After nearly 200 years of rest, Mount Tambora is rumbling again and spewing ash. The last eruption of Mount Tambora was in 1815 and at the time was the largest eruption in the world since 180 AD. The massive amount of volcanic ash kicked into the stratosphere (around 160 cubic kilometers of ejecta were released) cooled Earth's temperature by over a degree Fahrenheit and caused "The year without a summer". In comparison, the 1980 eruption of Mount Saint Helens released around 1 cubic kilometer of ejecta.
