поиск – A volcano is a vent in the Earth's crust from which eruptions occur. There are about 1500 potentially active volcanoes worldwide. When volcanoes erupt they can spew hot, dangerous gases, ash, lava and rock that can cause disastrous loss of life and property, especially in heavily populated areas.Volcanic gases react with the atmosphere in various ways; the conversion of sulfur dioxide (SO2) to sulfuric acid (H2SO4has the most significant impact Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into…Other volcanic gases include hydrogen chloride, carbon monoxide, and hydrogen fluoride. 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.

4 How Do Earth Systems Interact with Eruptions? | Volcanic Eruptions… – The most common type of volcanic eruption occurs when magma (the term for lava when it is below the Earth's surface) is released from a volcanic vent. Eruptions can be effusive, where lava flows like a thick, sticky liquid, or explosive, where fragmented lava explodes out of a vent.The most important constituent of volcanic gas is water vapor (forms about 90% of all the gases1) although the concentration is lower (about 60%) in gases Chemical elements Cl, F, and Br occur as acids (combined with hydrogen from water to form hydrochloric, hydrofluoric, and hydrobromic acid).Volcanic gases have been monitored to predict eruptions since their compositions are strongly affected by volcanic activities. Here, volcanic gas geochemistry is reviewed with the main focus placed on the potential use of volcanic gases as eruption precursors.
