	Vic Camp - the Nevado del Ruiz eruption
		Nevado del Ruiz is the northernmost of several Colombian stratovolcanoes in the Andes Volcanic Chain of western South America.
		With a summit elevation of 5,389 m (over 17,500 ft), Nevado del Ruiz is the highest of the Colombian volcanoes.
		Nevado del Ruiz had served up a steady menu of minor earthquakes and steam eruptions for 51 weeks prior to the November 13 eruption.

	Nevado del Ruiz - Peakware World Mountain Encyclcopedia
		Nevado del Ruiz is an active volcano, located in a compact cluster of volcanic mountains near the center of Colombia.
		Nevado del Ruiz is not only the highest mountain in the region, but is one of the easiest to ascend, straight up the snowy west slope from a parking lot at the base of the mountain.
		Nevado del Ruiz is the northernmost peak in this north-south alignment of peaks, while Nevado del Tolima is the farthest south.

	Ruiz, Colombia
		Ruiz is the northern-most historically active volcano in South America (4.9N, 75.3W).
		Because of the high elevation of the summit (17,453 feet, 5,321 m), the volcano is capped by a large volume of snow and ice.
		This eruption of Ruiz was the second mostly deadly of the century (Mount Pelee in Martinique was first, killing 29,000 people in its 1902 eruption).

		Nevado Ruiz is the most massive of the volcanoes and it looks like the upper part of Kilimanjaro.
		Nevado Ruiz is also one of the deadliest mountains in the world, as a single eruption killed over 23,000 people on November 13, 1985.
		Nevado Tolima and Santo Isabel are the only peaks that require an ice axe and crampons, though Ruiz may require one in the future if the glacier reforms after being melted away by the eruption.

	Nevado Del Ruiz and Nevada Del Tolima: The Volcanoes of Central Colombia
		Earlier eruptions of Nevado del Ruiz occurred in 1595 and again in 1845 and it is known the eruptions melted snow and ice and produced mudflows that travelled many kilometres from the volcano.
		This eruption of Nevado del Ruiz was the second mostly deadly of the twentieth century (Mount Pelee in Martinique was first, killing 29,000 people in its 1902 eruption.) It is believed that one tenth of the world's population live within the danger zone of volcanoes.
		The volcanoes of Nevado del Ruiz and Nevada del Tolima in Parque Nacional Los Nevados in central Colombia are beautiful mountains and should not be dismissed by climbers visiting South America.

	No Apparent Danger by Victoria Bruce
		In 1985 Calvache was part of a group of Colombia's brightest young scientists that had been studying activity at Nevado del Ruiz, a volcano three hundred miles north of Galeras.
		When Nevado del Ruiz erupted suddenly in November 1985, it wiped the city of Armero off the face of the earth and killed more than twenty-three thousand people -- one of the worst natural disasters of the twentieth century.
		In the aftermath of Nevado del Ruiz, volcanologists from all over the world came to Galeras -- some to ensure that such horrors would never be repeated, some to conduct cutting-edge research, and some for personal gain.

	This Day in History 1985: The eruption of Nevado del Ruiz (Site not responding. Last check: )
		Nevado del Ruiz, the highest active volcano in the Andes Mountains of Colombia, suffers a mild eruption that generates a series of lava flows and surges over the volcano's broad ice-covered summit.
		Flowing mixtures of water, ice, pumice, and other rock debris poured off the summit and sides of the volcano, forming "lahars" that flooded into the river valleys surrounding Ruiz.
		The volcano first began showing signs of an imminent eruption a full year before, and most of the river valley's residents would have survived had they have moved to higher ground.

	Global Volcanism Program \| Nevado del Ruiz \| Summary
		Nevado del Ruiz is a broad, glacier-covered volcano in central Colombia that covers >200 sq km.
		The modern cone consists of a broad cluster of lava domes built within the summit caldera of an older Ruiz volcano.
		Melting of its summit icecap during historical eruptions, which date back to the 16th century, has resulted in devastating lahars, including one in 1985 that was South America's deadliest eruption.
