(Video: Ultimate Volcano)
The Nevado del Huila volcano in Colombia hadn't erupted in 500 years. In other words, we're talking about back when the country was colonized by the Spanish. However, as with everything else in this world, nature is no longer something to be counted on (at least not in a good way). Thus, on Tuesday April 17, 2007, the Nevado del Huila volcano erupted once more, forcing 10,000 people to be on alert.
The country had already evacuated 3,500 from the area by the next day. And now, of course, Nevado del Huila has been added to the ever growing list of worrisome volcanoes.
Volcanoes are seismic. If this activity continues, we may see more and more long-dormant volcanoes suddenly come to life.
Here are a list of ten to worry about in the coming years (no order).
In other words, the world has to worry about Nevado del Huila.
Many scientists believe that a large scale eruption is imminent. Unfortunately, that means that the city of Yogyakarta could be in big trouble.
Further, Merapi is one of 16 volcanos designated by the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) as a Decade Volcano. In other words, it is considered to be a volcano that must be watched in light of its history and closeness to populated areas.
To this day, they still are.
If Mount Baker were to erupt, the greatest worry would be the lahars. In other words, if the volcano were to erupt, it would likely melt snow and ice that would serve to help the flow of sediment and such. Further, collapses of landscapes could serve to foster these landslides.
So watch out all of you Washington residents.
The largest debris avalanche on record from Rainier traveled a course of over 60 miles to Puget Sound. The last time Mount Rainier erupted was 2,200 years ago. Unfortunately, if that eruption were to repeat itself, the damage would be devastating. Mount Ranier is also a Decade Volcano.
Mauna Loa is located in Hawaii and is an active shield volcano. Its name means 'long mountain' in Hawaiian, which is appropriate considering it is the Earth's largest volcano. Guesses estimate that the volcano emerged from the sea around 400,000 years ago and has been erupting for about 700,000 years. Its magma comes from the same part of the Earth's mantle below the island that is responsible for the emergence of the Hawaiian islands.
Mauna Loa has not erupted since 1984. Further, it is believed that the volcano will eventually become extinct. However, if it were to erupt on a large scale the results could be absolutely devastating. This, of course, prompted its inclusion on the Decade Volcanoes list.
The good thing is that it is dormant. In fact, it last erupted in 1909. However, as we have seen, a volcano can go from dormant to active very quickly, and Teida's proximity to population centers has scientists worried.
Unfortunately, it is also right near the city of Pasto.
Since 1882, Nyiragongo has erupted at least 34 times. Along with this, it is famous for the lava lake in its crater. However, in 1977 the walls holding in this lake fractured and allowed the lava to flow at rates of 60 miles per hour down on unsuspecting residents.
Whether this 1977 eruption killed hundred or thousands is hard to know due to the records kept. However, what we do know is that Nyairagongo again erupted in 2002, forcing 400,000 people from the nearby city of Goma to evacuate.
Be glad that you don't have to send a letter there!
Anyway, Mount Unzen is one of the active volcanoes on the Decade Volcanoes list. Along with this, in 1792 the collapse of one of its lava domes caused a tsunami that killed about 15,000 people. This amounts to the worst devastation ever recorded due to volcanic activity in Japan's history.
