Some of the firing duration times were up to 6 minutes. - very impressive light shows from 10 miles away at night.
We also wired the beams and columns of the test stands and the joints to determine the effects and distortions of the gimballing engines under dynamic loads.

I think it's Coordinated Universal (UTC) time on the USGS site. I'm only keeping track of the intervals between ground motion and also realize that there must be tremendous amount of ground motion below 2.5.

You can download all 5278 quakes from the last 7 days in a CSV, or several other formats for your own perusal.

For the M7.1 quake on the 6th, I was at Big Stump in Kings Canyon National Park for a night of observing with my 11" telescope. Before the sky got dark enough for good deep sky observing I entertained several groups of tourists with the Moon, Jupiter, some bright double stars, a couple bright star clusters, and the Ring Nebula. At 8:19 p.m., when the quake struck, I was looking at the Moon at 215x. My first thought was, "Why is the scope shaking when there is no wind?" Then I realized the ground under my feet was moving. I usually sit to observe, and I would have noticed the quake immediately. But this time I was standing and my own natural body sway covered up the quake at first. This shaking was longer than the quake on the 4th, maybe 30 to 40 seconds. BTW, this was the first quake I have experienced that was strong enough to also shake the Moon.
My wife told me the next day that the quake caused the water to slosh out both ends of our pool. I also noticed that the quake had opened one of the file drawers in my desk about two inches. We have a friend who lives in Ridgecrest. She let my wife know that she and her house were fine, but that the power was out and if it stayed out too long, she was going to go stay with her son in Bakersfield.

I suspect they had a few toppled items but nothing major. They have larger problems with the occasional major snow storm as they're located waaaaaaAAAaay up a problematic road in the middle of a forest clearing.

My office in the Loma Prieta quake. Note the red arrow pointing at my desk chair. You can see my Boy Scout heritage; I was prepared with a fire egress ladder for out that third story window. (Too bad the ladder was only 2 stories..)

That's a real mess. BTW, my uncle and my cousin's husband were at Candlestick when Loma Prieta hit. It took them about 8 hours to get home to Mountain View. Both their houses were fine, but some books and knick-knacks tumbled from shelves, cabinet doors opened, etc.
Earlier on the 6th, after cleaning the filter elements, I had filled to pool to within 3" of the lip, so that helped the water escape. Our pool is a standard kidney shaped pool (about 32'x16'x8' deep max) and is oriented east-west. My distance to the epicenter is about 150 miles and my azimuth is about 120°.
