It appears Google Earth received a huge update last night (see Google Earth blog). Large areas in Russia, China, Africa, South America, Australia, New Zealand etc. have now very high resolution aerial photos, even over rural and desert areas.

See for example the Tunguska Event location in Siberia (60°54'05" N, 101°53'46" E) if there is any fallen trees visible anymore...
