Pyroclastic flow

“Dante’s Peak” demonstrates the volcano as its star, stealing the spotlight from the obstinate grannies, and the romantic relationship between the heroic volcanologist and the town mayor. The film starts by introducing the terror of how destructive, volcanoes can be. There are two main activities that are associated with this eruption, the bombs, and the ash fall. The introduction, transitions to Dante’s Peak, which is a Composite volcano (Stratovolcano). Dante’s Peak starts indicating signs…

The pyroclastic flow, a fast current of gas and rock, reached speeds of 400 miles per hour and temperatures of over 1000° Fahrenheit. At contact with the pyroclastic flow, all the fluids in the victim's body would change to steam. If the person survived that, he would have to avoid asphyxiating on the pernicious gases and ash. Pompeii…

In 79 CE, August, Mount Vesuvius had a significant eruption, that went on for nineteen hours, burying an ancient Roman city for seventeen centuries. This city was near the modern Naples within the Italian Region of Campania. The buildings and many of the people were buried and lost until the discovery made in 1738. This city is known as the lost city of Pompeii. Mount Vesuvius is a stratovolcano that consists alternate layers of ash and lava. Stratovolcanos have two types of eruption, one…

Taupo Volcanic Zone The Taupo Volcanic Zone is a highly active volcanic region situated in the central part of the North Island in New Zealand. The Taupo Volcanic Zone (TVZ) stretches from Ohakune in the south of the Bay of Plenty to White Island in the north. It is estimated that the Earth’s crust below the Taupo Volcanic Zone may possibly be as small as 16 kilometers think and currently moves approximately 8mm per year. The TVZ is named after Lake Taupo, the caldera of the formaly largest…

Seismologist with the United States Geological Survey are usually the first to arrive in volcanic areas, to predict volcanoes eruptions and to alert people so they can get evacuated safely. One problem with the predictions is that the size and direction can’t be predicted. With the new technology and equipment, it's becoming easier to predict volcano eruptions correctly. In 1991 Mount Pinatubo in the Philippines erupted causing many tribes to evacuate their homes. Researchers from the…

On June 15, 1991, Mt. Pinatubo erupted. Volcanologists successfully predicted the eruption and issued a warning ahead of time, which allowed minimal casualties. The stakes for failing to predict an eruption accurately are high. If one fails to predict an eruption and it happens then lives and property can be lost; however, if one does predict and eruption and it does not happen then one’s personal reputation can be damaged or destroyed. In the case of Mt. Pinatubo, the U.S. volcanologists…

also made of volcanoes. Out of the volcanoes that are on the island, only 108 are active. Out of the volcanoes that are on our project, Volcano 1, Volcano 3, Volcano 5, and Volcano 6 are active. The people in Japan can suffer from lava flows, tephra, pyroclastic flows, landslides, lahars, and…

In Indonesia, the pyroclastic flows hit the surrounding sea at such great speed that it created a powerful tsunami; its wave was still two metres high when it hit Java, an eastern island of Indonesia located 500 km away. In the years following the eruption, many still saw the floating islands of pumice in the surrounding seas. The ash flows, the tsunamis, and the starvation that followed the eruption put the death count at around…

Krakatoa erupted in 1883, killed many, affected climate worldwide, and may do it all again. Krakatoa affected many people all over the world, mostly in bad ways. A lot of people think that Krakatoa is in the past, but it’s still active and very dangerous. A lot of time and energy has gone into studying volcanoes like this. As you can probably guess, it's not the safest line of work. The eruption of Krakatoa was the loudest sound in modern history. It reached thirty thousand miles away.…

The explosion caused an earthquake and tsunami because of the pyroclastic flows and collapse of the caldera. These other devastations caused flooding and disaster on several of the other Indonesian islands. The death toll was sky high and as well as the largest death count recorded by a volcano, the ash filled the skies…
