If you find the seismic event predictions alarming - a post to 
your wall or perhaps to those of friends, especially those who 
might be within the impact area. Clever programmers would 
find a way to let you save the predictions in a less numerate  
and more graphical form and perhaps even build a tinyURL 
which you could scoop up here. As with Tweets, we like the idea 
that an informal social network might be useful in warning of a 
disaster (as well as communicating urgent needs after it) but
we are wary of what will likely be over-burdened "pipes" being 
flooded with duplicate tweets, posts and so on.
