CA - 6.0 earthquake American Canyon

[LinasK]

It was a significant earthquake. I woke up out of a dead sleep. Felt like the roof of my house was being rolled back. It felt rolling like to me, not like the 1989 earthquake which I experienced as a 'sound', a huge jolt and building moving side to side and gaining momentum. Where I live, this quake didn't seem nearly as long as the 1989 quake. But I was closer to that epicenter so maybe that makes a difference. Had to turn on TV after I felt this one to see if we had just had a quake or was I dreaming.

NBCBayArea has been talking about it all day. 6.0 is TEN times larger than a 5.0. Also the nature of the geology in the area of the epicenter impacts the overall impact of the quake. When 'fill', soft mud, and 'sedimentary soil' are involved, it can increase damage. Also this was not on the San Andreas fault and yet it was felt throughout a similar area.

I.B.Nora, have you gotten any info as to what fault this was on? Just curious, thanks. I'm living directly on top of the Calaveras fault line.

Some wineries hit hard-barrels knocked off shelves etc. Napa appears to be hardest hit-Vallejo also-US Forest Service on Muir Island had a water break-reports still coming in

I'd expect that. They are only 6 mi. from the epicenter, on poor soil quality, lots of old buildings, and lots of glass wine bottles around.

It's the W. Napa Fault Zone-Brown Valley Section. W. Napa Fault.

Because quakes are measured on a different scale, a 6 is 100 times stronger than a 4, so yes, it is nothing to sneeze at, but still not nearly as strong as a 6.7.

I did hear them mention it but it wasn't familiar to me and so I didn't really catch the name. Just that it was a little to the west of Napa. It is not connected to San Andreas or Calaveras. Isn't there a Hayward fault too? In any case, it's not connected to anything it seems.

I see Starry has added some info on the fault name. I have never heard of it before.

Thanks Cali crew et al. for keeping me current with this -- much more pleasant and much more effective a way than merely watching this on TV.

Yes, USGS has them all labeled. There is a Hayward fault. Some are more active than others. I didn't know where to find this info on USGS. And when I bought my house, I didn't know it was on a fault line- found out later it runs right up my street! The things you don't even realize you should research in California Real Estate!

For me, going through them isn't what I'd call pleasant(and it woke me up)... but there are those who think some of them feel like roller-coasters.

I hate roller coasters! The 5.6 OK quake and another in California in '78 -- 4-point-something -- did in fact have elements comparable to amusement park rides (shudders).

DD went through a 5-pointer in Disneyland in April, and had to stop and think, am I on a ride? She wasn't, she was standing in a candy store on Main Street.

I remember in SoCal as a kid, there was a suggestion to take a long board and lay on it on the ground. lol

We had the 'duck and cover' for earthquakes and bombs in school and yep get in the doorway and hold on when at home or a building. I always wondered what would happen if you don't have enough doorways. Glad you are taking protective action.

Linask do you think the extreme drought might have something to do with this earthquake or future quakes?

People who went through the Northridge earthquake are telling me not to get under a doorjamb- even though that's what I was taught growing up. They say that doorjambs can still break apart. They are supposed to be the strongest part of a building. So now they advise you to get under a desk or table. You don't want to run outside, buildings can collapse. If I was in a meadow or open field, I'd be laying on the ground.
DH doesn't think the drought had any effect, but I do believe in the phenomenon of "Earthquake weather". They tend to occur when it's hot and dry out.

NAPA EARTHQUAKE UPDATE: City officials say 15-16 buildings have been red-tagged and are no longer inhabitable. 120 people have been treated for earthquake related injuries; 6 are in critical condition. There have been 60 water main breaks and it could take a week to fully restore water to certain areas. All Napa Valley Unified Schools will be closed on Monday.

I live about 20 miles from Napa and live in a 30 story condo building. Quakes always make me nervous because all I can imagine is the building being squashed flat with me in it.

Help! Mods! (hollers this).....we need to combine the Yoda and LinasK earthquake threads here! Just sayin'.

holy crap! WFG's back! happy to see you back

(sorry for O/T people)

Holy cow. What a difference geography and population density makes.

Napa seems to have quite a bit of structural damage.

A lot of old historical buildings, sadly, that can't be rebuilt as they were. Thankfully no one killed but so many still without power and I'd imagine very uncomfortable in the hot weather.

Prayers for everyone in the area.
