Yep, and that was only 30m across and didn't actually hit the
ground...

Where can I get one of those temporary windscreens, to be on the safe side?

That particular bit of knowledge made not 1oz of difference to the amount of
sleep I had, I got to bed around 2am, having finished the last of the nights
breakdowns, was woken again at about 3am, to go and fix another one, back to
bed for 4.30ish, then up at 7.

Had I had any spare sleep to lose, I don't think I would have lost any
worrying about the tom-tom being in the middle of a herd of cows, instead of
in lane2 of the motorway!!!

That same google translation of a single web site is doing the rounds,
I suspect it's one of those plausible-sounding nonsense stories.

Quote from the United States Geological Survey..........

"Question: What effect did this earthquake have on the rotation of the
earth? Answer: Richard Gross at JPL has modeled the coseismic effect on the
Earth's rotation of the December 26 earthquake in Indonesia by using the
PREM model for the elastic properties of the Earth and the Harvard
centroid-moment tensor solution for the source properties of the earthquake.
The result is:

change in length of day: -2.676 microseconds
polar motion excitation X : -0.670 milliarcseconds
polar motion excitation Y: 0.475 milliarcseconds

Since the length of the day can be measured with an accuracy of about 20
microseconds, this model predicts that the change in the length-of-day
caused by the earthquake is much too small to be observed. And, since the
location of the earthquake was near the equator, this model predicts that
the change in polar motion excitation is also rather small, being about 0.82
milliarcsecond in amplitude. Such a small change in polar motion excitation
will also be difficult to detect"
