Task 4

Kelimutu: Astounding Tri-Coloured Crater Lakes

Source:wisoto.com

7My Unforgettable Moment

Kelimutu is a volcano, close to thesmalltownofMoniabout50kmtotheeastofEndeincentralFloresIsland.Thevolcano contains three striking summit crater lakesof varying colours.They are located on the same volcanic peak yet each of the three crater lakes is a markedly different colour. It is the only place onearth where this amazing colour variation takes place.

The three lakes all have differentnames and local people have for centuries believed that the lakes are the spiritual resting place of their ancestors. It is said the lakes change colour according to the mood of the spirit.

TheLakeofOldPeople (TiwuAtaMbupu) at the western point of the volcano is typically blue. Lying apartfromtheothertwocrater,thisiswhereitis said the spirits of the old who have led righteous lives go to rest.

The two other lakes share a crater wall. The Lake of Young Men andMaidens (TiwuNuwaMuriKooFai) ischaracteristically green. The third, theEnchantedLake(TiwuAtaPolo)canoftenbe blood red but sometimes it appears an olive colour.This is the one where the bad peoplego,young,old,maleorfemale.

Kelimutu itselfmeansBoilingLakeand often visitors can see wreathes of steam rise from the surface of the lakes.Despitethefactthevolcanoandlakesare

littleknownoutsideAsia,manyconsiderKelimutu to be one of the seven wonders of nature. It is hard to disagree.

Adapted from:www.kuriositas.com; www.indonesia.travel; en.wikipedia.org

Why Do Kelimutu Lakes HaveColours?

Crater lakes on their own are amazingnaturalwonders,butthecraterlakes of Kelimutu volcano in Indonesia are even more striking. They are each a different colour despite being at thecrest of the same volcano.The three lakes periodically vary in colour independent of each other.

Geologists believe the three lakes change colour as a result of chemical reactions between the minerals in the lakes and volcanic gas.Although no extensive scientific surveyhas everbeenundertaken below the surface of the lakes it is assumed that the colour deviations ofKelimutuLakesareduetounderwaterfumaroles. These are openings in the planet’s surface which let out gas andsteam–sulfurdioxide,hydrogenchlorideand sulfide as well as carbon dioxide.This creates an upwelling which drives denser nutrient-rich and so coloured water upwards to the surface, drivingthatwhichhadbeenontopdownwards,so changing its appearance.

Merapi Volcano

10 Forward English for Senior High School Students Grade X

Source: totallycoolpix.comMerapi,a steepstratovolcanonorth

of Central Java’s capital Yogyakarta,is Indonesia’s most active volcano. Iterupts on average every 5-10 years andis feared for its deadly pyroclastic flows - avalanches of hot rocks and gas that are generated when parts of new lava domes constructed during eruptions in the summit crater collapse and slide down themountain’ssteepflanks.

The name “Merapi” from old Javanese languagemeans“theonemakingfire”isa popular name for volcanoes: another volcano with the same name Merapi is in theIjenMassifinEastJavaandsimilarlycalled volcano “Marapi” lies on Sumatra Island.

Merapi dominates the landscape immediately north of the city of Yogyakarta in one of the world’s mostdensely populated areas. Merapi is the youngest and southernmost of a volcanic chain extending NNW to Ungaran

volcano. The steep-sided modern Merapi edifice, its upper part unvegetateddue to frequent eruptive activity, wasconstructed to the SW of an arcuate scarp cutting the eroded older Batulawang volcano. Pyroclastic flows and laharsaccompanying growth and collapse of the steep-sided active summit lava dome have devastated cultivated lands on the volcano’swestern-to-southernflanksandcaused many fatalities during historical time. Since 1953, activity has beencharacterized by extrusion of lava into the summit crater, with periodic lavadomecollapseandnuéeardente(Frenchfor “burning cloud”) formation. Summit lava dome growth has continued since the 1969 gas explosion. It is monitored from theMerapiVolcanoObservatory(MVO)in Yogyakarta.

Solo River, or Bengawan Solo asit is called locally (Bengawan is an oldJavaneseword for river), is the longestriver on the Indonesian island of Java.Solo River is approximately 540km inlength.

TheSoloRiver(orBengawanSolo)has its source by the volcano of Mount Lawu, on the border between CentralJava and East Java. It passes throughthemajorcityofSurakarta(calledSoloby the local inhabitants). An important early tributary to the Solo river is the DengkengRiver,whichhasitssourceinMount Merapi. After passing through Solo, the riverflowsnorthwardaroundMount Lawu, and then turn eastwardintoEastJavaintheNgawiregency.

After Ngawi the river turnsnorthwardagain,formingtheboundarybetween Blora Regency of Central Java and Bojonegoro regency of East Java.From the town of Cepu in Blora, theriver turns eastward and passes through Bojonegoro regency’s capital city.From

there,itcontinueseastwardthroughtheLamonganandGresikregencies.Thelastpartoftheriver’sbasin(roughlystartingfrom Bojonegoro regency) is mostly flat land.

Bengawan Solo’s delta is locatednear the town of Sedayu in Gresik regency. The present delta is redirected by a human made canal. The original deltaflowedintotheMaduraStrait,butin1890a12kmcanalwasmadebytheDutchEastIndiesauthority toredirectthe Solo River into Java Sea. This is done to prevent sedimentation of mud from filling the Madura Strait and therebypreventing sea access to the important port city of Surabaya.
