Case Study - Gorkha Earthquake
Himalayas
April 2015
Causes:
- magnitude 7.9
- happened 90 km north-east of Kathmandu, in the middle of the collision zone where the Indo-Australian plate meets the Eurasian plate.
- the geological structure of valleys in Nepal increases the risk of earthquakes (pre-historic lakes filled many of the valleys so the sediment is soft)
- the depth of soft sediment reaches 600m deep in the Kathmandu valley → seismic waves that pass through this material are amplified, causing structures to swing violently
Impacts:
- 9,000 deaths and 22,000 injured
- Economic losses amounted to US$5 billion
- There were many landslides down the steep mountain slopes with killer snow and ice avalanches triggered on Mt. Everest (killed 20 people)
- Many rural villages were totally destroyed – over 450,000 houses were damaged
- More than 2.8 million people were displaced from the Kathmandu Valley, and there was an increase in the trafficking of homeless girls into the sex trade in South Asia
\
Aid:
- An estimated 1 million people needed emergency food assistance
- The Asian Development Bank provided US$200 million of aid for reconstruction
- Locations high in the Himalayan Mountains could not be accessed for many days and relief aid was slow arriving
- There was severe gender discrimination in the receipt of aid with thousands of women going without
\
Geopolitics
- Nepalese government aid was hindered by political turmoil before and after the event
- More geopolitical issues arose as neighbouring countries (e.g. India and Indonesia) competed with each other for greater influence within Nepal
