geography - CASE STUDIES global hazards

Primary impacts

happening during or immediately after the disaster

Secondary impacts

happens after the disaster (after days or weeks)

name a tectonic hazard you have studied

Turkey and Syria earthquake 2023

name 2 weather hazards you have studied

Hurricane Dorian 2019

and UK drought 2022

What was the Turkey and Syria earthquake measured on the Richter scale?

7.8

What was the main cause of the Turkey and Syria earthquake?

The Arabian plate moved north towards the Eurasian Plate, Turkey and its Anatolian plate was squeezed between the two

how many aftershocks were triggered after the Turkey and Syria earthquake?

2

State 4 effects of the earthquake

• 230,000 buildings destroyed

• over 55000 people dead

• fires, landslides and floods triggered

• Aid was difficult to reach Syria

Turkey is an ___ with a population of 85 million.

EDC

Syria is an ___ with a population of 21 million.

LIDC

Explain how the Turkey and Syria earthquake 2023 was responded to

• as the earthquake stopped, local people began to search for survivors in rubble.

• 3.2 million food/medical supplies distributed

• Turkish Red crescent provided hot meals

• US donated £185 million so that destroyed buildings could be improved

• 77 search and rescue experts offered by the UK, along with specialist equipment

Explain 3 consequences of the UK drought

• limit usage of water, people were restricted to the amount of water they could use

• Farmers faced reduced crop yields, contributing to increased food prices

• amount of wildfires increased by 500, harming wildlife and ecosystems

What was the cause of the UK 2022 drought?

5 months of below average rainfall, above average temperatures (40)

State 3 responses to the UK 2022 drought

• Hosepipe bans

• Usage of water restricted

• Water companies offered water

Assess one technological development used to mitigate the impacts of a tectonic hazard. [8]

early warning systems

• automatic texts that are sent to phones when seismometers detect potential earthquakes

• an advantage of the technology is that it gives a few seconds warning which can be enough for people to go to safety

• a disadvantage of this system is it is very expensive

• In LIDCs, people may not have devices such as phones so may not get the message

Hurricane Dorian was a category __ hurricane

5

describe the movement of Hurricane Dorian 2019

Started in the Atlantic ocean and moved west to the Bahams

how was the hurricane Dorian 2019 formed?

• ocean temperature over 26

• low pressure, warm, moist air rises and condenses. releasing latent heat

• rising air creates low pressure zone near surface, which pulls in water

• earths rotation causes storm to spin
  

state 4 effects on the Bahamas due to Hurricane Dorian 2019

• 13000 homes destroyed

• 65 people died and some went missing

• lack of food, clean water and medical help

• loss of jobs due to lack of tourism

state 3 responses of Hurricane Dorian

• Red cross provided medical help, food, water and emotional support

• UK navy and cruise ships brought supplies and evacuated survivors

• Red cross did a cash for work scheme where they paid local people to rebuild infrastructure
