There is so much happening when a volcano erupts. In fact, strictly speaking, the termvolcanorefers to just such a vent, although it can also refer to the landform created by the accumulation of solidifiedlavaand volcanic debris near the vent. But the smallest particles of dust get into the stratosphere and are able to travel vast distances, often worldwide. . Ash and chemicals from the eruption can also generate risk of food and water contamination, and compromise basic services, like water, transportation, communications and health services. There continues to be efforts to reduce uncertainties and improve estimates of present-day global volcanic CO2emissions, but there is little doubt among volcanic gas scientists that the anthropogenic CO2emissions dwarf global volcanic CO2emissions. Can an eruption at one volcano trigger an eruption at another volcano? Volcanic gases react with the atmosphere in various ways; the conversion of sulfur dioxide (SO2) to sulfuric acid (H2SO4has the most significant impact on climate. Volcanic eruptions produce hazardous effects for the environment, climate, and the health of the exposed persons, and are associated with the deterioration of social and economic conditions.

MeSH Volcanologistscannot yet predict a volcanic eruption. An interagency volcanic ash response plan, developed in 2011, details how state, federal and local agencies should respond to a volcanic eruption in the region that can cast ash throughout the area. People have died from volcanic blasts. Volcanic eruptions are responsible for releasing molten rock, or lava, from deep within the Earth, forming new rock on the Earths surface. 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. Eventually, some of the magma pushes through vents and fissures tothe Earth's surface. The Volcanology Institute cautioned that fine ashfall could cause breathing problems, especially among young children and the elderly, and advised the public in affected areas to use face masks. In the early 1960s, the emergence of thetheory of plate tectonicsstarted a revolution in the earth sciences. The volcanoes ofHawaiiare good examples of hotspot volcanoes. Volcanologists from the U.S. Geological Survey accurately predicted the June 15 eruption of the Pinatubo Volcano in the Philippines, allowing for the timely evacuation of the Clark Air Base and saving thousands of lives.
