I have my bike up on its center stand for its major maintenance with all its parts around it. I was not too excited after the movement stopped, but promptly slung some safety straps to the ceiling joists and moved the important pieces out of harm's way.
I'm pretty sure a big one would topple it off the center stand, but maybe not off the side stand. I could be wrong though, so I'm also curious...

It did not wake me up, but is not unexpected. I follow this earthquake forecasting site. Works as well as weather prediction.
http://www.quakeprediction.com/San Francisco Earthquake Forecast.html
They forecasted a high probability of a quake for today, and hit it on the "head". What they are still working on making more accurate is the strength of the quakes.
Overall, the North Bay Area "Northlands" (M/C slang) is at risk for a very very big quake. I recently watched a news video that used a brick sitting on a large sheet of sand paper. The brick had a bungee-cord attached to it. The woman Doctor was pulling on the cord and said that pressure builds up and eventually the brick slides. Small slides are good. Big slides are bad. Our "bungee cord" for the Northlands is stretched more then spandex shorts on Fat Albert. LOL We should be having a quake every 30 years on the Rodger's Creek Fault, it's been 54. The Napa quake of 2014 was a different fault, so it did not release any pressure on the Rogers Creek Fault.
Tick - tick - tick

I started riding the year after 89. But yes the big one on the Hayward fault is coming and is overdue. All of these local small jolts lines right up with the what was happening the year or two before 89. No one can be sure but I wouldn't be surprised if it happens in the next few years.
Just don't be riding on a bridge when it happens. :teeth
More important than your bike, do you have food and water for 10+ days for you and your family in your home. That's what really matters.

Is there a minimum threshold that most dwellings built around here are able to withstand or does it highly vary based on when the dwellings were built?
Just curious if there's been a minimum standard that construction over the last X years has to withstand a Y magnitude earthquake or if it's not that black and white?

Cool simple map. Shows the Bay Area as having few quakes in the last 80 years.

Single story homes built after 1950 should withstand all quakes.
Heavy homes will suffer more structural damage. Homes are loosely rated as this:
Heavy = 2 story stucco walls with tile roof built after 1960 (meaning stucco is held off the ground. Also Cinder block walls.
Medium = 1-2 story stucco, no tile roof.
Light = 1 story, non stucco OR older home pre-1960 where stucco goes into the ground, no tile roof.
Weak points are garages with 6 to 18 inch walls on the sides of the garage door that have not been reinforced. There are several ways to reinforce them that don't cost more then $1000 with labor. Other weak points are walls with large windows or many windows. Hill side homes in step foundations that don't have plywood sheer walls under the house on the foundation wall. Also homes that have been remodeled without engineering to create large open floor plans. Now weak homes are very unlikely to "pancake" but could twist 2 inches+ leaving them non-repairable thus they will be torn-down. One last weak point are old chimneys.
The safest place in the house is a hallway. DO NOT GO UNDER A TABLE - GET AWAY FROM FURNITURE AND WINDOWS. Sit down in the hall and brace your feet on one side and your back on the other.

Here is a thread I wrote ten years ago.
"So, you have frame savers, but what about earthquake protection in your garage?"
www.bayarearidersforum.com/forums/showthread.php?t=238951
I have since moved on from ropes to bolting down a front wheel chock. I think it even comes with holes pre drilled for mounting down.

y'all worry too much. Been thru many including Loma Prieta (89') & the 6.9 in Livermore in 83' (?.)
Was in Candlestick for the World Series, was worried sick about the bikes but came home to find both still up on the swing arm stands. Same w/the Livermore quake (I was IN Livermore, wow! That was huge a mile f/epicenter.)
House had some damage in Loma Prieta (fireplace bricks fell out, crack along foundation, a few pics fell off walls, & books off shelves.) But nothing to write home about. Handyman bud fixed fireplace, & I fixed foundation...no biggie.
You live here; don't worry about it. As the East of the US is frozen right now, & they get tornadoes, hurricanes, & all kinds of crap. Compared to quakes, we got it made in the shade....:thumbup

I was working at SFO when the Loma Prieta quake hit. Luckily I had the bike. Had to lane split from SFO all the way to Hayward. And it was simply the BEST time lane splitting I've ever had. EVERY car pulled over and made room for all us riders. It was super nice. Of course, a week later and they're back to cutting me off and cussing at me.

Exactly Dave.
I came home from Ft. Bragg NC after the Loma Prieta hit and got to watch the series from home vs back east.:teeth
I was in So Cal during the Arrowhead, and Northridge quakes both 7 pointers.
Northridge had me flying rescue missions for days after it hit.
Its no biggie compared to Tornados, Crockygators on the highway, and Hurkyrains. Some of you might be scared into going home .. if memory serves me lots of easterners left in droves.
But really people it will be ok

The problem with 89 is that it gave us a false sense of security. Keep in mind two big factors: intensity and distance. The Hayward fault is much closer than 89 where the epicenter was 100 miles away near Santa Cruz and was on a different fault line. Also, 89 was only a 6.9 where as the next big is likely to be much bigger.
So sure, it could be a none event but it is also quite likely to be on the scale of 1906 and on a more vulnerable fault because of all of the construction that has happened on East Bay landfill since 1908. If you live in the flats, lookout. There is a reason that property is cheaper.
The upside is rent and property values will drop as they always do after a big earthquake. :thumbup

My condo is in a liquifaction zone, built on sand, so my upstairs condo becomes a ground-floor one if the quake gets bad enough. If the motos don't fall over it will be ok though. 
Probably a good time to double check the insurance.
The point of this thread was to ask how motos faired in 1989. So not sure it needed to be moved to sink.
I had similar thoughts, side stand probably better than center stand, but was hoping for anyone who experienced to chime in, and some did, good to hear that stuff.
