1: What timeframe, and what distance?

2: Using Rhode Island's area, 5.89 J/kg for moderate tornado instability, and 8000 m for cloud height, I give you 1.2845e+17 Joules, or 30.7 Megatons of TNT.

3. "Mountain sized" Okay, so at minimum a radius of 610 meters (assuming 45 degree slope, also its height)

I'll include a mid-end of 1000 meters (a bit larger) and a high end of 2000 meters (a pretty decent-sized mountain)

Low-End: 2.3769e+14 cc * 0.825 J/cc (for violent fragmentation of ice) = 1.9609e+14 Joules, or 46.87 Kilotons of TNT

Mid-End: 1.0472e+15 cc * 0.825 J/cc = 8.6394e+14 Joules, or 206.49 Kilotons of TNT

High-End: 8.3776e+15 cc * 0.825 J/cc = 6.9115e+15 Joules, or 1.65 Megatons of TNT

1)what you mean by distance?for timeframe about 3 seconds

2)so city level right?

3)so town,large town and city for the 3 cases?
