It was one of the strongest tropical storms ever recorded
By 7 November, Haiyan was labelled a Category 5 storm (Saffir Simpson scale), with estimated wind speeds up to 314 km/hr.
Caused by a large depression (low pressure air) over the pacific ocean (ocean temperatures above 27degrees)
Primary effects
Storm surge: A 7.5 m wave reached the coast, and a 5 m surge hit Tacloban City.
floods were so powerful that bodies were washed out from graves
Tacloban City was by far the worst-hit area. Around 90% of all buildings were destroyed, trees were uprooted or flattened, debris covered the land, electricity supplies were cut and infrastructure and communications destroyed.
5 million people saw their homes destroyed or become uninhabitable
6340 fatalities (estimated), almost all were in Tacloban.
Secondary effects
Also incidents of looting – made worse because only 100 police out of 1300 reported for duty.
Amazingly, there were no major outbreaks of disease.
Immediate response
Response was coordinated by the World Health Organisation and the United Nations (UN), and by other non-governmental organisations (NGOs) such as the Red Cross and the DEC (Disasters Emergency Committee).
Five days after the typhoon first struck, residents still had no water or safe shelter.
The UN fundraising appeal totalled $788 million, and foreign nations donated $500 million (estimated damage topped $8billion)
Satellite images and thermal cameras being used. Social media such as Twitter and Google Person Finder helped people locate their friends and family members.
Long term response
Thousands signed up for ‘cash for work’ schemes, in which people are paid by charities to help rebuild the city.
Grants were made for local fishing businesses to buy new boats
Oxfam provided rice seed to farmers
Tourist resorts were slowly rebuilt
Improve satellite and computer monitoring to improve prediction in future.
Soft engineering schemes like creating mangrove plantations or tree plantations are being introduced to reduce the impact of waves and to provide windbreaks.
government has also worked to improve warning systems and emergency plans
