Ionospheric Map - Global - an explanation please?

This is fascinating, however I don't understand enough about the science.
On 11th April when there were the large EQ's in Indonesia, the map colours over that area were the lightest grey (highest part of the chart). The map colours over Gakona (Alaska) comprised a very large bright yellow 'square' and at the centre a bright red blob. The lowest part of the chart.
There are variations on the types of chart one can access on that site - beyond my comprehension.

I also noted that all day on 11th and again today (12th) the LISS is black globally.

The induction magnetometer link is here: http://www.haarp.alaska.edu/cgi-bin/...disp-scmag.cgi for your information. Also http://www.haarpstatus.com/status.html may be useful for some people.

Any boffins out there able to explain the ionospheric map in very easy-to-understand terms please?

He hasn't that expertise TargeT, I've asked him. Have now gone to WeatherorNut, and Solarwatcher in Oz.
Thanks anyway
