Hi Darren,

A Tunguska sized blast would not result in profound effects on tree growth some 
distance away from the impact, which is what is claimed here.

But if a Tunguska were to occur over the British Isles, that would not be fun 
indeed for part of its inhabitants. Still the affected area would be smaller 
than the British Isles. The Tunguska devastation zone is roughly some 100-140 km 
wide (63-88 miles).
