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.

Saint Marcellus's flood or Grote Mandrenke (Low Saxon: /ɣroːtə mandrɛŋkə/; Danish: Den Store Manddrukning, 'Great Drowning of Men') was an intense extratropical cyclone, coinciding with a new moon, which swept across the British Isles, the Netherlands, northern Germany, and Denmark (including Schleswig/Southern Jutland) around 16 January 1362 (OS), causing at least 25,000 deaths. The storm tide is also called the 'Second St. Marcellus flood' because it peaked 16 January, the feast day of St. Marcellus. A previous 'First St. Marcellus flood' drowned 36,000 people along the coasts of West Friesland and Groningen on 16 January 1219. An immense storm tide of the North Sea swept far inland from England and the Netherlands to Denmark and the German coast, breaking up islands, making parts of the mainland into islands, and wiping out entire towns and districts such as: Rungholt, said to have been located on the island of Strand in North Frisia; Ravenser Odd in East Yorkshire; and, the harbour of Dunwich.This storm tide, along with others of like size in the 13th century and 14th century, played a part in the formation of the Zuiderzee, and was characteristic of the unsettled and changeable weather in northern Europe at the beginning of the Little Ice Age.
