This one was reported as being a really sharp jolt. One person said it felt like his house was hit by a truck that rammed his house.
What is the scariest, is the aftershocks because your nerves are so frayed from the initial quake.
In 89', I had earthquake dreams for months afterwards. I was 5 miles from the epicenter then. Now I'm 3 miles from the fault line of the Hayward fault.
