Where is the most dangerous city in the world?

Poorly understood and most active volcano in the world Nyiragongo, located in Central Africa. Its height is about three kilometers. In the middle of the volcano hides the largest lava lake known to science, a width of about 200 meters and a depth of over two kilometers. Twice lava flows during the eruption of Nyiragongo attacked the town of Goma which is located on the Eastern border of the Republic of the Congo. Despite the fact that the city of Goma lies at the foot of an active volcano, its population is growing due to refugees who are hiding in the city from the rebels. The population of the city of Goma has already exceeded one million.

In 1977 the lava with a record speed of 95 km/hour rushed to the city. Even to urban neighborhoods, it is not reached, but still there were hundreds of victims. In 2002, the lava has penetrated to the center of the city of Goma and destroyed on its way 14,000 homes. The building was filled to the level of the second floor. Residents were forced temporarily to leave the city. Scientists believe that the volcano is still not cleared in full force, and these two eruption was just a warm-up for him. A new eruption could completely destroy the city like at the time Vesuvius destroyed Pompeii. Goma is the most dangerous city in the world.

The eruptions in 1977 and 2002, was not traditionally a vertex, but rather a fissure. But they left behind a 10-lane highway of lava. The city threatened not only the volcano, and lake Kivu, where vast reserves of methane and carbon dioxide. During the eruption, these gases are released, and the toxic cloud will penetrate into the city of Goma.

The study of the volcano Nyiragongo interfere with ongoing for 20 years of military conflicts in the region. But, nevertheless, scientists study the volcano. However, they do it under the protection of soldiers. After all, it is important to know the date following the eruption of Nyiragongo, which can completely destroy the city. And to help in determining the time of the next eruption can only be a sample of fresh lava, which scientists extract with risk for life.
