Yep - thats exactly where it is - Google Earth looking towards Maydena

It therefore appears to me that fuel reduction burns in the current fire locations has not been occuring to any significant extent.

Here is a case where a fuel reduction burn from 2017/2018 was not enough to pull up a wildfire

Yep. It hadn't reached that point when I drove out, but that area around Harlequin Shore had obviously been burnt fairly recently and this fire just went right over the top of it.

That burn was only a few years ago but its well documented that fires will do that.

Ah, I stand corrected. I didn't have the 'open bookmarks' icon showing up, but now that I click on the blank the bookmark list appears:

(but the bookmark isn't loading layers correctly currently for me either)

And the storm on Wednesday night has started at least one new one - just NE of Sculptured Mountain. The Serpentine Shore fire has hit over the top of Greycap and is burning up spurs very close to the tops of Cleft and Murphys.
Southern edge of Gell River has jumped the road, burnt most of the Needles and is heading for Mueller. So far the big one is sidling south around Bobs and sparing the King Billy forests and the summit cushion plants.

I’m hoping tas fire put a call out for help to flog this dam fire to dormancy as I’m finding it really hard watching this beast eat all my favourite places :cry:

Give me a wet Broom and I will thrash that dam smouldering beastie in submission, oh&s be dammed :D

Nice article in the Guardian

these fires signal a terrifying new reality, as disturbing and ultimately almost certainly as tragic as the coral reef bleaching of the Great Barrier Reef.

For how many 100's of years have we been having fires in Tasmania, and just now the fires are due to climate change?
Hmmm

It is not the fire itself but the increase in frequency and intensity of fire due to climate change. All else being equal the increase in temperature increases evaporation and so makes for a drier landscape more capable of supporting larger and more intense fires and over a longer "fire season". In the past these fires would still have occurred but the damper soils and vegetation would have limited their intensity and spread.

In a discussion with a former professor of forestry, he mentioned that the worst fires are usually in areas with high average rainfalls. These areas generate a lot of fuel, so if they do get unusually dry periods - enough for the fuel to dry out, then they have the potential to fuel greater fires.

The accumulation of vegetation litter is landscape specific. To generalise in such as a way is very unscientific as it disregards factors such as vegetation type and decomposition. Decomposition is often overlooked by those who would make such comments as high rainfall forests tend (a sensible generalisation) to get higher rates of decomposition therefore lower litter accumulations.

I tend not to use fuel or hazard in these discussions. It's similar to calling feral horses their emotive name - brumbies.

I followed this to a discussion of California's record spend on 'hazard reduction' including mechanical reduction and burn-offs.
Their state budget, just for hazard reduction, was several hundred million $.. and some measures are pretty extreme eg.groomed /thinned zones and dozer-ed firebreaks.

anything from 40-100mm over the next few days predicted as well, hopefully some good falls making it to the SW and Central Plateau :)

Lots of rain in SW and Central Plateau - just where it’s needed. As a result no hotspots since Wednesday:

Looking at the map MikeB even though some significant areas of the Tassie landscape have been affected, some very iconic areas could have been lost had the rain not come when it did and due the superb work of our firefighters. Also there was commentary on social media that the decline in forestry activity was to blame for these fires. Plenty of cleared coupes plantation and otherwise in the Riveaux Road fire.
