SYDNEY BUSHFIRES 1994

Introduction

My case study for a particular natural hazard is the Sydney Bushfires of 1994. From 27th December 1993, to 16th January 1994, NSW suffered a total of 800 destructive bushfires, most within 250km of Sydney. They ran from the coast of the Queensland border, to Bega and as far in as Bathurst. These fires attracted world wide coverage, as theoretically, Sydney had been surrounded by fires and all major highways leading to this city had been closed.

Processes

Around 90% of the total fires were started by arsons, the rest by lightning strikes. The fires spread at tremendous speeds due to the dry conditions, as no significant rainfall had been recorded in NSW. Humidity (10%) was low which also aided the fires. Also, copious amounts of dry leaves, which acted as fuel had built up since the last fire.  Strong winds up to 50km/h and extreme temperatures of around 30-40°C also accelerated the fires causing widespread damage in NSW.

Impacts

In terms of social impact, four people died as a result of the fire, two of whom were volunteer firefighters. Around 27, 250citizens had to be evacuated, and 205 homes were reduced to rubble along with 70 significantly damaged, most located in the Sutherland region. Clouds of smog shrouded NSW causing many respiratory sicknesses such as Asthma attacks.

The environment suffered drastically, with 800,000 hectare of land burnt from the fires, with the almost total annihilation of the Royal National Park. Large totals of wildlife such as koalas and reptiles perished, along with 200livestock.
