The Nevado del Ruiz (Spanish pronunciation: [neβaðo ðel ˈrwis]), also known as La Mesa de Herveo (English: Mesa of Herveo, the name of the nearby town) is a volcano on the border of the departments of Caldas and Tolima in Colombia, about 129 kilometers (80 mi) west of the capital city Bogotá. It is a stratovolcano composed of many layers of lava alternating with hardened volcanic ash and other pyroclastic rocks. Volcanic activity at Nevado del Ruiz began about two million years ago, since the Early Pleistocene or Late Pliocene, with three major eruptive periods. The current volcanic cone formed during the present eruptive period, which began 150,000 years ago. The volcano usually generates Vulcanian to Plinian eruptions, which produce swift-moving currents of hot gas and rock called pyroclastic flows. These eruptions often cause massive lahars (mud and debris flows), which pose a threat to human life and the environment. The impact of such an eruption is increased as the hot gas and lava melt the mountain's snowcap, adding large quantities of water to the flow. On November 13, 1985, a small eruption produced an enormous lahar that buried and destroyed the town of Armero in Tolima, causing an estimated 25,000 deaths. This event later became known as the Armero tragedy—the deadliest lahar in recorded history. Similar but less deadly incidents occurred in 1595 and 1845, consisting of a small explosive eruption followed by a large lahar. The volcano is part of Los Nevados National Natural Park, which also contains several other volcanoes. The summit of Nevado del Ruiz is covered by large glaciers. The volcano continues to pose a threat to the nearby towns and villages, and it is estimated that up to 500,000 people could be at risk from lahars from future eruptions. Today, the Nevado del Ruiz volcano is constantly monitored by the Volcanic and Seismic Observatory of Manizales.

The Great Famine of 1315–1317 (occasionally dated 1315–1322) was the first of a series of large-scale crises that struck Europe early in the 14th century. Most of Europe (extending east to Russia and south to Italy) was affected. The famine caused many deaths over an extended number of years and marked a clear end to the period of growth and prosperity from the 11th to the 13th centuries.The Great Famine started with bad weather in spring 1315. Crop failures lasted through 1316 until the summer harvest in 1317, and Europe did not fully recover until 1322. Crop failures were not the only problem; cattle disease caused sheep and cattle numbers to fall as much as 80 percent. The period was marked by extreme levels of crime, disease, mass death, and even cannibalism and infanticide. The crisis had consequences for the Church, state, European society, and for future calamities to follow in the 14th century.
