why Do People Live In Tetonically Active Areas? and methods used to test them Flashcards
advantages of living in tectonically active areas
cheap energy (geothermal power)
fertile soil for crops
opportunities such as views and landscapes
minerals provide jobs and diamonds can be mined
historic
disadvantages of living in tectonically active areas
not enough money to move
want to move but don’t want to leave family
don’t know when the volcano will erupt – not enough knowledge
how do seismic waves work?
VOLCANOES
scientists use seismometers
volcanoes experience increase in frequency
yes it is effective
how do you gas emissions work?
VOLCANOES
magma rises into magma Chambers
sulphur dioxide amount is used as a signal
yes it is effective
how does ground deformation work?
VOLCANOES
scientists measure the tilt of the slope and tracked changes in the rate of swelling
Yes it is effective
How do satellite images work?
VOLCANOES
satellites are used to monitor the heat of volcanoes at the surface
yes it is effective
how do you Seismic waves and after-shocks work?
EARTHQUAKES
seismometer are used
foreshock are used by monitoring seismic waves
no it is not effective
how does animal behaviour work?
EARTHQUAKES
animals react to an earthquake before the event and humans
no it isn’t effective
how do you laser beams work?
EARTHQUAKES
Detect plate movement by directing The beam across the fault line
no it isn’t effective
How could building features be adapted to decrease the damage of an earthquake?
rolling weights on roof
safe areas for people to gather
numbers on roof for helicopters to identify buildings
lattice work steel cage to stabilise building
