The benefits man can reap from volcanoes are, the land around the volcano that erupted would having fertile soil for agriculture, it will also have valuable minerals found in the volcanic areas, examples are, copper, gold, sliver and more. Benefits of volcanoes after a volcanic eruption, the soil becomes rich due to the nutrients from the volcano precious stones and gems that were once deep within the earth are brought to the earth's surface and will contribute greatly to the economy of the country. Another benefits to volcanoes are the precious gems, minerals and building materials that eruptions make available for instance, stones like pumice volcanic ash and perlite (volcanic glass) are all mined for various commercial uses these include acting as abrasives in soaps and household cleaners. About temperature anomalies caused by the volcanic eruption] rampino mr and self s (1994) climate-volcanic feed-back and the toba eruption of ~ 74 000 years. The problem is that many civilizations developed near volcanoes for this reason—with sometimes deadly effects volcanic activity can also create many mineral resources such as gold, sliver, nickel, copper, and lead.
Sulphur dioxides cause environmental problems, because they are converted to sulphuric acid in the stratosphere the main cause of acid rain furthermore, sulphate aerosols are formed, which reflect solar radiation and absorb heat, thereby cooling the earth. Figure 1 the 1815 eruption of mount tambora caused much loss of life and changed the global climate for one to two years this is an image of the volcano today as seen from the space shuttle. Health benefits of volcanic ash on skin have been known for centuries by the native melanesians - especially those that live near any of the nine (9) active volcanoes of vanuatu. Volcanic ash often contains minerals that are beneficial to plants, and if it is very fine ash it is able to break down quickly and get mixed into the soil perhaps the best place to look for more information about this would be to look up references about some of the countries where lots of people live in close proximity to volcanoes and make use of the rich soils on volcanic flanks.
1) volcanoes provide resources for energy extraction, also known as geothermal resources this involves heat from the earth's crust is being converted to energy the big advantages to this type of energy are that it is very clean and the resources are nearly inexhaustible. In march-april 1982, three explosive eruptions of el chichón volcano in the state of chiapas, southeastern mexico, caused the worst volcanic disaster in that country's history villages within 8 km of the volcano were destroyed by pyroclastic flows, killing more than 2,000 people. Volcanoes can affect people in many ways, for example houses, buildings roads can be completley covered by ash, and if the ash is wet or heavy it can cause suffacation gases that it let off can seriously harm someone especially if they have respiratory problems. During the 1970s and 1980s, sporadic volcanic explosions caused shock waves that broke windows and car windshields, and the volcanic activity regularly affects air traffic arriving and departing from the nearby kagoshima airport.
The eruption of the eyjafjallajökull volcano in iceland on 20th march 2010 affected the economic, political and cultural activities in europe and across the world there was an extensive air travel disruption caused by the closure of airspace over many countries affecting the travel arrangements of hundreds of thousands of people in europe and elsewhere. Some of the good ways that volcanoes affect people include producing spectacular scenery, and producing very rich soils for farming gases water vapor, the most common gas released by volcanoes, causes few problems. Pyroclastic flows are a common and devastating result of some volcanic eruptions they are fast-moving fluidized bodies of hot gas, ash and rock (collectively known as tephra) which can travel.
Problems caused by volcanoes they can cause loss of life especially when they erupt unexpectedly as in the destruction of pompeii can cause destruction to crops when they erupt and via lava flow as recently happened in hawaii. Volcanic eruptions can cause earthquakes, fast floods, mud slides, and rock falls lava can travel very far and burn, bury, or damage anything in its path, including people, houses, and trees the large amount of dust and ash can cause roofs to fall, makes it hard to breathe, and is normally very smelly. Benefits of volcano monitoring far outweigh costs-the case of mount pinatubo the climactic june 1991 eruption of mount pinatubo, philippines, was the largest volcanic eruption in this century to affect a heavily populated area.
Many times people think that volcanic eruptions affect the economy through the destruction inflicted upon the landscape during an eruption: lahars and pyroclastic flows destroying bridges and. Occasional eruptions of volcanoes around the world have led to concerns about volcanic ash drifting into canada and the respiratory problems it might cause volcanic ash is formed during explosive volcanic eruptions volcanic ash is made of fine rock fragments, minerals and glass the ash is hard. Inhalation of volcanic ash can be very detrimental to human health, due to the harmful aerosols and poisonous gases the ash is made up of health effects inlcude respiratory problems, eye problems, and skin irritiation. Health exposure to volcanic ashfall rarely endangers human life directly, except where very thick falls cause structural damage to buildings (eg roof collapse) or indirect casualties such as those sustained during ash clean-up operations or in traffic accidents.
The main problems specific to volcanoes experienced by volcano tourists and those working in volcano tourism are cuts and grazes from falls on sharp volcanic rocks, and respiratory and eye irritation when exposed to fumarole or crater gases. Volcanic air pollution or vog occurs due to the release of sulphur-di-oxide or so2 from active volcanoes and has deadly effects on nearby inhabitants kilauea volcano has been active for past 25 years, with its first eruption in 1983 and most recent on march 29, 2008. Each is caused by a rising and growing chamber of hot molten rock known as magma in super eruptions the magma chamber is huge, sparks said the eruption is rapid, occurring in a matter of days.
