The fireball appears to be about seven feet in diameter (scaling off the Razor Crest). The 1 PSI radius (where windows will break) appears to be less than 20 feet, judging by the lack of effect on the surrounding rocks. Therefore, according to the Conventional Explosives
Effects Calculator (https://www.alternatewars.com/BBOW/Weapons/Conv_Explosive_Calculator.htm) the yield is less than 1-2 lbs of TNT (2-4 MJ).

The rock is clearly vaporized. Scaling off the ISD it is at least 0.4 meters in diameter, based on Brian Young's figures. Assuming it's solid iron it has a mass of 503.68 kg and requires
7.63 x 503.68 = 3840 MJ to vaporize. If the vaporization occurs within 1/15 of a second, the power of the bolt is roughly 57600 MW.
Remember that these figures are conservative, and apply only to light turbolasers in a shrunken SW (RW heavy turbos). Some have claimed (http://picard578.6te.net/startrek-vs-starwars/star_wars/space/starship_tactical_systems/turbolasers.html) that the bolts came from heavy turbolasers, by showing that the tiny guns we saw on the Death Star couldn't have fired them. However, those tiny guns are not turbolasers! All bolts actually identified as turbolasers have been several meters wide, as opposed to less than a foot for those guns. They're point-defense guns. The massive turrets on the top of an ISD are heavy turbos. The ones so comparatively small we can't normally see them are light or medium ones.

I'll assume the smaller ship (Tantive IV) is 7 feet long. The radius of the biggest blast is about 2 feet, so the explosive yield of the bolt is (very roughly) 10g minimum (or 41840 joules). [1]
Confidence in figure: 5/10
Okay, you don't like that answer. I'll try again, using the vaporization of the Tantive IV's armor (not melting, as we see vapor). The energy required to vaporize 1 kg of iron is about 763000 joules [2]—almost as powerful as turbolasers get.
Confidence in figure: 7/10

According to a Wiki page [1], a heavy turbolaser bolt has the explosive power of 250g of TNT. 250g of TNT equals 1046000 joules. [2] The energy required to melt 25g of ice at its freezing point is 8290 joules. [3] So a heavy turbolaser shot could melt 2.5 kg of ice.
To melt and vaporize iron takes about 7.63 megajoules per kg of iron. [4] So our turbolasers can vaporize roughly 137g of iron per shot.

This thread is a place to put your calculations for turbolaser yields, energy, or power.
