I'm about 60 miles away and it lasted maybe 10 seconds, a nice rolling wave. A friend only 40 miles away felt aftershocks. My brother in law, 120 miles away, felt it as "the most mellow earthquake of [his] life".
I don't think a 5.6 is enough to do real damage to a place that's built to stand earthquakes, but I'm curious what it was like in Chino anyway. Anyone there? I do hope everyone's alright.
