1883 eruption of Krakatoa
summarry
The 1883 eruption of Krakatoain the Dutch East
Indies(now in Indonesia) began on August 26,
1883 (with origins as early as May of that
year) and culminated with several destructive
eruptions of the remaining caldera.

Timelene Of Eruption
Krakatoa was dormant until May 20, 1883, whenit erupted catastrophically. By August 11, threevents were regularly erupting on the volcano
The August 26 eruptions occurred at 5:30 am,6:42 am, 8:20 am and 10:02 am local time
Small eruptions, mostly of mud, continued intoOctober 1883

MORE DETAILED TIMELINE OF THE
EVENT By 25 August, eruptions further intensified. At about 13:00 (local time) on 26 August, the volcano went into its paroxysmal
phase. By 14:00 observers could see a black cloud of ash 27 km (17 mi) high. At this point, the eruption was virtually
continuous and explosions could be heard every ten minutes or so. Ships within 20 km (12 mi) of the volcano reported
heavy ash fall, with pieces of hot pumice up to 10 cm (3.9 in) in diameter landing on their decks. A small tsunamihit the
shores of Javaand Sumatra, some 40 km (25 mi) away, between the time of 18:00 and 19:00 hours.
On 27 August four enormous explosions took place at 05:30, 06:44, 10:02, and 10:41 local time. At 5:30 A.M, the first
explosion was at Perboewatanvolcano, triggering a tsunami heading straight to Telock Botong. At 6:44 A.M, Krakatoa
exploded again on Dananvolcano, with the resulting tsunami stretching eastward and westward. At 10:02 A.M, is the
biggest explosion, the 3rd explosion was so violent that it was heard 3,110 km (1,930 mi) away in Perth, Western Australia,and the Indian Oceanisland of Rodriguesnear Mauritius(4,800 km (3,000 mi) away), where they were thought to be
cannon fire from a nearby ship.[2][3]:22Each explosion was accompanied by large tsunamis, which are believed to have been
over 30 meters (100 ft) high in places. A large area of the Sunda Straitand a number of places on the Sumatran coast were
affected by pyroclastic flowsfrom the volcano. The energy released from the explosion has been estimated to be equal to
about 200 megatons of TNT,[4]roughly four times as powerful as the Tsar Bomba(the most powerful thermonuclear
weapon ever detonated). At 10:41 A.M, a landslide tore off half of Rakatavolcano causing the final explosion.
Final explosive eruption
The pressure wave generated by the colossal fourth and final explosion radiated out from Krakatoa at 1,086 km/h(675 mph).It was so powerful that it ruptured the eardrums of sailors on ships in the Sunda Strait,and caused a spike of
more than 2 inches of mercury(ca 85 hPa) in pressure gauges attached to gasometersin the Batavia gasworks, sending
them off the scale.The pressure wave radiated across the globe and was recorded on barographsall over the world, which
continued to register it up to 5 days after the explosion. Barographic recordings show that the shock-wave from the final
explosion reverberated around the globe 7 times in total. Ash was propelled to an estimated height of 80 km (50 mi).
The eruptions diminished rapidly after that point, and by the morning of 28 August, Krakatoa was silent. Small eruptions,
mostly of mud, continued into October 1883.

Effect of Krakatoa EruptionGeographic effects
Evolution of the islands around KrakatoaIn the aftermath of the eruption, it was found that the island of Krakatoa had almost entirelydisappeared, except for the southern third. The Rakata cone was cut-off along a vertical cliff,leaving behind a 250-metre (820 ft)deep caldera. Of the northern two-thirds of the island, only arocky islet named Bootsmansrots ('Bosun's Rock'), a fragment of Danan, was left; Poolsche Hoedhad totally disappeared,it also make new island called Anak Krakatoa.
As a result of the huge amount of material deposited by the volcano, the surrounding ocean floorwas drastically altered. It is estimated that as much as 1821 km3(4.35.0 cu mi) of ignimbrite
was deposited over an area of 1,100,000 km2(420,000 sq mi), largely filling the30
40 m (98130 ft) deep basin around the mountain. The land masses of Verlatenand Langislands were
increased, as was the western part of the remnant of Rakata. Much of this gained materialquickly eroded away, but volcanic ash continues to be a significant part of the geologicalcomposition of these islands.
Two nearby sandbanks(called Steersand Calmeyerafter the two naval officers who investigatedthem) were built up into islands by ashfall, but the sea later washed them away. Seawater on hotvolcanic deposits on Steers and Calmeyer had caused steam to rise, which some mistook for acontinued eruption.

Tsunamis and distant effects
Ships as far away as South Africarocked as tsunamis hit them, and the bodies ofvictims were found floating in the ocean for months after the event. The tsunamiswhich accompanied the eruption are believed to have been caused by giganticpyroclastic flows entering the sea; each of the four great explosions wasaccompanied by massive pyroclastic flows resulting from the gravitational collapseof the eruption columns. This caused several cubic kilometers of material toenterthe sea, displacing an equally huge volume of seawater. The town of Merakwasdestroyed by a tsunami 46 m (151 ft) high. Some of the pyroclastic flows reachedthe Sumatran coast as much as 40 km (25 mi) away, having apparently movedacross the water on a cushion of superheated steam. There are also indications ofsubmarine pyroclastic flows reaching 15 km (9.3 mi) from the volcano.
Smaller waves were recorded on tidal gauges as far away as the EnglishChannel.These occurred too soon to be remnants of the initial tsunamis, and mayhave been caused by concussive air waves from the eruption. These air wavescircled the globe several times and were still detectable on barographs five dayslater.

Global climate
In the year following the eruption, average global temperatures fell by as much as 1.2 C (2.2 F).[citation needed]Weather patterns continued to be chaotic for years, and temperatures did not returnto normal until 1888.[Theeruption injected an unusually large amount of sulfur dioxide(SO2) gas high into the stratosphere, which wassubsequently transported by high-level winds all over the planet. This led to a global increase in sulfuric acid(H2SO4) concentration in high-level cirrus clouds. The resulting increase in cloud reflectivity(or albedo) wouldreflect more incoming light fromthe sun than usual, and cool the entire planet until the suspended sulfurfell tothe ground as acid precipitation.
Global optical effects
The eruption darkened the sky worldwide for years afterward, and produced spectacular sunsets throughout theworld for many months. British artist William Ashcroftmade thousands of colour sketches of the red sunsets half-way around the world from Krakatoa in the years after the eruption. The ash caused "such vivid red sunsets thatfire engines were called out inNew York, Poughkeepsie, and New Haven to quench the apparent conflagration."This eruption also produced a Bishop's Ringaround the sun by day, and a volcanic purple light at twilight.
In 2004, an astronomer proposed the idea that the blood-red sky shown in Edvard Munch's famous 1893 paintingThe Screamis also an accurate depiction of the sky over Norwayafter the eruption.[14]
Weather watchers of the time tracked and mapped the effects on the sky. They labeled the phenomenon the"equatorial smoke stream".This was the first identification of what is known today as thejet stream.[16]
For several years following the eruption it was reported that the moon appeared to be blue and sometimesgreen. Blue moonsresulted because some of the ash-clouds were filled with particles about 1 micron widetheright size to strongly scatter red light, while allowing other colors to pass. White moonbeams shining through thecloudsemerged blue, and sometimes green. People also saw lavender suns and, for the first time, noctilucentclouds.

Possible causes
The established theories - based on the findings of contemporary investigators - assume that part ofthe island subsided before the first explosions on the morning of 27 August. This forced thevolcano's vents below sea level causing :
massive flooding which created a series of phreatic explosions(interaction of ground water andmagma).
seawater to cool the magmaenough for it to crust over and produce a "pressure cooker" effectrelieved only when explosive pressures were reached.
However there is geological evidence which does not support the assumption that only subsidencebefore the explosion was the cause. For instance, the pumice and ignimbrite deposits are not of akind consistent with a magma-seawater interaction. These findings have led to other hypotheses:
a massive underwater land slump or partial subsidence suddenly exposed the high-pressurizedmagma chamber to seawater.
the final explosions may have been caused by magma mixingcaused by a sudden infusion of hotbasaltic magma into the cooler and lighter magma in the chamber below the volcano. This wouldhave resulted in a rapid and unsustainable increase in pressure, leading to a cataclysmicexplosion. Evidence for this theory is the existence of pumice consisting of light and dark
material, the dark material being of much hotter origin. However, such material reportedly is lessthan 5% of the content of the Krakatoa ignimbriteand some investigators have rejected this as aprime cause of the 27 August explosions.
