@fab_hinz Ok, I get 620 meters from there to center of explosions warehouse. Popping some formulas...
@fab_hinz If we call that 2-3 PSI there (concrete block perimeter wall partly collapsed) ... 3 PSI would give:
0.62 = y^0.33 x 1.0
y^0.33 = 0.62
y = .238 kilotons, about 240 tons TNT equivalent
0.62 = y^0.33 x 1.0
y^0.33 = 0.62
y = .238 kilotons, about 240 tons TNT equivalent
@fab_hinz If it’s 2 PSI then:
0.62 = y^0.33 x 1.5
y = 0.070 kt, about 70 tons TNT equivalent.
If we check 5 PSI as outside limit,
0.62 = y^0.33 x 0.71
y = 0.665 kt, 665 tons TNT equivalent
0.62 = y^0.33 x 1.5
y = 0.070 kt, about 70 tons TNT equivalent.
If we check 5 PSI as outside limit,
0.62 = y^0.33 x 0.71
y = 0.665 kt, 665 tons TNT equivalent
@fab_hinz Notes: see Nuclear Weapons FAQ section 5.6.2 Blast Damage or Injury nuclearweaponarchive.org/Nwfaq/Nfaq5.ht…
@fab_hinz The effects of 1 PSI blast overpressure break glass, roughly. Light structural damage and residential wood structures collapse around 3 PSI, reinforced concrete around 5 PSI. I will dig out Cooper’s “Explosives Engineering” for small explosions scale up effects approach later.
@fab_hinz But energy ranges of tens of tons and hundredof tons are fine in the NWFAQ and related nuclear rough modeling. I originally thought a kiloton plus, this is suggesting that’s a bit too high.
@fab_hinz We need a lot more locations data to cross check this though. Not a single point & calculation.
@fab_hinz Further geolocation.
That’s 1,300 meters from the explosion center and 1 PSI damage roughly. At exactly 1 PSI that would be 207 tons TNT equivalent. However, buildings in way / damage down to street level make models very imprecise.

@fab_hinz We’re working on a imagery of a 3,700 meter lightly shattered commercial glass window and other anecdotal reports further off. There’s a lot of damage. Doesn’t necessarily imply hugely much more energy though.
