Opportunities created by Volcanic Eruptions
Fertile Soils
Weathering of volcanic products
such as ash, lava and rock releases valuable
nutrients
+ mineral into the soil
⇨ enriches + improves soil
characteristics
e.g. moisture retention
Hawaii
Weathering of lava is quick ⇨ growth of vegetation + rapid soil formation ⇨ attracts larger populations
Italy
Vesuvius ⇨ olive vineyards + fruit
Geothermal Energy
Heat
from magma sources close to the surface in volcanic areas ⇨ source of
energy
production
Superheated steam
(created by the of heating water in permeable rocks) turns
turbines
⇨ generates
electricity
Renewable
+
sustainable
(weather sources are unreliable)
Reykjavik
(Iceland) uses this energy to heat
greenhouses
for vegetables
Tourism
Scenery
associated with volcanoes e.g. lava flows, geyser, attract
tourists
Economic
benefit -
multiplier effect
- creates business for hotels + cafés ⇨ improves local economy
Blue Lagoon, Iceland
⇨ Positive effects on skin ⇨
Spas
- water cooled + pumped to lagoons ⇨ attracts tourists from around the world
Minerals
Copper, gold, silver, lead, diamonds
Rising
magma
may
cool
+ harden beneath the volcano
⇨
Hot water
circulates
within
this cold magma +
metals
are taken by the water +
redeposited
in greater concentrations
Mining
⇨ creates
economic
opportunities through jobs + value of mined minerals
Granite
Formed through volcanic
eruptions
Durable
building material
+ can be used for several purposes
