The video below shows earthquakes of magnitude 2.5 or higher from November, 2010. Each quake fades over the course of a day (which lasts two seconds in the video).
I created this using Catfood Earth, saving an image every hour for the month of November. There is some minor flickering from frames with no data. It's amazing to watch how active the Earth really is. On my desktop I have the earthquakes layer set to magnitude 5.0+ so I only see larger quakes. When a really big quake happens I often see it on my desktop before it hits the news.
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.
Download the update from Catfood Earth Beta and leave a comment to let me know what you think.
I just released a small update to the Catfood Earth Beta adding a layer for earthquakes.
The layer uses the USGS feed for earthquakes over magnitude 2.5 in the past day.
Catfood Earth displays an accented circle over the epicenter of the earthquake. The size of the circle is proportional to the magnitude. You can customize the fill and accent colors. It's also possible to show earthquakes from the past hour up to the past 24 hours.
