Magnitude of earthquake
Causes of earthquake
- The collision of the Indian plate into the Eurasian plate
- The Indian plate is converging with Eurasian at a rate of 45 mm/yr driving the uplift of the Himalayan mountain range
- 8,000 dead and 19,000 injured
- Highest loss of life in Kathmandu, due to its dense population and the number of buildings, which collapsed during the quake and after-shocks.
- Avalanches triggered by the quake killed and injured mountaineers on Mount Everest.
- 1.7 million children made homeless
- The steep valleys of the area suffered many landslides, the village of Ghodatabela was covered killing 250 people
- Nepal will lose $600 million in 2015-2017 climbing season
- People had to sleep outside due to aftershocks or houses collapsing
- Centuries-old buildings were destroyed at UNESCO World Heritage sites such as Dharahara Tower
- Economic losses at 35 percent of Nepal's GDP
- Heavy rain and cold night-time temperatures put those without shelter at greater risk from illness and disease
Management / lack of preparation
- aid hampered by Nepal only having one international airport with a single runway.
- Responses were slow as access to remote areas was difficult
-GIS tool "Crisis mapping" was used to coordinate the response
-Surgeons and inflatable hospitals were used
- Many buildings are poorly constructed
- The Asian Development Bank provided $200 million.
- The UK gave £73 million
- The UK also provided 30 tonnes of humanitarian aid and 8 tonnes of equipment.
- The UK sent around 100 search and rescue responders, medical experts, and disaster and rescue experts
- 90 percent of soldiers from the Nepalese army mobilised to worst hit areas
What did international aid agencies do?
On May 1st international aid agencies like Doctors Without Borders and the Red Cross started medically evacuating the critically wounded by helicopter from outlying areas
Poor building quality
This is the number one cause of deaths in an earthquake. By improving this by making earthquake proof buildings you can make people who live in earthquake zones much safer.
What does the response to an earthquake mean?
The response to an earthquake means what the government, emergency services and aid organisations do in the hours, days and weeks following an earthquake
What does preparedness mean?
This means the things that can be done prior to an earthquake that make people safer so that when an earthquake happens the impacts aren't as bad
