T-japan 2011
T- indian ocean in Thailand (Boxing Day) 2004
what are the 3 disaster trends overtime?
name all 3) or (name and explain one
- deaths have fallen over time because of better response management
- number of reported disasters have increased because of better technology and development of countries
- number of people affected by disasters have increased because population has increased and more people are living in risky areas
what are the tectonic disaster trends overtime?
- no change in the number oh earthquake disasters
- earthquake economic loss is increasing
- economic loss from disasters is increasing
- volcanic disasters are much less frequent
what happened in the volcanic event of mount Pinatubo in (1991)?
- erupted a ash and sulphur dioxide cloud
- ash deposited in the indian ocean
- satellite tracked the movement of ash
who was effected in the volcanic event of mount Pinatubo in (1991)?
aeroplanes west of the philippines ($100 million damage )
what were the global impacts of the volcanic event of mount Pinatubo in (1991)? (name one)
- SO2 aerosol cloud
- spread and circled around the world
- global decrease in the temperature of about 0.6 degrees
what happened in the volcanic event of the Iceland mountain in 2010?
- erupted 110 million m3 of ash in one week
- prevailing winds extend
who was effected in the volcanic event of the Iceland mountain in 2010?
- distribution across main flight paths and airports
- tourism distributed
- workers
what were the global impacts of the volcanic event of the Iceland mountain in 2010?
- airlines lost $200 million
- music bands couldn’t get to California
- car parts didn’t reach european factories
- sports teams having to travel by coach rather then aeroplane
what happened in the 2011 tohoku Tsunami in Japan?
tsunami around the pacific ocean with waves as high as 2m in Chile

countries around the indian oceans e.g. india, Thailand
what were the global impacts of the 2004 indian ocean tsunami?
- deaths in Indonesia, Thailand, sri lanka and india
- ports destroyed - trade also destroyed
what are the three stages of the hazard management cycle?
pre-disaster
response
post-disaster
what is the hazard management cycle?
a prediction when possible of attempts to manage the impacts of natural disasters
what is part of the pre disaster stage of the hazard management cycle? name one
risk assessment
mitigation/prevention
preparedness
what is part of the response stage of the hazard management cycle? name one
warning/evacuation
saving people
providing immediate assistance
assessing damage
what is part of the post-disaster stage of the hazard management cycle? name one
risk assessment/prevention
ongoing development activities
economic and social recovery
reconstruction
what is Parks disaster response curve?
can be used to help plan and understand risk and resilience as well at to better prepare for future events
what is the swish cheese model?
is disaster is thought to occur as a result of a series of coincidental events and processes
> reduce no.of holes = no. of systematic weakness
reduce size of the holes= scale of system weakness
what are the three modifications you can use to modify a disaster?
modify the event
modify vulnerability
modify loss
what are the 4 ways to modify a tectonic event?
land-se zoning
aseismic buildings
tsunami defences
lava diversions
