Well the ground is a rumbling down there -

Anyone have a clue as to whether its geothermal activity or tectonic?

It did have another one a little further north - if it keeps migrating you just might get your 6.1 on the San Jacinto!

I had some vertigo episodes last night which is highly unusual for me... I haven't been feeling well this afternoon either - kinda under pressure. Odd sensation. Unless we have a high pressure system arriving - there's been so many lows going through here I've forgotten what the sun looks like! (well - for southern cal anyway)
