Incomplete v2 juubi feat

What would you rank this:
Multi mountain
Island level
Multi island level
Small country level

Nobody cares apparently.

No less than multi-mountain, I can't tell via eyeballing if it falls into practical small country level or beyond. It is certainly the greatest destructive feat in the HST at the moment, without doubt.

Based on the curvature of the earth.

The blast diameter is roughly a third of that length, so around 85 km diameter blast radius or 50 miles, add or take 5%. Or a blast area of 22 700 km² (or 8 800 square miles).

Never-mind, I forgot to convert the diameter to radius. It's 5 675 km² or 2 200 square miles. So it's city-scaled.

Meh, let's do this throughly.

x = 6371∙2tan(20/503) = 506.907323 km. (Notice that we're using twice the angle.)

The blast covers roughly 1/3rd of the surface. Meaning that it's diameter is x/3, and the radius x/6.

The area the blast covers is circular, the area is therefore π∙(x/6)² = 22 423.5568 km² or 8 657.78368 square miles.

So the area, with four significant digits is 22 420 km² or 8 658 square miles.

Bejing is the largest city in the world, 16 801.25 km² or 6 487.00 square miles.

Well, that Bejing number is actually the Bejing metropolitan area which includes 2 counties. Metro-to-Metro comparison, New York City Metro is the largest city at 8,683 square miles.

Apparently they do.

In case you wonder why I used twice the angle.

The curved path from point A to B is the angle times the radius (in radians)

Also, I must have been on drugs yesterday because I made another ****ing mistake. It's supposed to be arctan(20/503) = 0.0397404974 ≠ tan(20/503) = 0.0397823986.

The actual values are thus.

((6371∙2∙0.0397404974)/6)²∙π = 22 376.3461 km² ≈ 22 380 km² or 8 639.55553 square miles ≈ 8 640 square miles, with four significant digits.
