Had an earthquake today. Noticeable shaking of windows and ceiling, just for a couple of seconds, but enough to make you start wondering what the bloody hell's going on and whether you need to take emergency action. I've never experienced anything like it. It was logged at 1237 local time and at the epicentre was strength 4.3: http://www.volcanodiscovery.com/earthquakes/quake-info/689940/M4.3-Sat-31-May-3km-NE-of-Skalna-Czech-Republic.html
