculous to say that logging threatens the rain forest. Tambora is the greatest threat to the rain forest. But the rain forest was able to overcome it and grow back. Logging is just a minor hair cut in comparison. Cadwallader ( talk) 23:29, 7 May 2010 (UTC)
For a featured article, I was surprised to see this has a mix of Br Eng and Am Eng spelling:
From the preponderence of spellings I'd guess the WP:ENGVAR that was origianlly used for this page was Br Eng, and it has got corrupted by the addition of some Am Eng spellings, but that's just a guess. Whatever is the Engvar of choice, it should be sorted so that the page uses one for the other, not both. 86.133.55.238 ( talk) 13:48, 10 April 2011 (UTC)
Actually "Meters" is the USA spelling, the rest of the world spells the word "METRES," and the rest of the world does use "meters" as a word to indicate a gauge such as a "Gas meter, water meter, electric meter," but kilometres is 1000 metres. The Geologist ( talk) 17:05, 5 April 2012 (UTC)
The article linked to is of very, very poor quality and contains far, far less information than we see here. Suggest remove link until that article is up to stantard. Or just delete it it is useless. — Preceding unsigned comment added by 156.22.9.252 ( talk) 04:27, 24 January 2013 (UTC)

The "deadliest" volcano was Tambora related to a soon after starvation of people. —Preceding unsigned comment added by 71.106.3.162 ( talk • contribs)
The difference between Tambora exploding in 1815 and Krakatau in 1883 is the fact that few people outside of Indonesia were aware of the Tambora eruption for many months as news at that time took months to reach places like London, Paris, New York due to it being carried by sailing ships. However when Krakatau exploded the news went around the world courtesy of the telegraph in a matter of hours. Tambora probably was a more powerful explosion than Krakatau but it cannot be scientifically proved. 86.156.178.15 ( talk) 16:42, 5 April 2012 (UTC) I didn't realise that I wasn't logged in when I wrote the above.

How is Tambora existence is estimated around 57 ka BP,[6] supposed to read? It's been reverted, so I'm must have guessed wrong. But right now it just doesn't make any sense - I mean gramtically, I'm not a geologist, so I don't know if it makes sense scientifically.
I assume 'Tambora existence' is supposed to be 'Tambora's existence' or 'The existence of Tambora'. Is this right?
57 ka BP seems to be a year, but elsewhere in the article we use AD/CE dates. Why is it different here?
Also, the main verb is currently 'is estimated'. If you move the prepositional phrase and the passive voice you get: around 57 ka BP someone estimated tambora existence This can't be right. Is the existence estimated to have begun then? Something else?
I appreciate help in getting this clear. -- Spyforthemoon 19:15, 10 November 2006 (UTC)

I have reverted this number two times. To any editors who have read a source, please read first Mount_Tambora#Aftermath section. There is the explanation about different numbers. The source comes from:
where Oppenheimer explains why there are different number of deaths. The safe number is > 71,000. The figure 92,000 comes from unfounded and based untraceable references. See this article:

This section states that Average global temperatures decreased about 0.4–0.7°C (32–33°F). This is wrong, a decrease of 0.4 C is not a decrease of 32 F. A temperature of 0.4 C is equivalent to 32 F, but that is not what the sentence is talking about. -- Alonso 05:28, 26 December 2006 (UTC)

How is this accurate? "Agricultural crops failed and livestock died in much of the Northern Hemisphere, resulting in the worst famine of the 19th century.[4]" since the death total mentioned is 200,000. And there were a million odd deaths from the potato famien in Ireland in the mid 18th century. —Preceding unsigned comment added by 89.234.125.89 ( talk) 23:01, 23 October 2008 (UTC)
If you look at hard evidence it is difficult to prove, but scientific evidence supports the claim that the death toll in the northern hemisphere increased by at least 10% of the expected. Logs of the Royal Navy - for the pedantics there is only one Royal Navy all others are Royal **** Navy, over the period 1814 - 1817 indicate that the temperature in 1816 dropped over the whole of the North Atlantic and most of the South Atlantic. These records are available for inspection at the National Archives in London. In 1816 many European records state that in the growing season of 1816 "Cold unremitting rain fell without pause. Crops failed to grow, rotted in the ground because the could not be harvested." When the death records of the previous and following years are compared there was a large unexplained increase in mortality, animals starved because the fields produced no grass and therefore no hay. The only common factor in all the phenomena is Tambora. The Geologist ( talk) 16:55, 5 April 2012 (UTC)

" It took centuries to refill the magma chamber,...":
Is there an estimate as to when????

How long is a piece of string? As a volcanologist it is a question we are often asked but we have no hard and fast answer. At Mount St Helens in 1980 the magma had been rising for some time before the initial eruption of March 1980. That was the first indication that the volcano was becoming active, by 18th May 1980 sufficient magma had entered the edifice to cause it to be de-stabilised and the explosion was then inevitable. Krakatau exploded in August 1883, yet it now protrudes above sea level and is growing at about 5 m per year in height. Estimates vary from a few cubic metres yearly to a few hundreds of cubic metres. So think of a number and you will be no more right than anyone else. Have fun. The Geologist ( talk) 17:01, 5 April 2012 (UTC)
Well try this 1.6 x 1011 cubic metres can also be written as 160000000000 cubic metres which is equal to a cube 5429 x 5429 x 5429 metres, or a cube whose sides measure ~17611 feet which is equivalent to a cube whose sides measure ~ 3.4 miles. If you want to know how big a landmass is involved buried by 100 metres of tephra then do the maths. The Geologist ( talk) 17:22, 20 May 2014 (UTC)
Using only Wikipedia based sources, the 1815 eruption appears to be largest volcanic eruption in the past ~11,000 years in terms of tephra volume. I was unable to find a larger eruption more recent than 12,000 years ago, Campi Flegrei in Italy (200-300 cubic km). I need more research to back it up but this would be an excellant addition to the article. I'll work on it, if someone could help me out it'd be great. -- Hurricane ERIC - Class of '08: XVII Maius MMVIII 01:02, 19 June 2008 (UTC)

Hatepe eruption of 180AD was comparable to Tambora, estimated at 120 cubic km vs Tambora's 160. But estimates of such a thing are prone to large amounts of error. Cadwallader ( talk) 23:29, 7 May 2010 (UTC)
As Cadwallader says when a volcano erupts we then have to try and calculate how much material has been erupted - relatively easy if its basaltic lava plus volatile equals approximately 100%. However, when a volcano like Tambora explodes we have a problem. There is usually no or very little lava as lava, it is usually ejected as pumice, tephra etc, rises into the stratosphere and is carried away by the wind. Eventually it falls back to the ground which may be on land but often is out at sea meaning it is effectively lost. So what we do is measure the hole and arrive at a volume, add the pre-explosion height and calculate that volume, which gives some idea of the mass that has vanished. We use other factors too to cover the uncertainty of what we are missing and eventually a consensus is arrived at - which will inevitably vary from one scientist to another, but that aside it will be in the right order of magnitude. Incidentally the difference between the Hatepe and Tambora is about 40 cubic kilometres or a block less than 4 x 4 x 4 km. Hatepe and Tambora are both in the same order of magnitude and erupted similar volumes of material - DRE. The Geologist ( talk) 17:33, 24 January 2013 (UTC)
This line is rather ridiculous in the greater context of the article:
Given that 100% of the vegetation on the island was completely destroyed by the eruption of Tambora in 1815, and this rain forest and all of its animals grew from nothing since then, it seems rather ridiculous to say that logging threatens the rain forest. Tambora is the greatest threat to the rain forest. But the rain forest was able to overcome it and grow back. Logging is just a minor hair cut in comparison.

For a featured article, I was surprised to see this has a mix of Br Eng and Am Eng spelling:
From the preponderence of spellings I'd guess the WP:ENGVAR that was origianlly used for this page was Br Eng, and it has got corrupted by the addition of some Am Eng spellings, but that's just a guess. Whatever is the Engvar of choice, it should be sorted so that the page uses one for the other, not both. 86.133.55.238 ( talk) 13:48, 10 April 2011 (UTC)
Actually "Meters" is the USA spelling, the rest of the world spells the word "METRES," and the rest of the world does use "meters" as a word to indicate a gauge such as a "Gas meter, water meter, electric meter," but kilometres is 1000 metres. The Geologist ( talk) 17:05, 5 April 2012 (UTC)
