Typhoon Haiyan Case Study

Ever wondered what happens when nature unleashes its full fury? Typhoon Haiyan gives us a terrifying answer - this Category 5 super typhoon struck Southeast Asia in November 2015, starting as just a simple tropical depression before becoming a monster storm.

The numbers are absolutely mind-blowing. Haiyan packed 230 km/h sustained winds for 10 minutes straight, with peak gusts hitting an incredible 315 km/h for one minute. The storm surge - essentially a wall of seawater pushed inland - reached over 5 metres high, which is like having a two-storey building worth of water crashing onto the coast.

Primary effects hit immediately and were devastating. Over 6,300 people died, mainly from drowning or falling debris, whilst 30,000 fishing boats were completely destroyed. The coastal city of Tacloban was absolutely flattened - more than 90% of the city was destroyed by the 5-metre storm surge, with 40,000 homes wiped out and 60,000 people displaced.

Remember: Primary effects happen immediately during the disaster, whilst secondary effects develop over time afterwards.

The secondary effects created long-lasting problems across the region. Widespread flooding destroyed crops, affecting 14 million people overall. Disease outbreaks spread quickly, roads were blocked by landslides, and identifying bodies became so difficult that mass burials were necessary. Violence and looting broke out in Tacloban as 6 million people lost their income source.

Immediate responses came from around the world. The Philippines Red Cross had cleverly pre-positioned emergency supplies, whilst Canada and the USA deployed military aircraft for search and rescue operations. Over 1.1 million people received clean water from the Red Cross, and 1,200 evacuation centres provided shelter for the homeless.

Long-term responses focused on rebuilding better than before. The government launched a 'build back better' scheme, whilst the UNDP set up cash-for-work programmes that paid villagers to clear debris. Aid organisations helped replace the thousands of destroyed fishing boats, and massive vaccination programmes protected children from disease outbreaks.
