"It almost looks like a torando, this vertical column of flame" "Reported since Tokyo fire in 1943 - 40,000 deaths" >> reminds me of horizontal candle burning when between electric plates https://en.wikipedia.org/wiki/Fire_whirl Firewhirls were produced in the conflagrations and firestorms triggered by firebombings of European and Japanese cities during World War Two and by the atomic bombings of Hiroshima and Nagasaki. Firewhirls associated with the bombing of Hamburg, particularly those of 27–28 July 1943, were studied.[19] Most of the largest fire whirls are spawned from wildfires. They form when a warm updraft and convergence from the wildfire are present.[4] They are usually 10–50 m (33–164 ft) tall, a few meters (several feet) wide, and last only a few minutes. Some, however, can be more than 1 km (0.6 mi) tall, contain wind speeds over 200 km/h (120 mph), and persist for more than 20 minutes.[5] Fire whirls can uproot trees that are 15 m (49 ft) tall or more.[6] These can also aid the 'spotting' ability of wildfires to propagate and start new fires as they lift burning materials such as tree bark. These burning embers can be blown away from the fireground by the stronger winds aloft. An extreme example of a fire whirl is the 1923 Great Kantō earthquake in Japan, which ignited a large city-sized firestorm and produced a gigantic fire whirl that killed 38,000 people in fifteen minutes in the Hifukusho-Ato region of Tokyo.[17] https://www.sciencedirect.com/science/article/pii/S0263224117306474 Magnetic field associated with an internal fire whirl: A simple model C.H.Cheng(a), S.S.Han(a), W.K.Chow(a), C.L.Chow(b) A fire whirl can be generated by a pool fire in vertical shafts in tall buildings under certain ventilation conditions. Internal fire whirls are much more dangerous and destructive than non-whirling fires in the shaft and deserve more attention. As fires or flames consist of ions in motion, the characteristics of the magnetic field generated by a fire whirl would provide important information. The present study aims at measuring the magnetic field generated by a fire whirl and at building a simple model to explain the generated magnetic field. The physical origin of the magnetic field associated with a fire whirl is proposed, which consists in the interaction of the moving ions with the Earth’s magnetic field. It is shown that as far as the magnetic field around a fire whirl is concerned, the fire whirl is equivalent to a solenoid carrying a current Is, which is related to characteristics pertinent to the fire whirl. The vertical component of the magnetic field obtained from this model (Bzm) is compared with experimental results (Bze) acquired in fire whirls in a shaft model. The two sets of values (Bzm and Bze) are well correlated, with deviations which are reasonably acceptable. The results of the present work could be of value as a diagnostic tool in monitoring internal fire whirl and in studying various aspects of the whirl. +-----+ https://curiositystream.com/video/2967/herculaneum-scrolls-unraveling-history?playlist= Herculaneum Scrolls: Unravelling History >> Mount Vesuvius, Pompei 79 AD (Plague of Justinian?) 75 feet of volcanic ash over Hurculaneum I also watched : https://en.wikipedia.org/wiki/Eruption_of_Mount_Vesuvius_in_79 https://curiositystream.com/video/3202/escaping-rip-currents?playlist= ********** 19Nov2019 CRISPER https://curiositystream.com/video/1656/what-is-crispr Dolly - genetic copying of whole animal CRISPER - makes DNA changes easy to do arose from natural virus DNA destruction mechanisms? ?Agine?
