Instead of burying the stuff underground, load a bunch on the back of a truck and have at it.

On July 3, 292 Iraqis lost their lives in ISIS’ deadliest attack thus far.
In a crowded street in Baghdad’s Karrada neighbourhood, a vehicle-borne improvised explosive device (VBIED) was detonated after midnight, causing nearby dwellings to be engulfed in flames.
Many residents were trapped inside the inferno and burned to death — it was estimated that merely 20 to 30 people had perished from the initial explosion.
But investigators at the scene are now concerned with another potential threat: A new type of bomb may have been developed and used by the terrorist group.
“We’ve never seen it before, and it’s very worrying,” a Western security source in Baghdad told the BBC.
So far, investigators have determined that the type of explosives and the way the chemicals were assembled in the van differed from the traditional methods inside the war-torn country.
This may explain how the explosion from the VBIED had left no distinctive crater, and that the impact from the initial explosion left buildings in the neighbourhood still intact.
Explosive experts explained to the BBC that the chemical composition was unique and that it was difficult to make.

Instead of burying the stuff underground, load a bunch on the back of a truck and have at it.
And the scary thing is that it doesn’t take a lot of technology to build a thermobaric bomb. I worry that some ISIS-inspired and/or trained terrorist will build a thermobaric bomb, put it on the back of a pickup truck, crash it through one of the entrances to an enclosed shopping mall and then detonate the bomb. The resulting explosion in such a confined space could kill several hundred people almost instantly from the quick oxygen depravation effect of the bomb going off.
The old engineer described it to me as homemade napalm.
Time has removed the actual contents from my mind, but it was readily available to the Sappers.
The experiments led to a particularly promising arrangement: a forty-gallon steel drum[nb 2] buried in an earthen bank with just the round front end exposed. At the back of the drum was an explosive which, when triggered, ruptured the drum and shot a jet of flame about 10 feet (3.0 m) wide and 30 yards (27 m) long.[1] The design was reminiscent of a weapon dating from late medieval times called a fougasse: a hollow in which was placed a barrel of gunpowder covered by rocks, the explosives to be detonated by a fuse at an opportune moment....
Experiments with the flame fougasse continued and it rapidly evolved. The fuel mixture was at first 40% petrol and 60% gas-oil, a mixture calculated to be useless as a vehicle fuel. A concoction of tar, lime, and petrol gel known as 5B was also developed. “5B was dark coloured, sticky, smooth paste which burned fiercely for many minutes, stuck easily to anything with which it came in contact and did not flow on burning.”[10] Early flame fougasse designs had a complex arrangement of explosive charges: a small one at the front to ignite the fuel and a main charge at the back to throw the fuel forward.[10][17] An important discovery was that including magnesium alloy turnings (the waste product of machining magnesium pieces in a lathe) with the main charge at the rear of the barrel would give reliable ignition. This eliminated the need for a separate ignition charge and its associated wiring.[10][18] The alloy of about 90% magnesium and 10% aluminium was, at the time, known under the trade name Elektron.

Ping. FAE?
Naw it’s just a clock.
Muslims haven’t created anything new in centuries.
Not really ‘new’ per se but definitely a new development for ISIS.
The varsity team has definitely graduated. This is oceans ahead of their usual IED’s; this requires serious skill in chemistry and engineering not just to go off in your face but to actually work right. They’ve got someone on their team by force or flattery or financing who can do this once and probably again. Worrying.
If there is no crater and the buildings are intact, that indicates there was no shockwave, which rules out high explosives. Maybe they used a small explosion to atomize flammable gas and then ignited it?
I don’t understand the purpose of your post
Possible ..... lots of US munitions and ordnance left behind that ISIS captured . Rig a truck load of 100 pound propane tanks with 125 gpf flex linear shape charges set up in series would be a hell of a fireball if set off in a open market or worse, streets surrounded by tall buildings etc ... Flex the pressured up tanks open in a market place filled with vendors that have open flame cooking in progress that gives up massive ignition at the outside of the cloud of fuel as well as ignition from the source side of the cloud of fuel....
Haven’t seen this specific incident but ask if the buildings burned or just a lot of dead from a overpressure event. Sort of a napalm versus FAE blast that would scorch versus long duration fire / burning ?
Stay safe !
This is not difficult. If it’s “new” a muslim didn’t make it.
The 55 gal drums did not have easily-removable lids so we wrapped det-cord around them near the top. Used it to cut the tops off and to be the igniter. Worked quite well to burn a few hundred sq meters of desert scrub and sand.
One of the hardest parts was convincing the task force motor pool WO2 to give up the barrels as he was already short on them from handing over a bunch to supply to make the crappers.
Kerosene and liquid soap or liquid detergent.
OK. I had only ever seen the French spelling.
They note the arrangement in the van/vehicle. It could be as simple as plumbing from the hardware store used to rapidly release a flammable gas in every direction (under, around and above) from a pressure vessel. Purely off the shelf items, there is a problem to overcome, but I’ll stop there.
If they just sprayed the gas around, it seems to me they’d just get a little fireball... that’s why I’m thinking they atomized it. Works better in a closed space, but it will still work even in the open air.
Fougasse in French cuisine is a type of hearth bread originally used to assess the temperature of a wood fired oven. It is found in Provence and is the French equivalent of a Calzone. The name has the same Latin roots as modern Italian Focaccia bread.
Fougasse is not otherwise a word in French, though it sounds like it might be. Fou means 'crazy' or 'mad'. 'Gasse' sounds like 'gas' in English but 'gas' in French is gaz.
Fougasse and fougade both mean a type of buried mine but I cannot find any reference to word origin in either English or French.

Thanks for the additional information. I was going by the 1971 Oxford English Dictionary, which does say that the word is an alteration of “fougade” but gives no other derivation.
There is an OED entry for the obsolete 17th-century word “fougue” or “fogue”, meaning fury, passion, ardor, or impetuosity, and derived from the French word “fougue” which my French-English dictionary defines as spirit or ardor.
So I think you could put together a plausible connection between the word “fougue” and either meaning of “fougasse”, bomb or bread.
I have to stop now, or Slings and Arrows will demand that I take a drink for trying to hijack this thread.
Take one anyway, you look a little dehydrated.
