Mount Tambora
Tambora is the poorly attested non-Austronesian (Papuan) language of the Tambora culture of central Sumbawa, in what is now Indonesia, that was wiped out 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.
