Q

Nepals economic development presents serveral challenges that impact its ability to manage earthquakes efficiently- what are the 5 reasons why

A
  1. Limited financial resources- on the most least developed countries with a low GDP per capita. Limited financial capacity for the government to invest in robust earthquake preparedness
  2. Weak infrastructure- critically underdeveloped, lack of paved roads and reliable transportation routes hampers delivery of aid to remote areas.
  3. Political instability- decade long civil war ending in 2006, hindered long term planning of disaster management policies.
  4. Economic impacts of earthquakes- 2015 ghorka earthquake estimated $7 billion
  5. Poverty and vulnerability- poorer communities reside in substandard housing more likely to collapse, limited access to education and resources means that their community preparedness is low.

Q

Give a brief summary of nepals tectonic structure

A

Type- convergent plate boundary
Plates involved- Indian plate and Eurasian plate
Movement- Indian plate moving northwards at a rate of 40-50mm per year
Formation of the Himalayas- Himalayas rise by 1cm per year due to the movement upwards from the plates

Q

How does Nepal modify the event of an earthquake

A
  • no preventing or modifying the primary earthquake event
  • secondary hazards such as landslides can be modified against
  • deforestation reduces slope stability so afforestation operates on a high level nationally in Nepal
  • 1992 forest act has caused forest cover to double

Q

How does Nepal modify vulnerability of earthquakes

A

1988 earthquake- several disasters mitigation implemented by NGOS (NSET)
NSET- “earthquake safe communities in Nepal by 2020” school safety programme
80% new buildings built informally- NSET raises awareness of affordable construction techniques
