The mountain
Gunung Merapi or Mount Merapi (2,914m - 9,500 ft) is an active stratovolcano located on the border between Central Java and Yogyakarta, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. It is located approximately 28 kilometres (17 mi) north of Yogyakarta city which has a population of 2.4 million, and thousands of people live on the flanks of the volcano, with villages as high as 1,700 metres (5,600 ft) above sea level.
Smoke can often be seen emerging from the mountaintop, and several eruptions have caused fatalities. Pyroclastic flow from a large explosion killed 27 people on 22 November 1994, mostly in the town of Muntilan, west of the volcano.Another large eruption occurred in 2006, shortly before the Yogyakarta earthquake. In light of the hazards that Merapi poses to populated areas, it has been designated as one of the Decade Volcanoes....
Friedrich Franz Wilhelm Junghuhn was a German-Dutch botanist and geologist, who studied medicine in Halle and in Berlin from 1827 to 1831, meanwhile publishing (1830) a seminal paper on mushrooms in Limnaea. Junghuhn settled on Java, where he made an extensive study of the land and its people. He discovered the Kawah Putih crater lake south of Bandung in 1837.
He published extensively on his many often highly adventurous expeditions and his scientific analyses. Among his works is an important description and natural history in many volumes of the volcanoes of Java, Bijdragen tot de geschiedenis der vulkanen in den Indischen Archipel (1843).
He completed Die Topographischen und Naturwissenschaftlichen Reisen durch Java (Topographic and Scientific Journeys in Java) in 1845 and a first anthropological and topographical study of Sumatra, Die Bättalander auf Sumatra (Batak lands of Sumatra). in 1847.
In 1849, ill health forced his return to the Netherlands. While in the Netherlands, Junghuhn began work on a four volume treatise published in Dutch and translated into German between 1850 and 1854: Java, deszelfs gedaante, bekleeding en inwendige struktuur. Junghuhn was an avid humanist and socialist. In the Netherlands he published anonymously his free-thinking manifesto Licht- en Schaduwbeelden uit de Binnenlanden van Java (Images of Light and Shadow from Java's interior) between 1853 and 1855. The work was controversial, advocating socialism in the colonies and fiercely criticizing Christian and Islamic proselytization of the Javanese people. Junghuhn instead wrote of his preference for a form of Pandeism (pantheistic deism), contending that God was in everything, but could only be determined through reason. The work was banned in Austria and parts of Germany for its "denigrations and vilifications of Christianity", but was a strong seller in the Netherlands where it was first published pseudonymously. It was also popular in colonial Indonesia, despite opposition from the Dutch Christian Church there.
Recovered from his ills, Junghuhn returned to Java in 1855. He remained on Java until his death from liver disease in 1864. On his deathbed in his house near Lembang on the slopes of the volcano Tangkuban Perahu just north of Bandung, Java, it is said that Junghuhn asked the doctor to open the windows, in order to say goodbye to the mountains that he loved.
In Lembang there is a small monument to his memory in a grassy square named after him planted with some of his favorite trees among which the Cinchona. A minor item of trivia playing into polemical discussions of Junghuhn is his surname, literally translated as "young chicken".
The plants Cyathea junghuhniana and Nepenthes junghuhnii are named after Franz Junghuhn.
