Why Do Some Tectonic Hazards Develop Into Disasters

Question 1

What are the hazards of tectonic activity

Answer 1

Hazrads are physical events

Earthquakes, volcanic eruptions, tsunami

W each of these, they bring their own hazards e.g. Lahars,flooding

Question 2

What are the vulnerabilities of tectonic hazards

Answer 2

Location of population (is it on a coast, mountains)

Proximity

Poverty, education levels, pop density

Question 3

It is only a disaster when

Answer 3

A hazard interacts w a vulnerable pop

Question 4

What is the capacity to cope

Answer 4

Governance, developement, planning

Question 5

Disaster risk is going to increase if

Answer 5

Larger the hazard w a large vulnerability and a low capacity to cope is going to increases disaster risk

Question 6

Pressure and Release model

Answer 6

Root causes include lack of governance and development can lead to the dynamic factors of vulnerabity such as levels of education, healthcare, training and investment in emergency services can lead to unsafe conditions which can interact w hazards can lead to a disaster.

Question 7

Hazard profile- physical factors

Answer 7

Magnitude- energy released measured on moment magnitude scale, or the older scale richer scale, VEI- volcanoes only

Frequency- if it happens once every 2 yrs, people might be familiar and prepared for it and may not live in the area

Speed onset- how quickly it happens, is it hard to predict cuz this can have an impact on how people respond to it and would relate to capacity to cope

Predictability= can u say where it happens such a s volcanoes, u know that the eruption will happen at that volcano but u cat do that w an EQ

Question 8

How does the hazard profiles relate to each other?

Answer 8

The higher the magnitude, the bigger the speed onset , the more area of will cover, the longer the duration,the bigger the disaster

Predictability will be have an impact on the level of disaster

Question 9

Vulnerability and capacity to cope factor

Answer 9

Development= access to good quality of housing, education so they know what to do, good healthcare services to cope with disaster

Governance= political, economic, and adminstrive governance cuz there will have impact on things like land-use planning, where people can build, law enforcement codes, are people obliged to build safe, EQ proof buildings, is protection built into infrastructure
, do they have a well trained response

Question 10

Geographical factors

Answer 10

Pop density

Isolation and accessibility= difficult to access mountain regions

Urbanisation= large slum settlement are badly designed, difficult for buildings to withstand
