5.b. There are various strategies to manage hazards from earthquake activity. Flashcards
How is Japan able to mitigate against earthquakes?
(Case study: Living with earthquakes – Japan)
High economic wealth.
Highly developed education system.
Stable political environment enable it to cope with the constant threat of high-magnitude earthquake events.
Japan has developed a high level of what?
(Mitigating the vulnerability)
(Case study: Living with earthquakes – Japan)
High level of preparedness to deal with earthquake hazards.
What is JMA responsible for?
(Research and monitoring)
(Mitigating the vulnerability)
(Case study: Living with earthquakes – Japan)
Providing information and warnings of impending earthquakes and tsunamis.
What lies at the heart of Japan’s mitigation strategies? What does this do?
(Research and monitoring)
(Mitigating the vulnerability)
(Case study: Living with earthquakes – Japan)
The Japan Meteorological Agency (JMA).
They mitigate against natural disasters, including earthquakes and tsunamis and extreme weather events such as typhoons.
Japan’s detailed disaster plan involves what? Give examples.
(Research and monitoring)
(Mitigating the vulnerability)
(Case study: Living with earthquakes – Japan)
Involves a wide range of organisations.
E.g. governments, medical services, fire, military, transport, power and telecommunications companies.
State 5 features of building design that help to mitigate against Japanese earthquake vulnerability.
(Buildings with aseismic design)
(Mitigating the vulnerability)
(Case study: Living with earthquakes – Japan)
E.g. steel frames and braces capable of moving without collapsing.
E.g. Rubber shock absorbers in foundations.
E.g. Very deep foundations into solid rock.
E.g. A ‘soft storey’ at the bottom of tall buildings such as a car park, which collapses, allowing upper floors to sink down on to it; counter-weights on roofs, which move during an earthquake.
E.g. Suspension bridges capable of movement rather than rigid cantilever design.
E.g. Flexible joints in underground utility pipes, e.g. gas and water.
State 5 general mitigation strategies used in Japan.
(Buildings with aseismic design)
(Mitigating the vulnerability)
(Case study: Living with earthquakes – Japan)
Fire proofing older wooden buildings, which are common in historic districts of Japanese cities.
Land-use zoning that provides for open spaces where people can assemble after an earthquake.
Controlling building in locations susceptible to excessive ground shaking or liquefaction.
Tsunami warning systems off the coast.
Refuge sites on permanent stand-by equipped with tents, bottled water, blankets.
Community preparedness - ongoing education and training for all ages.
Is Japan able to mitigate loss well? How?
(Mitigating the loss)
(Case study: Living with earthquakes – Japan)
Being one of the most advanced countries in the world, Japan has vast resources to manage short-term losses caused by earthquakes.
How does Japan often mitigate against loss? What is the aim?
(Mitigating the loss)
(Case study: Living with earthquakes – Japan)
Well-rehearsed recovery and reconstruction plans, at national, regional and local levels, can be actioned immediately following an earthquake, e.g. small villages, key infrastructure.
The aim is to rebuild physically, economically and socially as quickly as possible.
Recent earthquakes have caused Japan to do what?
(Conclusion)
(Case study: Living with earthquakes – Japan)
Reappraise how it manages the impacts of earthquakes and related hazards.
What was completed after the Kobe quake of 1995?
(Conclusion)
(Case study: Living with earthquakes – Japan)
Much work was undertaken re-strengthening structures such as bridges and roads that were previously thought to be safe from shaking.
What is Japan constantly doing to its mitigation strategies?
(Conclusion)
(Case study: Living with earthquakes – Japan)
Updating its exposure, vulnerability and loss.
Compare Japan’s (ACs) resilience to EDC and LIDC resilience.
(Conclusion)
(Case study: Living with earthquakes – Japan)
The country, industries, and businesses and families tend to have the resources that give them a high degree of resilience.
By contrast, EDCs and LIDCs have fewer resources and so their resilience is much less.
EDCs and LIDCs have a low level of resistance. What does this mean as a result?
(Conclusion)
(Case study: Living with earthquakes – Japan)
The impacts of earthquake disasters in the short term are more serious, and longer lasting.
Since 2010, the Haitian population has become very preoccupied by what?
(Case study: Living with earthquakes – Haiti)
By the risks posed by earthquakes in this multi-hazarded country.
However, there are significant obstacles in building systems that mitigate against the impacts of these tectonic hazards to reduce vulnerability and improve the capacity to cope.
