prediction strategies
radon gas sensor - when plates move its released
water table level - fluctuate during earthquakes
Gas def.
sulphur dioixde , water vapour , co2
prevention strategies
Cant stop earthquakes
earthquake resistant buildings
increasing public awareness
ash cloud
mini peices of rock and glass thrown into atmosphere
lahar
mudflow - down the side of volcanoe
pyroclastic flow
fast moving super heated gas and ash
volcanic bomb
ejected from the volcanoe - large fragment
warning signs-volcanoes
release of gas
temperature rise in sourrounding area
monitering techniques for volcanoes
thermal imaging
satelite cameras
gas sensor - increased in chemical levels like sulphur
preparation for volcanoes
emergency supply of provisions
hadley cell
largest cell extending from equator to 30 degrees north
ferrell cell
air flows poleward 60 and 70 degrees latitude
polar cell
smalles/weakest from poes to ferrel
low pressure
caused by hot air rising
stormy cloudy weather
higher pressure
cold air sinking
clear skies
how are tropical storms formed
warm moist air
once 27 degrees leads to low pressure and rises
causing thunder storm and air to be sucked in from trade winds
coroliss effect where trade winds blow opposite and earth spins oppsoite
as storm gains more power it cools in middle
74mph
protection - tropical storms
projects to improve protection
planning - tropical storms
getting people and emergency services ready to deal with impacts
monitering constantly-tropical storm
can help to warn or predict the tropical storm
primary effects of a tropical storm
destroy buildings
netwrok
storm surges-higher waves
secondary effects of tropical storms
left homeless causing stress and poverty
lack of sanitation
natrual change
orbital changes
sun spots -more energy to earth
international agreements
cut greenhouses gases with goals
urban strategies for reducing congestion?
bus priotised lanes
bike parks
bike fee
