Why was Cyclone Tracy called Tracy?
Cyclone Tracy has been described as the most significant tropical cyclone in Australia’s history and it changed how we viewed the threat of tropical cyclones to northern Australia. The following day the Tropical Cyclone Warning Centre in Darwin issued a warning that a cyclone had formed and gave it the name Tracy.
How many houses did Cyclone Tracy destroy?
It destroyed more than 70 percent of Darwin’s buildings, including 80 percent of houses. It left more than 25,000 out of the 47,000 inhabitants of the city homeless prior to landfall and required the evacuation of over 30,000 people, of whom many never returned.
What was the size of Cyclone Tracy?
about 50 km
By world standards, Tracy was a small but intense tropical cyclone at landfall, the radius of gale force winds being only about 50 km. The anemometer at Darwin Airport recorded a gust of 217 km/h before the instrument was destroyed. Tracy was first detected as a depression in the Arafura Sea on 20 December 1974.
How long did Cyclone Tracy last?
December 21, 1974 – December 26, 1974
What is the strongest cyclone to hit Australia?
Cyclone Mahina was the deadliest tropical cyclone in Australia’s recorded history, and probably one of the most intense ever recorded.
How has Darwin recovered from Cyclone Tracy?
Cyclone Tracy, which hit Darwin in the small hours of Christmas Day 1974, killed 71 people and devastated 80 per cent of the city. On 28 February 1975 the Whitlam government established the Darwin Reconstruction Commission, which effectively rebuilt the city within three years.
How much did it cost to rebuild Darwin after Cyclone Tracy?
After the cyclone passed, approximately 60% of Darwin’s houses were destroyed beyond repair with only 6% considered immediately habitable. The estimated cost of the event is in the order of about $400-500 million (in 1974 dollars), which equates to between $2 billion and $4 billion in today’s money.
What changed after Cyclone Tracy?
What did we learn from Cyclone Tracy?
Tracy highlighted the need for improved emergency management, including the dissemination of warnings, preparedness and response. It showed clearly that longer- term resilience does not lie simply in improved engineering standards, but also in the psychological welfare of individuals in the impacted community.
Why was Cyclone Tracy so destructive?
The damaging impacts of Cyclone Tracy were the result of a ‘direct hit’ on Darwin. Damage to buildings was worsened because Tracy was a slow moving storm resulting in extended periods of exposure to high winds. The community, government and emergency management team did very little to prepare for Cyclone Tracy.
Has there ever been a Category 5 cyclone?
They are by definition the strongest tropical cyclones that can form on Earth. The earliest tropical cyclone to be classified as a Category 5 severe tropical cyclone was Pam which was classified as a Category 5 between February 3 – 5, 1974, as it moved through the Coral Sea.
What was the most powerful storm on Earth?
The JTWC’s unofficial estimate of one-minute sustained winds of 305 km/h (190 mph) would, by that measure, make Haiyan the most powerful storm ever recorded to strike land. This record was later broken by Typhoon Goni in 2020.
