Trends In Tectonic Disasters

Question 1

TRUE or FALSE: have the total number of disasters fallen since 1969

Answer 1

FALSE
the number of reported natural hazards have risen

Question 2

What is the reasoning for more tectonic disasters

Answer 2

Improvements monitoring and recording events

Improvements in communication technology - allows more news events to be reported

Global population has risen - more people occupying hazardous space

Question 3

Has the number of deaths per tectonic disaster increased or decreased overtime

Answer 3

Decreased
However the number of people affected by disasters has risen

Question 4

what is the reason for why the number of people impacted by tectonic disasters has increased

Answer 4

Rise in global population, therefore more people now occupy hazardous space and some areas that were inhibited are no being developed and built up.

for example Coastal cities - exposed to hurricanes
and Housing developed on river flood plains

1960 popu - 3 billion
2016 popu - 7.3 billion

Question 5

true or false economic cost associated with tectonic disasters decreased?

Answer 5

FALSE
the financial cost of disaster is rising.

Question 6

how much has the cost of tectonic disasters risen since the 1990s

Answer 6

1990s, the economic cost averaged US$20 billion per year. Increased to US$100 billion per year between 2000 and 2010.

Question 7

why is data about tectonic disasters not always the most accurate/reliable

Answer 7

the collection of disaster data is often incomplete or inaccurate due to:

• the immediate focus being organising aid and rescues not collecting data
  -no single organisation is responsible for data collection so a variety of methods used
  -differences in definitions of some key terms/categories such as ‘disaster’ or ‘damage’
  -difficult to collect data from remote locations – leads to an underreporting of death/damage which are area which are in need of help the most
