User blog comment:EvanDude345rv5/Fairy Tail 362 Rant : WTF ? Happy surviving a nuke/@comment-4829046-20131129173042/@comment-5580383-20131129220142

Happy can fly thousands of feet high within seconds.

Also a nuke using has the radius of 1 to 10 km, which would enough to destroy a town and putting a nuke underground would caused the energy to shoot up and just obilierate the town via shockwaves and earthquakes.

Considering base Jackal's casual explosive's covered nearly a km in size alone and this suicide bomb is much larger, there's a good chance that digging underground won't help at all, if anything makes things worse.
