Included are only fatalities from, at or above BC or caused from there. Fatalities on approach or return marches are not listed.
There are several different subsidiary peaks! Here are the geographical facts, from the one "relative independent Main-Peak" (EU category B) over the important subsidiary peaks (C) to the major notable points (D1) Especially the last category is just guessed by contours or from photographs.
Accordingly, the author introduced altitude classes (AC) and a proportional prominence, which he named orometrical dominance (D). D is calculated easily but fittingly: (P/Alt) x 100. Thus, it indicates the percentage of independence for every elevation, no matter what the altitude, prominence or mountain type it is. From a scientific point of view, altitude could be seen as the thesis, prominence as the antithesis, whereas dominance would be the synthesis.
A Nepali mountaineer and former British Marine has climbed the world's tallest 14 peaks in six months - beating an earlier record of almost eight years.
For every three thrill-seekers that make it safely up and down Annapurna I, one dies trying, according to data from Eberhard Jurgalski of website 8000ers.com, collected in his forthcoming book "On Top of the World: The New Millennium", co-authored by Richard Sale.

But a South Korean climber, who followed in their footprints on the crusted snow three days later [in 1997] in clearer weather, did not consider that they actually gained the top. While [Sergio] Martini and [Fausto] De Stefani indicated they were perhaps only a few meters below it, Park Young-Seok claimed that their footprints stopped well before the top, perhaps 30 meters below a small fore-summit and 150 vertical meters below the highest summit. Now in 2000 [Sergio] Martini was back again, and this time he definitely summited Lhotse.
But his claim to have now climbed all 8000ers is open to question. In April 1990 he and others reached the summit plateau of Cho Oyu. It was misty so they could not see well; nine years later Hinkes said he had "wandered around for a while" in the summit area but could see very little and eventually descended to join the others, one of whom said they had not reached the top.

: CS1 maint: numeric names: authors list (link)The most prominent one, Broad Peak Central is just 196m high and the least prominent, Lhotse Middle, is a meagre 60m. To put this in context, the highest mountain in Malta is 253m, while the Eiffel Tower stands a whopping 300m.
...the American climber became one of only five men in the world to accomplish the quest entirely without supplementary oxygen.
Last year, Silvio 'Gnaro' Mondinelli broke the haunted 13 when he summited the last peak on his list of 14, 8000ers – becoming only the 6th mountaineer in the world to have bagged them all without supplementary oxygen.
On October 29th, Nirmal Purja Magar announced via Instagram that he had summited China's Shishapangma. This marked the fourteenth 8,000-meter peak he had climbed in seven months and the completion of an extraordinary project to speed climb the world's tallest mountains in rapid succession.

Topographic criterium: for each summit, the level difference between it and the highest adjacent pass or notch should be at least 30 m (98 ft) (calculated as average of the summits at the limit of acceptability). An additional criterium can be the horizontal distance between a summit and the base of another adjacent 4000er.
