keeping an eye on things

You can now keep an eye on my probability for shaking.

That's right. This map, much like a weather map, shows predictions for earthquakes.

According to the site though, it's not very useful:
The primary use of this map is educational. Watching the fluctuations in the probabilities will help you understand the nature of earthquake clustering and how the patterns change with time. [...] The only time that the probabilities become large enough to affect you is after a significant earthquake that may have already caused damage. You already knew that aftershocks are likely in this situation. The map is showing you where those aftershocks are most likely to be felt and how the risk changes with time.

Thanks gov, that's really reassuring.
