Dr Tolhurst was an extremely knowledgeable man, his work in the fire environment was will be greatly missed, very sad with his recent passing in October 2023.
Great content here from an expert - thank you. Be good to have a few more pixels than 240 though so you can read the graphs and see the videos / modelling much more clearly.
How about more volume, i've turned it up all the way and it's still too quiet. If i raise the volume of my speakers i am afraid the walls will blow out when i start another video.
Sound level very low. Even at max volume I had trouble hearing what was being said. Please re-master with increased volume and repost. This is relevant now in Jan 2020.
Great presentation! Its not just a "bushfire" it is a scientific event. Many many factors play a part. Old mate must have been second guessing his stay and defend plan. Hats off to him.
Effective Fire Breaks (Asset Protection Zones) - Effective Bushfire Hazard Reduction Burning Effective Property Preparation. This is how you avoid disaster. These academics have ruined our fire services and systems
I am astounded at some people complaining that "firies didnt protect their home" when they had clearly done nothing to prepare by removing rubbish and dead vegetation from immediately around the home , let alone mitigation measures such as roof mount redundant sprinkler system.
Seems to me that we can’t control the weather, we can’t do a whole lot about topography but we can do a lot about fuel load. Yes it’s fine to analyse the behaviour of big fires and to try and predict how far embers can and will travel to enable better planning but as we’ve seen, we can do precious little once a huge fire gets traction. Our best bet is to be diligent about keeping fuel loads low so that when fires happen they don’t get so huge. We’ll never stop them and they are a very necessary part of nature. Our choices are to help nature by managing our land or leave nature to itself and put up with the consequences.
The video recorded by Jim Baruta shows a fully developed fire storm, which roars through in about one minute. The rest of the fire is nowhere near the same level of intensity.
bladeuser101 the issue is that things have changed since they traditionally did that on a larger scale centuries ago. Air temperature, air moisture, type of fauna, density of fauna, buildings and I’m sure a whole lot more have changed in the past 20 years let alone 200
@@Dr_Footbrake yeh you have to pick the weather conditions right and do it before winter so the regrowth from the rains provides food for the animals, sometimes they do burn offs after winter and animals have no food for a much longer period. burn offs should be done depending on the weather conditions not on a white mans time table.

Really want to see more high quality information on bushfires. This was good content.

@Jack Silverman Thanks for that. :-)
Fascinating having an explanation of Jim Barota’s video. Thanks
A fascinating video, thanks for posting. It really shows how truely frightening that fire was.

The Greens don't let you clear foliage

Eucalyptus oil can be used as jet fuel, it has ten times the energy of TNT, so it does tend to explode if you look at the wrong way.
Eucalyptus trees fed the 2009 fires and most of 2020 as well. It's like a blowtorch.
These fires spread so quickly because of the wind and all the Eucalyptus trees. It wasn't the temperature per se. The trees self sustained the fires.

Watched a video on cultural burning very interesting
the indigenous people had the bush burning mastered we need to learn from them
