Gunung Tambora is located on the island of Sumbawa in Indonesia's Nusantara Barat Province (NTB). In 1815 it was the site of the most powerful explosion in modern history - an explosion that was heard as far away as Batavia. The mountain was reduced from 4200m to 2800m. It is estimated that 36 cubic kilometers of the mountain was reduced to dust which then swirled around the globe for the next few years, resulting in a,'year without summer' in Europe and a period of spectacular sunsets some of which can be seen in the paintings of English landscape artist, John Constable. The explosion, which was far, far, bigger than that of Krakatoa in 1883, devastated the peninsula on which Tambora is located, killing many thousands of people outright and rendering much of the country inhabitable for years to come. The resulting famine led to thousands of more deaths.
It is possible to climb Tambora but be warned - it is not a stroll in the park. You have to be physically very fit and be ready for some discomfort and danger. Very few Indonesians, and far fewer foreigners ever make it to this out of way place. For example in the first six months of 2009 only three groups climbed the mountain - a group of nine Indonesians, a Frenchman and myself, one of just two Australians to make the ascent since 2004 when records began to be kept by K-PATA - Kelompok Pencinta Alam Tambora (The Tambora Nature Lovers Group) whose appointed officer, Shaiful keeps the records
