10 Most Dangerous Active Volcanoes In The World



     Every volcano will have a certain time to cause eruptions and those were thought to be a punishment from the Gods.

     As the scientific research said that the volcanic eruptions are caused due to the overheat magma pushing up from the mantle through vents in the earth's crust. Of course, that doesn't make their explosive effects any less calamitous.

     Here is the list of dangerous and active volcanoes mostly erupts and damage the surrounding places and environment at a large scale.

               Top 10 Dangerous volcanic eruptions:

10. Mauna Loa, Hawaii


       The Island of Hawaii in the U.S. state is formed with the group of 5 volcanoes, in which one of them was "Mauna Loa" near pacific ocean. The  Mauna Loa is the biggest subaerial volcano in both measures of mass and volume, This volcano has historically been  reviewed as the largest volcano on Earth.

      Mauna Loa written records show that 1950 eruption was the largest eruption from the southwest rift zone. It was noteworthy, for lava erupted from a nearly 20-km-long fissure along the middle portion of the rift zone. One of the notable things about this Mauna Loa eruption is that the lava flowed to the sea in the less than 4 hours.

9. Taal Volcano, Philippines


     Taal Volcano is usually considered as the cinder cone volcano. It is located on the island Luzon, the Philippines where it lies in the middle of Lake Taal. This volcano is situated just 31 miles from Manila( Capt. of Philippines) and a home to 1.6 million people.

   Taal Volcano has the count of 33 recorded eruptions since 1572. While most of these eruptions are limited to the Intra caldera area, some eruptions caused damaged to the entire region with its fallout. Overall, it is evaluated that nearly 5,000-6,000 people have been killed by these eruptions at Taal. Till today, the only safe way to see the active volcano is just by seeing it from a long distance. Of course, that doesn’t stop adventurers from trekking on “Volcano Island”.

8. Ulawun, Papua New Guinea


     In Papua New Gunea, Ulawun is the one of the most active volcanoes and it's eruptions are originated from its central crater. This volcano has the count of 22 eruptions since the 1700s. In the recent years, the activities at Ulawun are considered to be consistent and local residents constantly witnessing the small explosive eruptions will spread the ash and lava into the environment of surrounding areas.
 
     Due to its height, the biggest threat posed by Ulawun is a catastrophic structural collapse, which will cause an eruption and due to its eruption, it can damage nearly 100s of square km of surrounding land.

7. Mt. Nyiragongo, Democratic Republic of Congo


     Mt. Nyiragongo is one of the most active volcanoes in the African continent. It is famous for its large lava lakes, which regularly appeared in its crater. Nyiragongo poses a unique and harmful threat to its nearer regions, as nowhere in the world does a steep-sided stratovolcano carry such a large lake of fluid lava —sometimes quite destructively. 
      
      In 1977 when the lake wall was broken, a quite large lake spilled and flows traveling at 60 mph destroying nearby villages, killing and injuring thousands. Nearly, 147 people died in an eruption as recent as 2002, and another 120,000 lost their shelters.

6. Mt. Merapi, Indonesia


     Since 1548, Mt. Mount Merapi, Gunung Merapi is a most active stratovolcano located on the border of Central Java and Yogyakarta, Indonesia and has erupted regularly.  It has been active at least 10,000 years. However, Thousands of people live on the flanks of the volcano, with villages as high as 1,700 meters above sea level. But in 2010, an eruption killed 353 people and left 320,000 more without homes.

The name of this mountain means “Mountain of Fire." It is Indonesia’s most active volcano, and it has produced a record amount of lava flow. Measured in terms of flow alone, it is the most active volcano in the world. 

5. Galeras, Colombia


     Galeras is an Andean stratovolcano which is as high as 4,276 meters above sea level located in the Colombian department of Nariño, near the departmental Capital Pasto. Till today, it is the most active volcano in Colombia. In 1993, this eruption killed nine people, including six scientists who went to collect the sample gasses and take gravity measurements in an attempt to be able to predict future eruptions.

4. Sakurajima, Japan


     Sakurajima is an active stratovolcano and also a former island in Kagoshima Prefecture, Kyushu, Japan. Sakurajima is a strato mountain. Its summit has 3 peaks, Kita-Dake (northern peak), Naka-Dake (central peak) and Minami-Dake (southern peak). The lava flows of the In 1914, the  eruption occurred and the lava flows from former island to Osumi Peninsula and they connected with the lava flacks

      Although, the volcanic activity still continues, spreading out the large amounts of volcanic ash into the environment. Due to those eruptions, the Volcanic ash built the white sands highlands in the region. In September 2015, the Japan Meteorological Agency alerted- Level 3 signal instructed that the volcano is active and should not be approached. The most recent eruption started on February 5, 2016. If a major eruption occurs, 700,000 residents in the Kagoshima City will be in immediate danger.

3. Popocatepetl, Mexico


       Popocatépetl  is an active volcano, located in the states of Puebla, Mexico, and Morelos, in Central Mexico, and lies in the eastern half of the Trans-Mexican volcanic belt at 5,426 meters, it is the second highest peak in Mexico and after Citlaltépetl at 5,636 meters. It is connected to the Iztaccihuatl volcano to the north by the high saddle known as the Paso de Cortés.

     This volcano erupted most recently in 2000. If the Mexican Govt. didn't alert those people, then that eruption would have been in danger of losing their lives if they had not been evacuated in time. Nine million people live within the blast radius. If there is ever a major eruption, it will be the biggest disaster. This note-taking point makes Popocatepetl one of the most dangerous volcanoes  as well as the most active on the planet.

2. Mt. Vesuvius, Italy


     One of the most famous, dangerous, and active volcanoes on the planet is Mt. Vesuvius. Anyone who has attended a school will know the history of catastrophic eruption in 79AD, which destroyed the cities of Pompeii and Herculaneum. The volcanic ash preserved the two areas, making them few of the top known archaeological digs on earth. Vesuvius has an eruption cycle nearly every 20 years. The last eruption was in 1944, so the mountain is overdue for its next eruption. Three million people are located within the blast radius and close to the crater. This is another volcano which poses a serious risk to a large number of people.

1. Yellowstone Caldera, United States of America


    The top most dangerous volcano on our list of active volcanoes is the Yellowstone Caldera. The national park’s active volcanic caldera welcomes nearly three million visitors per year. Its hot springs and geysers are beautiful to behold, but they are also potentially deadly. Yellowstone is a supervolcano. In fact, the last known major eruption of a supervolcano happened in Yellowstone 640,000 years ago. If Yellowstone blows in future, then it is estimated that 87,000 people would be killed instantly. The entire western USA would be devastated, and the ash in the environment would also impact the ecology and human health throughout the country and even throughout the world. The explosion would be a worldwide disaster of unparalleled proportions, and there is no way to predict how far its disaster would extend.
