Community Reports


Perth , Western Australia

The Perth region is subject to a range of meteorologically related hazards including winter storms, summer storms, floods, tropical cyclones, heatwaves and bushfires. Of these, cool-season storms are the most frequent event and, on average, have the greatest economic impact.


Southeast Queensland

There is little doubt that tropical cyclones pose a significant threat to the urban communities of southeast Queensland. These spectacular meteorological phenomena are very large and have the potential to bring severe losses to the whole region.


Cairns

Since Cairns was founded in 1876 there have been at least 53 cyclones which have had a reported or measured impact on the city. One of the first, on 8 March 1878, almost destroyed the settlement before it had a chance to fully establish.


Mackay

There have been at least 77 cyclones which have had an impact on Mackay since the settlement was founded in 1862. The most significant impact was caused by a cyclone on 21 January 1918 in which the combined effects of strong winds, storm tide and flood resulted in the death of 30 people and destruction of, or damage to around 75 per cent of the town's buildings.


Gladstone

The Community Risk in Gladstone report considers tropical cyclones along with severe wind and storm tide as well as earthquakes.


Fieldwork

Severe tropical cyclone Larry crossed the far north Queensland coast near Etty Bay around 7:00 am on 20 March, 2006. It then tracked west-northwest and passed directly over the town of Innisfail. Within 48 hours teams from Geoscience Australia were on the ground to begin a program of assessing building and crop damage. The assessment continued for three weeks.


Risk modelling reports

The modelling of severe wind gust is a fundamental part of any wind hazard assessment. Statistical modelling is used for the most part to describe the probability of extreme wind occurrences.


AusGeo News

Tropical cyclone Larry was classified as a 'midget' cyclone due to the limited range of its destructive winds and the reduced exposure of coastal communities to cyclonic winds and airborne debris. This occurred because the cyclone moved relatively quickly after making landfall.

On Christmas Day 1974, Cyclone Tracy devastated Darwin with winds gusting to 237km/h. The cyclone resulted in the deaths of 71 people, including six lost at sea, and, according to the Insurance Disaster Response Organisation, caused more than A$837 million dollars damage.


N H (Doc) Fisher Geoscience Library

The N H (Doc) Fisher Geoscience Library at Geoscience Australia is the premier geoscience library in Australia. Established in 1946, the library, which is open to the public, has an extensive collection of earth sciences material.
