I have to share with you an experience I just went through.
About an hour ago, while I was playing "Call of Duty 3" on my Xbox 360. Suddenly, as I was covering my teammates and taking severe enemy fire, I felt a strong shaking. "Damn", I said, "this force feedback controller has got a pretty strong kick". And then I've noticed that it's not just my hands that are shaking, it was the entire house.
I've been living in California for a little over a year now, but this was my first major earthquake - and it was scary as hell. The adrenaline still floats in my system. It lasted over 2 minutes and almost every thing that wasn't nailed down shook. Even when I stepped out, I was still wobbly.
I later verified that not only was this a strong quake (5.6 on the Richter scale), but it's epicenter was 5 miles (8Km) from me, in San Jose. Here's a link to "my quake" which the government named "event nc40204628" and categorized as a "moderate earthquake". I find the mere fact that there is a site that can show you those "events" in near-realtime quite frightening.
And I was told to expect aftershocks. Hope I can sleep tonight...
Update: seems like I'm not the only one who has experienced this earthquake.
