living with tectonic hazards
there are a number of reasons why people live in area that are prone to hazards
5) technological advancements have meant more effective monitoring of volcanoes and tsunamis
6) better building design reduces the risk for many settlements
4) a lack of education in some areas means people do not know that are at risk
7) volcanically active areas provide geothermal energy
3) many plate margins run along coastlines which are desirable places to live
8)extremely rich and fertile soils produced by volcanoes providing farming opportunities
2) people do not have a choice if they are living in poverty
9) there are jobs in the mining industry for people living near volcanoes
1) large earthquakes and volcanoes erupting do not happen very often
10) many people visit as tourists so tourism provides jobs and incomes
reducing the risks from tectonic hazards
2) prediction scientists look at historical evidence and use monitoring equipment to help them make predictions about when and where a tectonic hazard may happen
3) protection designing buildings that will withstand a tectonic hazards this is more easily done for earthquakes than for volcanic eruption
1) monitoring using scientific equipment to help detect the earning signs of a volcanic eruption or tsunami waves
4) planning authorities will identify areas most at risk from hazards
different ways in which hazards can be reduced
predicting
volcanoes prediction is based on monitoring the volcano for example before an eruption there is sometimes an increase in earthquake activity
earthquakes it is impossible to predict scientists use historical evidence to see when a earthquake is overdue
protection
volcanoes often people will evacuate if a volcano eruption occurs
earthquakes its possible to create buildings that can withstand some earthquakes in many country's these are used
monitoring
scientist will monitor volcanoes they will use remote sensors to detect changes in the volcanoes heat and shape seismometers to record any earthquakes activity tiltmeters to measure change sin the shape
earthquakes theses usually occur with out any warning
planning
volcanoes there are hazard maps created for volcanoes to show the areas likely to be affected this helps people to know which area will be effected
earthquakes maps can be produced to show critical buildings such as hospitals in the areas that are at high risk
