Peru Geography Profile

earthquakes, tsunamis, flooding, landslides, mild volcanic activity

volcanism: volcanic activity in the Andes Mountains; Ubinas (5,672 m), which last erupted in 2009, is the country's most active volcano; other historically active volcanoes include El Misti, Huaynaputina, Sabancaya, and Yucamane; see note 2 under "Geography - note"

note 1: shares control of Lago Titicaca, world's highest navigable lake, with Bolivia; a remote slope of Nevado Mismi, a 5,316 m peak, is the ultimate source of the Amazon River

note 2: Peru is one of the countries along the Ring of Fire, a belt of active volcanoes and earthquake epicenters bordering the Pacific Ocean; up to 90% of the world's earthquakes and some 75% of the world's volcanoes occur within the Ring of Fire

note 3: on 19 February 1600, Mount Huaynaputina in the southern Peruvian Andes erupted in the largest volcanic explosion in South America in historical times; intermittent eruptions lasted until 5 March 1600 and pumped an estimated 16 to 32 million metric tons of particulates into the atmosphere reducing the amount of sunlight reaching the earth's surface and affecting weather worldwide; over the next two and a half years, millions died around the globe in famines from bitterly cold winters, cool summers, and the loss of crops and animals

note 4: the southern regions of Peru and the extreme northwestern part of Bolivia are considered to be the place of origin for the common potato
