may happen
that the globe disappears from the screen. In that case, it is actually moved
away from the desktop area. If that occurs, find the file EQ3D.ini (possibly
Earthquake3D.ini) under C:\Windows and delete it. When Earthquake 3D is then
again started, this file is written anew.) There is also an “Extended Version”

A few websites earlier displayed animated graphics showing how radioactivity from Fukushima spreads with jet streams. They are no more there. Censored? One may, however, search under „Fukushima potential releases“ and the like in, e.g., Google. A lot of websites are found but all have OLD data from the spring 2011,.It appears quite obvious that we are not supposed to know the truth about this! Here is a regrettably rather old graphic representation (even though the website has a new date).
