On April 12, 1815, exactly 203 years ago, the Tambora volcano on the remote island of Sumbawa, West Nusa Tenggara -NTB erupted so violently. Consequently, thick ash clouds were brought around the world. As is known, if the mega-eruption of Mt. Toba is believed to have plunged the earth into volcanic winter for 6 to 10 years, and the explosion of Mt. Krakatau in 1883 produced the loudest sound ever heard in the world in modern history, Mt. Tambora volcano eruption also created a global catastrophe at that time. One year later in 1816, it erupted again. In Europe and America, it was remembered as the "Year Without Summer", which resulted in the worst season of the nineteenth century. Its mighty eruption in April 1815 left an impressive 7-kilometer area with a 6.2 km caldera containing two colored lakes with a depth of 800 meters. This caldera is also considered the largest caldera in Indonesia. Currently, scientists recognize the Tambora eruption as the most powerful in the history of volcanic eruptions. To commemorate this dramatic event as well as commemorate the anniversary of Dompu Regency, Sumbawa, Wonderful Tambora Festival 2018 –FPT 2018 will be held again on 9 - 11 April 2018.
