There is nothing comparable that is
man-made. Explosives would merely result in devastation. Imagine
trying to mount, say, a whole village (just a village, not an entire
country!) on some kind of manufactured plate, then inventing some
device that could extert the energy needed to shift it like an
earthquake can. I don't think human beings could ever devise such a
device. Totally mind-boggling to me, that tremor last night.

The Brum one a few years ago, despite being further away and not as
big, seemed to be much stronger here. That one managed to wake me up
from a very deep sleep and gave me quite a start.

This one managed to wake me, but I was just at the dozing off stage so
I caught the whole thing. A quiet rumble initially which gradually
built up then just stopped.

I suppose the difference might have been the subterrainian rock strata
and the direction it lays in.

Probably my most startled moment from a natural phenomena whilst in a
deep sleep - was several years ago when the church steeple a 100 yds
away was severally damaged by a lightning strike. I actually think I
was so startled I lifted off the bed :-) The pulse from the strike
caused us quite a bit of damage to our electronics.
