Top 10 Most Dangerous Active Volcanoes

 

1.Mount Fuji, Japan

One of the most famous peaks on the planet, Mount Fuji is a potent symbol of Japan. Scaling its heights is a national must-do. Although still classed as active, Fuji hasn’t erupted since 1708, so the threat of being consumed by hot magma is thankfully fairly low..

2.Mount Bromo, Indonesia

Indonesia does quite well for volcanoes, if it's right to put it like that. Ijen, Ranjani, Semeru, Kelimutu and many more. Mount Bromo is but one in a series of peaks in East Java, sitting in the middle of the evocatively-named Sea of Sand. Bromo went bang big style in 2011.

  3.Popocatepetl, Mexico

Try saying that after a few mezcals. Looming over Mexico City (if the smog thins enough to see it), Popocatepetl provides an anxious presence. With increasing activity, including several eruptions of steam and ash just last month, it is looking odds-on for a big blow in the near future. 

  4.Mt. Kilauea, Hawaii

Kilauea on Hawaii’s Big Island claims the title of the world’s most active volcano. Take a boat trip to see one of its most spectacular sights – red hot lava oozing into the ocean which causes the sea to boil and vaporise into white plumes of steam.

5.Sakurajima, Japan

 This composite volcano in Japan was once its own island, but lava flows in its 1914 eruption caused it to connect to the mainland. Many experts refer to it as the “Vesuvius of the east”, due to its high level of volcanic activity.

Every year, thousands of small explosions come from Sakurajima’s peak, throwing up ash over the surrounding areas. However, a major eruption could have deadly consequences for the 700,000 residents of Kagoshima, who live just miles from the Volcano. The city even has special volcano shelters where people can go to take cover from falling debris.

 6.Galeras, Columbia

 Located in Southern Columbia near the border with Ecuador, Galeras has been active for at least 1 million years. It erupts frequently, with its first recorded eruption dating back to 1580. More alarming is the fact that a city of 450,000 residents – the city of Pasto – lies on its eastern slope.

While it went dormant in 1978, it went active again in 1988 after just 10 years. When scientists held a Decade Volcano conference in 1993 to address the dangers of Galeras, an unexpected eruption occurred, killing 6 scientists and 3 tourists. Since 2000, it has erupted almost every year, spouting out ash and lava and causing tremors in the region.

 

7.Mt. Merapi, Indonesia

 Mt. Nyiragongo is one of the most active volcanoes on the African continent. It’s well known for its large lava lakes, which frequently appear in its crater. Nyiragongo poses a unique threat to surrounding communities, as nowhere in the world does a steep sided stratovolcano carry such a large lake of fluid lava.

In fact, from 1894 to 1977, Nyiragongo’s summit crater was filled with a large, active lava lake. When the walls of the crater fractured on Jan 10, 1977, the lava lake drained within an hour, causing massive lava flows of over 60 miles per hour. These flows quickly overwhelmed local villages, causing several thousand people.

 8.Taal Volcano, Philippines

 The Taal Volcano is a cinder cone volcano. It is located on the island of Luzon, Philippines where it lies at the middle of Lake Taal. It lies just 31 miles from Manila – the capital of the Philippines and home to 1.6 million people.
The Taal Volcano has had 33 recorded eruptions since 1572. While most of these eruptions are confined to the intracaldera area, some eruptions devastate the entire region with its fallout. Altogether, it’s estimated that 5,000-6,000 people have been killed by eruptions at Taal. Even today, the only safe way to view the active Taal Volcano is from a safe distance. Of course, that doesn’t stop adventurers from trekking on “Volcano Island”.

 

 9.Mauna Loa, Hawaii

In terms of volume and surface area, Mauna Loa is the largest volcano in the world. It is also one of the 5 volcanoes that make up the Island of Hawaii, all the way in the middle of the Pacific Ocean.
Mauna Loa has been erupting regularly for at least the past 700,000 years, with its most recent eruption occurring in 1984. The most significant hazard Mauna Loa poses to surrounding communities are its lava flows. Although most of the flows from Mauna Loa advance at a slow pace, posing little danger to human life, major eruptions can cause fast moving flows. In 1950 for example, the village of Ho’okena Mauka was destroyed by flowing lava. The intense 1984 eruption saw lava flows that moved towards the highly populated Hilo, but didn’t reach any buildings.

 10.Ulawun, Papua New Guinea

The first recorded eruption of Ulawun was in 1700. Several thousand people live near the volcano.There have been 22 recorded eruptions since the 1700s. The last few years have seen almost constant activity at Ulawun, with frequent small explosions. Eruptions originate from a central crater. Its eruptions devastated the NW flank of Ulawun and modified the summit crater. An eruption in 1980 ejected ash to 60,000 ft and produced pyroclastic flows which swept all flanks of the volcano and devastated an area of 20 sq km. The most serious volcanic hazard at Ulawun volcano is catastrophic structural collapse, producing an eruption which could devastate hundreds of sq km in area.
Ulawun volcano is 400 m higher than most of the volcanoes in the Bismarck which indicates it may be at the limit of structural stability. Seismic activity remained high at Ulawun Volcano in 2008. A magnitude 5.1 earthquake hit 10 km west of Ulawun volcano on 28th May 2009. On 14-15 February 2010 ash emissions from Ulawun volcano reached a height of 3.7 km and drifted 95 km.

Ulawun is such a dangerous volcano which started erupting from 18th century. Because of dangerous volcanic eruption in year 1980, its ashes ejected upto 18 kms and destroyed an area of 20 square kms. It’s the dangerous volcano which having the highest peak in Papua New Guinea. This dangerous volcano was lastly erupted in year 2010, whose ashes emitted upto 3.7 kms. - See more at: http://ohtopten.com/top-10-most-dangerous-volcanoes/#sthash.LtHpJFjF.dpuf
