OBJECTIVE FORESTRY

Detailed explanation-1: -Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. People have died from volcanic blasts. Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.

Detailed explanation-2: -Yes. Human activity can probably cause volcanic eruptions, albeit indirectly. Regardless, human activity affects volcanic disasters in several other ways. First, let’s look at how humans can cause volcanic eruptions.

Detailed explanation-3: -Injected ash falls rapidly from the stratosphere–most of it is removed within several days to weeks–and has little impact on climate change. But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.

Detailed explanation-4: -Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber.

Detailed explanation-5: -Lava flows, scorching ash and tsunamis – a volcanic eruption can devastate huge areas more suddenly and with greater intensity than almost any other natural disaster. Ash clouds alone can paralyse economic activity and cause substantial financial losses, even when there is little property damage involved.
