Hi Todd. I would have to agree with you in that Morgan Hill and Livermore are a far piece from one another, but the forecasted epicenter was 37.2N/121.6W. The quake occurred at 37.2N/121.6W. How much closer can you get?

As to this being a foreshock. I have no way of knowing that. We will just have to wait and see. Take Care…Don in creepy town
