VOLCANIC ERUPTIONS 2. Although gases usually blow away rapidly, it is possible that people who are close to the volcano or who are in the low-lying areas downwind may be exposed to levels that may affect health. Although volcanic ash can decrease regional visibility for a few months after the eruption, sulfur compounds injected into the stratosphere form sulfur aerosols that can reflect a… Read More As a result, they are extremely destructive. All U.S. v… Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires. during a volcanic eruption Use an N95 dust mask to protect yourself from pulmo-respiratory injuries and diseases. The different types of volcanic activity can best be understood by making comparisons, and in this section two specific eruptions are compared—the 1991 eruption of Mount Pinatubo (a classic example of explosive volcanism) and the 1984 eruption of Mauna Loa (illustrative of effusive volcanism). Loud rumbling sounds were also felt and heard from the volcano island. They also allow a world to vent its heat. Some volcanoes typically produce highly explosive eruptions, such as in the subduction zones of Alaska and the Pacific northwest, and others produce less energetic eruptions, such as in Hawaii. Explosive eruptions generally involve magma that is more viscous and has a higher gas content. The best way to do protect yourself and your family is to follow the advice of local officials. READ: Causes, Effects and Types of Landslides. Over geologic time, volcanic eruptions and related processes have directly and indirectly benefited mankind: Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations. Strombolian eruptions involve moderate bursts of expanding gases that eject clots of incandescent lava in cyclical or nearly continuous small eruptions. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Volcanic eruption can also release sulfur. Some said Etna's Monday eruption was the most powerful during its recent burst of activity, with one expert saying an eruption of its kind had not been seen for decades at the mountain. The rate at which pressure is reduced also controls the explosiveness. One elderly person died while at sea en route to Puerto Montt. However, heavy gases such as carbon dioxide and hydrogen sulfide can collect in low-lying areas. Raung volcano eruption. According to Attila Kilinc, a professor at University of Cincinnati who studies volcanoes in Hawaii ad Montserrat, there are several factors that triggers the volcano to erupt but there are three that predominates it and this are 1) the buoyancy of the magma, 2) the pressure from the exsolved gases in the magma and 3) the injection of a new batch of magma into an already filled magma chamber. The uprushing gases and volcanic fragments resemble a gigantic rocket blast directed vertically upward. Volcano - Volcano - Six types of eruptions: Volcanoes are frequently classified by their size and shape (as is described in the section Volcanic landforms), but they can also be classified by their eruptive habits. The explosive eruption of the volcano continues at elevated levels. Plinian eruption clouds can rise into the stratosphere and are sometimes continuously produced for several hours. Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. Some volcanic eruptions are explosive and others are not. You can do many things to protect yourself and your family from the dangers a volcanic eruption can cause. Some eruptions are terrible explosions that throw out huge amounts of rock and volcanic ash and can kill many people. Clean everything around and check all damages incurred. Fault lines are the weak areas, cracks, or openings in the earth’s crust. 2. The explosivity of an eruption depends on the composition of the magma. For more information on volcanoes and health, see the following sources: Centers for Disease Control and Prevention. In response to each eruptive event, This combination is explosive because the gases cannot easily boil out; rather, they remain pent up until they reach the pressure at which they blow the viscous magma into fragments.
