1) over 4 million in north-east with no electricity
2) 1.5 million without water
3)ground shaking lead to building collapse and injuries
What were the secondary effects of japan earthquake

2)search and rescue operations
Secondary responses to Japan earthquake
1) by 2015 debris had been cleared
2) new housing build away from low lying areas
3) 2013 a sea wall and embankments built

What conditions does water need to be for a tropical storm to occur
26.5 degrees C
70 meters deep
Explain how a tropical storm forms
1) A strong upward movement of air draws water vapour up from the warm ocean surface
2) This evaporated air cools as it rises and condenses to form towering thunderstorm cloud
3) As the air condenses it releases heat which powers the storm and draws up more and more water from the
ocean.
4) Several smaller thunderstorms join together to form a giant spinning storm. When surface winds reach an
average of 120 km/hour (75 mph) the storm officially becomes a tropical storm.
5) the storm now develops an eye at its centre where air descends rapidly. The outer edge of the eye is the eyewall
where the most intense weather conditions (strong winds and heavy rain) are felt
6) As the storm is carried across the ocean by the prevailing winds, it continues to gather strength
7) On reaching land the storm’s energy supply (evaporated water) is cut off. Friction with the land slows it down and
it begins to weaken. If the storm reaches warm seas after crossing the land, it may pick up strength
What is the example of the tropical storm and when did it happen?
Cyclone Idai 2019

What were the secondary effects of cyclone idai
1) Rivers overflowing
2) outbreaks of cholera
What were the immediate responses to cyclone idai
1) boats and helicopters rescued people
2) donations
Secondary responses to cyclone idai
1)90,000 cholera vaccinations
2) Dutch engineers restored water supplies
3) improvements to warning systems
