This mornings tremor shook me out of my sleep. Now I can safely say I've experienced a mild earthquake and it left me slightly queasy.
Judging by the number of earthquakes this year versus other years, e.g. 2009, it's hard to say if its been a more active year or not even though in my mind it feels like it has.
It would be interesting to see if there are any patterns via spatial and temporal autocorrelations - I'm familiar with autocorrelations in time series, less so spatial and don't even know if we can combine both.
