A natural phenomenon that occurred in Indonesia once shook the world\nin 1883. The eruption of Mount Krakatoa in August 1883 killed more than\n36,000 lives and caused the Earth\u2019s overall temperature to drop by an\naverage of 0.6 degrees Celsius for several months afterwards.<\/p>\n
It is no wonder that the volcano in the Sunda Strait, which connects\nthe Java Sea and the Indian Ocean, possessed an explosive force\nequivalent to a 200-megaton bomb. The resurgence of Krakatoa in 1883\nremains one of the deadliest volcanic eruptions in modern history,\nsurpassed only by the eruption of Tambora in 1815, which killed 60,000\npeople.<\/p>\n
The impact was felt worldwide and even reached deep into the\nstratosphere, causing the Moon to appear blue at night. Quoting the\nofficial Natural History Museum website, the eruption released sulphur\ndioxide and other particles, such as ash, into the air. These particles\nfiltered the colours of sunlight reaching the Earth.<\/p>\n
Different colours have different wavelengths, with red being the\nlongest, violet being the shortest, and other colours falling in\nbetween, following the order of the rainbow. The volcanic particles were\nsmaller than one micron, approximately one hundred times smaller than\nthe thickness of a human hair. However, these particles were slightly\nwider than the wavelength of red light.<\/p>\n
When dispersed, these particles absorbed red light while allowing\nother colours to pass through. This produced dream-like vistas and\ntriggered various \u2018Blue Moon\u2019 phenomena. \u201cThe Krakatoa eruption is a\nstriking example of irresistible natural force,\u201d said Dr Martin Manglar,\nScientific Assistant at the Natural History Museum. \u201cIn the blink of an\neye, a volcanic eruption can change the shape of an entire planet in\nvarious ways, and the Blue Moon phenomenon may be the most beautiful and\nleast dangerous.\u201d<\/p>\n
Although the Krakatoa eruption more than a century ago affected the\nclimate and the world\u2019s colour palette for years, its impact has now\nsubsided. The reason the Moon appears blue occurs because other\nvolcanoes have erupted since then, sometimes releasing particles of the\nsame size as those produced by Krakatoa. Additionally, some forest fire\nevents produce a similar combination of sulphur dioxide and ash,\ncreating a similar effect. Depending on the intensity of the cause,\nthese particles can be carried across countries, creating Blue Moon\nphenomena for people in other parts of the world.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/krakatoa-erupts-earth-changes-completely-36-000-killed-instantly-1788681274", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
