I had a weird experience today. I was awake but dozing around 5 am when I felt a tremor, in fact, 2 short tremors. An earthquake of sorts? I gather it is not uncommon to have tremors; apparently it is just that we don't notice them.
I noted the time 5:25 am and decided to Google a site which might show something in real time. Here it is:
The organisation which monitors tremors in the UK is the British Geological Survey. Their website is here and shows a graph in the section called Real-time Seismograms. As there was no key I assume a tremor is shown as blue. Well there was nothing at 5:25 am although it showed something at 5:15 am. So it's a mystery.
Nonetheless, if I make a note of it ... and if it happens again or is noted by other people in the area .... then perhaps a pattern might emerge which could lead to an explanation.
