A couple of recent UK Midlands earthquakes near Loughborough, Leicestershire. The main shock, magnitude 2.9 (above) occurred at 05:20:44 on January 18 and a magnitude 1.3 aftershock (below) at 11:40:04 on January 21, 2013. The first event was widely felt over a 25km radius, with some reports over 50km away.

At 13km depth these are natural earthquakes (with no added fracking involvement). Whilst I am loathed to ascribe UK intraplate seismicity to particular tectonic features, these events would approximately accord with the north eastern margin of the Midlands Microcraton.
