Under an 1815 Volcano Eruption, Remains of a 'Lost Kingdom'

One of history's most violent volcanic eruptions blasted the island of Sumbawa in the East Indies in 1815. The sulfurous gases and fiery ashes from Mount Tambora cast a pall over the entire world, causing the global cooling of 1816, known as the "year without a summer." It left 117,000 people dead. A team of American and Indonesian scientists has now found remains of what it says is the "lost kingdom of Tambora."
