  Mount Nyiragongo - Encyclopedia, History, Geography and Biography
Hawaiian volcanic eruptions are also characterised by lavas with low silica content, but the Hawaiian volcanoes are broad, shallow-sloped shield volcanoes in contrast to the steep-sided cone of Nyiragongo, and the silica content is high enough to slow most flows to walking pace.
The 1977 eruption raised awareness of the unique dangers posed by Nyiragongo, and because of this it was designated a Decade Volcano, worthy of particular study, in 1991.
Lava lakes reformed in the crater in eruptions in 1982-1983 and 1994.

 Volcano Hazards - PDC
Many volcanoes around the world have been targeted for hazards research, with several of the most notorious volcanoes being designated Decade Volcanoes for concentrated hazards research, such as the Decade Volcano is Popocatepetl, which is within striking range of 30,000,000 people around it, including Mexico City.
Pyroclastic flows and surges are high-speed avalanches of hot ash, rock fragments, and gas that move down the sides of a volcano during explosive eruptions or when the steep edge of a dome breaks apart and collapses.
Volcanoes are susceptible to landslides because they are composed of layers of weak, fragmented, volcanic rocks that tower above the surrounding terrain.

Sheridan explains that "the real problem" in volcano forecasting "is to establish a base-line knowledge of what a volcano is like before it shows signs of danger." Then monitors can pick up on small surface deformations, gas emissions, faint underground rumbles, and other subtle signs of a volcano's awakening years before there's obvious action.
They noted that "many of the world's most dangerous volcanoes are still poorly understood," adding that "this lack of knowledge represents the most pressing problem in reducing volcanic risk in a global context." There's more to that risk than a rain of hot rocks or flaming rivers of lava.
Volcanoes to Watch Of the hundreds of volcanoes around the world, 15 active mountains have been designated "Decade Volcanoes" by the International Association of Volcanology and Chemistry of the Earth's Interior.

 Santa Maria: A Remote Sensing Perspective   (Site not responding. Last check: 2007-10-31)
The lengths of repose periods between eruptions vary from minutes to thousands of years, so many eruptions happen at volcanoes with no historic record of eruptions (13), and it is too expensive to put instruments on all potentially active volcanoes.
The basic description of the topography of a volcano is one of the most important parts of volcanic hazard evaluations, because most volcanic hazards are controlled by gravity and topography where volcanoes are topographic highs which threaten their lower lying surroundings through gravitational potential energy.
In nature it is impossible to find a single volcano which has all kinds of activity, and we think that at least two frequently active volcanoes (one effusive and one explosive) are needed to allow for the kinds of ground truth that are needed for comprehensive algorithm development and verification.
