Mount Tambora, or Tomboro, is an active stratovolcano in West Nusa Tenggara, Indonesia. Located on Sumbawa in the Lesser Sunda Islands, volcanism is the result of subduction zones. The 1815 eruption was the largest in recorded history, erupting up to 150 cubic kilometers of volcanic material, making it a VEI-7 on the Volcanic explosivity index. This caused the summer of 1816 to become known as the "Year Without a Summer" due to global cooling from the eruption.
In April 1815, Mount Tambora, a volcano on the island of Sumbawa in present-day Indonesia (then part of the Dutch East Indies), erupted in what is now considered the most powerful volcanic eruption in recorded human history. This eruption, with a volcanic explosivity index (VEI) of 7, ejected 37–45 km (8.9–10.8 cubic miles) of dense-rock equivalent (DRE) material into the atmosphere, and was the most recent confirmed VEI-7 eruption.
Although the Mount Tambora eruption reached a violent climax on 10 April 1815, increased steaming and small phreatic eruptions occurred during the next six months to three years. The ash from the eruption column dispersed around the world and lowered global temperatures in an event sometimes known as the Year Without a Summer in 1816. This brief period of significant climate change triggered extreme weather and harvest failures in many areas around the world. Several climate forcings coincided and interacted in a systematic manner that has not been observed after any other large volcanic eruption since the early Stone Age.
The 1810s (pronounced "eighteen-tens") was a decade of the Gregorian calendar that began on January 1, 1810, and ended on December 31, 1819.
The decade was opened with a very hostile political climate around the world. Napoleon was invading France's neighbours in efforts to build a French Empire, causing a chain of global-scaled conflicts known as the Napoleonic Wars. Here, France's Napoleonic empire saw its rise and fall through events such as Napoleon's attempts to conquer Russia, the War of 1812 (spillover to America), and the Battle of Waterloo (Napoleon's ultimate defeat). Imperialism began to encroach towards African and Asian territories through trade, as the United States saw mass-scaled migration that headed westward towards the American frontier (mostly through the opening of the Oregon Trail.)
Sail Indonesia is a series of sailing and other events for yachts conducted each year in Indonesia. The events are organised by Yayasan Cinta Bahari Indonesia (YCBI) and supported by the high-profile tourist destinations to international yachtsmen and women with a view to expanding the tourism potential and raising awareness of the region as well as introducing visitors to natural and cultural features of the Indonesian archipelago that they might otherwise not visit.
The sailing event started in 2001, and has been held annually ever since. The latest event is being held in the name as 2018 Sail Moyo Tambora centering around Moyo Island and Mount Tambora of West Nusa Tenggara province.
Tambora is the poorly attested non-Austronesian (Papuan) language of the Tambora culture of central Sumbawa, in what is now Indonesia, that was made extinct by the 1815 eruption of Mount Tambora. It was the westernmost known Papuan language and was relatively unusual among such languages in being the language of a maritime trading state, though contemporary Papuan trading states were also found off Halmahera in Ternate and Tidore.
