The last eruption of this stratovolcano occurred in March 1944. A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and effusive eruptions, although some have collapsed craters called calderas.
Where did tobacco originate from? We already know that processed tobacco comes from the tobacco plant, most commonly Nicotiana tabacum. Plants from the Nicotiana family originated from both North and South America, Australia, Africa and the South Pacific. However, the tobacco that is most commonly grown as a cash crop today originated in the Americas where it had long been cultivated and used by the native people. Christopher Columbus was the first European to be introduced to the plant on his first voyage to the New World.
