The hazards presented by volcanic and seismic events have the greatest impact on the world’s poorest people. To what extent do you agree?

A geologic hazard is an extreme natural events in the crust of the earth that pose a threat to life and property, for example, earthquakes, volcanic eruptions, tsunamis and landslides. Volcanic hazards include ash, pyroclastic flow, lava, lahars, landslides, glacial melt and disturbances to the air quality. Seismic hazards can include the initial shaking, buildings collapsing, aftershocks, landslides and tsunamis. These hazards can effect local people, for example homes lost, a national scale, for example cities lost, or on a global scale, for example flights grounded and ash circulates around the world, as well as temporary climate change. However, while it is undisputable that these hazards effect everyone, I agree to a partial extent that they do have the greatest impact on the world’s poorest people.

Volcanoes appear in both developed and undeveloped countries. They are dictate by plate boundaries; they never appear at a transform boundary. They always appear on a divergent boundary where the two plates are pulling apart from each other, forming new crust. This creates a gentler volcano, as there is pure mantle forming the magma. They sometimes appear on a convergent boundary. When the two pieces of land are oceanic and oceanic, and oceanic and continental, volcanoes will appear. This is because you will get a subduction zone, where the denser plate will be forced under, and consequently melts. This then forms a volcano with mixed magma, both pure mantle, and melted earth’s crust, making these more violent. They do not appear when there are two continental plates.

There are times were volcanic eruptions effect both the rich and poor. The Caribbean island of Montserrat is situated on a convergent plate boundary. A
