The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Cerro Negro, Central America's youngest volcano was born in April 1850 and is one of the region's most active volcanoes. It has been producing frequent strombolian eruptions, occasional lava fountains and lava flows, and powerful explosive eruptions every few decades.
Cerro Negro lies in a sparsely populated area and its eruptions have not caused significant damage nearby, but ash fall from its sometimes strong explosions have damaged farmland and houses in the populated areas of the Nicaraguan depression.
An unusual number of earthquakes have been noted near the volcano recently, prompting authorities to warn tourists and locals not to climb the volcano, local press reports. ...more
Whether the earthquakes are precursors of a possible new eruption is uncertain, but Cerro Negro is one of the country's most active volcanoes with at least 23 recorded historical eruptions, last in 1992, 1995 and 1999. Cerro Negro's eruptions are often violent with tall lava fountains and tall ash plumes, and often preceded by earthquakes. [less]
