Mount Meru is an active volcano located 70 kilometres (44 miles) west of Mount Kilimanjaro. At a height of 4,566 metres (14,980 ft), it is still visible from Mt Kilimanjaro on a clear day. Much of its bulk was lost about 8,000 years ago due to an eastward volcanic blast, similar to the 1980 eruption of Mount St. Helens in the U.S. state of Washington. Mount Meru most recently had a minor eruption about a century ago. The several small cones and craters seen in the vicinity probably reflect numerous episodes of volcanic activity.
Mount Meru is the topographic centerpiece of Arusha National Park. Its fertile slopes rise above the surrounding savanna and support a forest that hosts diverse wildlife, including nearly 400 species of birds, and also monkeys and leopards.At the summit, one can find a two metre high flag of Tanzania
