Beautiful landscapes are created in the after math. This brings tourism which creates jobs and money for the people. It makes the places unique, creating an interesting landscape.
“It should be emphasized that the short term hazards posed by volcanoes are balanced by benefits of volcanism and related process over geologic time.” – Tilling, 1985 Ref: http://volcan.wr.usgs.gov/

Benefits from lava and volcanic ash
It may take generations for the lava to turn into a fertile land. Lava breaks down to form some of the most fertile soils on earth. This is due to the fact that lava is rich in minerals. This helps in farming. For a farmer, a volcanic eruption that produces less than 20cm of ash is a blessing. The ash is full of nutrients which enrich the soil. Example, The lush land around Vesuvius has been fertilized by ash from regular eruptions over the last 20 centuries. The ash supports grape harvest, which in turn supports the local wine industry. Rich soil is created. This helps to make crates job for people.
Benefits from volcanic rocks
Volcanic rocks are found in many areas and used as construction material. They are also used as for building roads and for landscaping. Beautiful landscapes are created in the after math. This brings tourism which creates jobs and money for the people.
Benefits from Hot spots
Hot spots are used by people as a source of geothermal energy. Steam from volcanic hot springs are used to spin turbines and generate electricity. They can also be source to provide hot water to people living near volcanoes. These are found in Japan, USA and Iceland.
Creation of metal deposits
Underneath the old volcanoes in Chile and Peru (South America) there are large deposits of copper. Copper is a very useful metal in conducting electricity in houses and office buildings.
