Impact of Earthquakes on the Environment
Earthquakes affect things like people, buildings and nature. Strong effects
are felt by most people indoors with small objects falling over.
Risks- Seismic activity cause risks for the nuclear power industry, mining,
chemical works and structures such as bridges, dams and tunnels. Houses
may be damaged if an earthquake exceeds 5.0 on the Richter scale.
Causes- Most seismic activity occurs because of movement in the plates
that form the Earth’s crust. Earthquakes in the UK occur when stress is
released in the plate tectonics that it sits on. Countries that experience
large earthquakes and more frequent seismic activity usually lie closer to plate
tectonic boundaries. In these areas, the activity is caused by plates moving
past each other. The nearest plate boundary to the UK is the mid-Atlantic ridge.
