Problems
Although studies at many volcanoes have led to a clear reduction in the risk faced by nearby settlements, eruptions at some of the Decade Volcanoes have demonstrated the difficulties faced by the programme. Eruptions at Mount Unzen which began shortly before it was designated a Decade Volcano were heavily monitored, but despite this, a large pyroclastic flow killed 43 people, including three volcanologists.
Later, a Decade Volcano conference in the city of Pasto, Colombia in 1993 ended in disaster when several of the scientists present mounted an impromptu expedition to the crater of Galeras. An eruption occurred unexpectedly while they were at the summit, which resulted in the deaths of six scientists and three tourists.
Another problem faced by the programme has been civil unrest in the vicinity of several volcanoes. The Civil War in Guatemala affected studies of Volcán Santa María until a ceasefire was called in 1996, while ongoing civil war in the Democratic Republic of the Congo has hampered studies of Nyiragongo volcano. More generally, scarce resources for volcano studies have led to programmes competing for limited funding.

Famous quotes containing the word problems:
“If we parents accept that problems are an essential part of life’s challenges, rather than reacting to every problem as if something has gone wrong with universe that’s supposed to be perfect, we can demonstrate serenity and confidence in problem solving for our kids....By telling them that we know they have a problem and we know they can solve it, we can pass on a realistic attitude as well as empower our children with self-confidence and a sense of their own worth.”
—Barbara Coloroso (20th century)
“I am always glad to think that my education was, for the most part, informal, and had not the slightest reference to a future business career. It left me free and untrammeled to approach my business problems without the limiting influence of specific training.”
—Alice Foote MacDougall (1867–1945)
“One of the annoying things about believing in free will and individual responsibility is the difficulty of finding somebody to blame your problems on. And when you do find somebody, it’s remarkable how often his picture turns up on your driver’s license.”
—P.J. (Patrick Jake)
