I've just improved the way that Catfood Earth displays earthquakes:
The biggest change is that you can choose to display a description for each quake. The description includes the magnitude, location, date and time.
There is also now a transparency range so that recent quakes are highlighted and then fade over time. The start and end of the range is fully configurable.
Lastly you can now set a minimum magnitude so that the display isn't cluttered with numerous minor quakes.
