They are amazing and beautiful mountains but also deadly. They can block aviation, cause earthquakes and make lots of casualties, we are talking about volcanoes, the most beautifull and deadly places on Earth.
In the list bellow we will present you some of the most powerful volcanoes in the world.
- Mount Vesuvius
Of the many eruptions of Mount Vesuvius in Italy, the most famous is the eruption in 79AD. This eruption is one of the most deadliest in European history.
Mount Vesuvius violently spewed forth a deadly cloud of super-heated tephra and gases to a height of 33km ejecting molten rock, pulverized pumice and hot ash at 1.5 million tons per second, ultimately releasing 100.000 times the thermal energy of the Hiroshima-Nagasaki bimbings. The event gives its name to the Vesuvian type of volcanic eruptions, characterised by eruption columns of hot gases and ash exploding into the stratosphere, although the event also included pyroclastic flows associated with Pelean eruptions.
- Laki, Iceland
Laki or Lakagigar is a volcanic fissure in the western part of Vatanjokull National Park, Iceland, not far from the volcanic fissure of Eldgja and the small village of Kirkjubæjarklaustur. The fissure is properly referred to as Lakagigar, while Laki is a mountain that the fissure bisects.
On June 8/1783, a 25km long fissure with 130 craters opened with phreatomagmatic explosions because of the groundwater interacting with the rising basalt magma. Over a few days the eruptions became less explosive, Strombolian, and later Hawaiian in character, with high rates of lava effusuin. The event is rated as 4 on the Volcanic Explosivity Index, but the eight-month emission of sulfuric aerosols resulted in one of the most important climatic socially repercussive events of the last millennium.
- Mount Tambora, Indonesia
Mount Tambora, or Tamboro, is an active stratovolcano in the northern part of Sumbawa, on of the Lesser Sunda Islands of Indonesa. It was formed due to the active subduction zones beneath it, and before its 1815 eruption, it was more than 4.300 meter high, making it one of the tallest peaks in the Indonesian archipelago.
Tabmbora’s 1815 eruption was the largest in recorded human history and the largest of the Holocene (10.000 years ago to present ). The magma chamber under Tambora had been drained pre-1815 eruptions and underwent several centuries of dormanci as it refiled.
Novarupta is a volcano that was formed in 1912, located on the Alaska Paninsula in Katmai National Park and Preserve, about 290 miles southwest of Anchorage. Formed during the largest volcanic eruption of the 20th century, Novarupta released 30 times the volume of magma of the 1980 eruption of Mount St. Helens.
- Mount Pinatubo
Mount pinatubo is an active stratovolcani in the Zambales Mountains, located on the tripoint boundary of the Phillippine provinces of Zambales, Tarlac and Pampanga, all in Central Luzon on the northen island of Luzon.
Its eruptive history was unknown to most before the pre-eruption volcanic activities on 1991, just before June.Pinatubo was heavily eroded, inconspicuous and obscured from view. It was covered with dense forests which supported a population of several thousand indigenous Aetas.
