benefits & harm about living near volcanoes
:fire: :fire: :fire:
: Mount Merapi caused 13 deaths.
Lava flow :fire: - these are very slow moving, but destructive as they cannot be stopped and they set fire to everything in their path.
example: :warning: Eyjafjallajökull eruption
example: Indonesia Mount Merapi damaging crops and houses.
: Carbon dioxide (CO2) trapped in low-lying areas can be lethal to people and animals.
Sulfur dioxide (SO2) is irritating to eyes, skin and respiratory system.
Sea - during a volcanic eruption earthquakes happen, and tsunamis may be created. Also, if it is a volcanic island, the island may be destroyed, and there is no escape.
Earthquakes and tsunamis – Volcanoes and earthquakes share plates and because of this a volcano can set off an earthquake by creating movement in the plates.
For example, in 1883, 36000 people died in Kratau, Indonesia.
Transport and communication will be blocked; this will stop people getting out- or police and ambulance getting in, as the lava flows will cover and block the roads: communication with air patrol and outside help will be lost; as on the inside the roads are blocked for land transport.
Volcano eruptions can damage properties and crops and sometimes even cause death .
Volcanic pollution :explode: – While active, a volcano can be a natural source of pollution. Volcanoes release ash, gas, and magma into the air and onto the ground.
Etna is one of the ‘liveliest’ volcanoes on the planet and is almost constantly active – making it one of the best places in Europe to observe smoking craters and volcanic activity first hand. While in Italy you may also want to consider a trip to Pompeii, the ruins of a city decimated by the eruption of the Mount Vesuvius volcano and an impressive reminder of the true power that volcanoes hold.
Many people would visit volcanoes to hike and camp in the area to enjoy the scenery as it is rich in history and people can learn more about it.
geothermal energy is produced in four states--California, Nevada, Utah, and Hawaii. Today the total installed capacity of geothermal power plants in the United State is 3,200 megawatts (MW) That's the energy equivalent of three nuclear power plants. American geothermal power plants range in size from a few hundred kilowatts to more than 130 megawatts.
Hot water or steam that are caused by the eruption when groundwater comes in contact with hot rocks beneath the surface would drive turbines and produce electricity.
PRECIOUS STONES & MINERALS
diamond, gold, bauxite (aluminium ore), nickel
Volcanic rocks can be rich in precious stones and minerals, which can only be extracted from volcanic areas after millions of years. When upper layers of volcanic rocks are eroded, the precious stones and minerals can be extracted.
. volcanic soils of Java and Bali in Indonesia support the cultivation of crops such as tea, coffee and rice. But despite continuous use, the soils are more fertile than most non-volcanic areas of Indonesia
Lava and ash from volcanic eruptions break down to form fertile volcanic soils which are very favorable to agriculture because they are rich in minerals.
