Default Lightning + tree = steam

These aren't photos of the lightning itself, but 12 images of a
tree near work after Thursday evening's thunderstorms.

A lightning strike had removed two long lengths of bark on
different sides of the tree, and a small patch near the ground
opposite the first two. More than a little wood had been ejected
too and thrown some distance: splinters up to five feet long were
scattered across the field for around a hundred feet as well as
shards of bark, many with characteristic fraying at the ends.

Various IT systems within 600 yards 'weren't at all happy' at this
event, though most were ok after a restart. My pc swore at me when
it started the next day, showed me a cmos setup screen and thought
it was 2001. I can't say I blame it.

The picture with the barbed wire shows some blackening of the wire,
also the "scar" ends at the barbed wire, suggesting the discharge
jumped to the earthed wire.


I saw a tree hit near where i live. The oak must have been 200 years
old before it was killed by a lightning strike.
