How's your day

My Dad gave me a Nat. Geo (may have been Life Magazine - i dont remember) to read - er... to look at pictures while he read it is what really went down when this quake happened.

It was fascinating to me even when it make no real sense at the time..how could everything get all torn up like that, big hills where there were flat streets before, etc.?

there is a video of actual B&W film from a boat during the '64 quake.. i couldnt find it or i would have posted it .. that shows this big "cliff" in the middle of the water right off Valdez, and water cascading over it DOWN (like Niagara Falls) into a big, unseen depression or maybe a crack in the ocean floor. stunning film - - a big hunk of the ocean floor was pushed up (or a big piece collapsed) by the quake, just like in the scenes in Valdez itself.

My secret hobby ..studying rocks .. is being revealed. I'll cool it on this thread so we can keep it light. :icon_wink:

One cool thing about driving the US? I study the road-cuts. really cool stuff. Love drive thru Pennsylvania JUST to look at the rocks exposed (the strata, the ancient folded now solid rock, etc.) when the roads were built.

Whenever people start talking about earthquakes, hurricanes and tornados, I suddenly remember that snow isn't all that bad.

Found it. whole thing (4:30) is interesting but the scene i referred to starts at 1:20 and ends at 1:36.

My time in Ca. (Navy) I was on the ship for every one including the one you mentioned Oct. 17, 1989 we pulled out of S.F. a couple of days prior thought we might be sent back to help but never got called back so we went home to San Diego.

I-68 in Maryland. Sideling Hill. drove through this each way. spectacular.

the result of all this continent crashing and the Earth moving the furniture around. the Atlantic Ocean has opened and closed a couple of times.

when it closed, some big-a** piece of land plowed into whatever was going to be North America, forced out the pre-historic Atlantic, and pushed up the Appalachians, themselves once Himalayan in height (think Mt. Everest). Of course, they have since eroded to a 10th of their original size.

while that was going on, all that unimaginable pressure heated/folded solid rock (like pushing a flat throw rug toward the middle from each end - folds and ripples get created), and whatever 100's of millions of years later we are cutting through that ancient rock and can see the evidence of how it all went down.

The first link is where the pictures came from.

The second link below is the one for any geology nerds like me. 350 Million year old rocks are exposed at Sideling Hill road cut.

Update. Thars' coal in the Sideling Hill Road cut!

9.2 and most powerful in North American and history and 2nd most powerful recorded in the world.

I had been stationed at LAX for 2 months when Northridge went off. Being from Arizona and not used to the ground moving under any conditions. My whole family was thrown out of our beds, we got the kids downstairs and stood in a framed doorway. Watching walls and floors move taught me just how fragile life is. This was just after the riots and just before the wildfires, I was glad to see another assignment.

October 17th, 1989 Loma Prieta 6.9 magnitude.

Remember that one? If you were watching the World Series you would have seen it on TV. If I remember correctly it was just after 5:00pm PST. I was sitting in my original office in Danville, built for earthquakes, when it hit. I t lasted long enough for five of six people to run out of the office into the parking lot. That was 20 seconds and I stayed in the office sitting in my chair since I wasn't concerned.

I was watching the game. After a few seconds I realized something was happening. Nationally, it was a media event, all channels all the time. It looked pretty apocalyptic. I've been through a few hurricanes. Ike ripped me good. I knew it was coming.

Earthquakes are pretty scary looking on the tube. I lived on Beale in '73-74 and never felt a thing. We even visited the wharf in SF hoping to get a glimpse of Carol Doda in person. No shaking on either count.

I-68 is one of the most scenic mountain cruises in Maryland! And a main travel corridor east -west.

you bet it is...the whole drive stunning then this roadcut in the distance and WOW.

wish it was fall when i did the drive (it was summer) but still a sight to behold the sumptous countryside.

 

[70bigblockdodge]

Plenty of time to see the rocks as you creep up some of those hills at 25 mph in a grossed out truck.

 

[furyfinn]

An earthquake, what is that? lol

Beautiful fall colors last week in Door County, Wisconsin when I was there.

i did it...with a half-ton truck (needed my dually but it was out of service) towing a car I bought.

since the truck didn't have the "nads" to do anything more than 45mph on a couple of grades, I had time to marvel at the rocks up close :icon_pirat:

something on my list. i recall Wisconsin driving my daughter from Michigan to Minneapolis back in 2011. again it was summer and i vowed to try it again with the colors at their peak.

oh they are comin'...in about 80M years when Africa has closed the Mediterranean, before dumping Poland (Germany, Denmark, etc.) into the Baltic sea.

so there's lots of time to prepare :icon_smile:

 

[amazinblue82]

trying to make this the last one of these...you folks get the picture.

hope anyone interested gets a chance to "look at the rocks" - safely - as you travel the roads. wonderful things right outside your window. :icon_smile:

The San Andreas Fault system near Palmdale. Whole lotta squeezin' and shakin' goin' on over the eons to fold solid rock like this.

Those are layered ("stratified") rocks formed flat at the bottom of pre-historic lakes/oceans, or lava flows on flat plains, etc. , then crashed together, heated and folded, and cooled in these bizarre shapes. some even "vertical" now.

322 between Harrisburg and State College has rocky road sides with various layers that are blatantly in your face. ....Gorgeous stuff

Oklahoma now surpasses California in the number of earthquakes annually. It's attributed to fracking by the anti-oil people, mostly. Personally, I believe that the activity has simply reactivated long-dormant faults, rather than actually causing the quakes. Fracking is done in over 40 states in the US, and only three have seen an increase in quake activity. I'm not really worried.

We did feel the 5.6 and the 5.0 that hit central OK in the recent past. Shook things up and made the dogs get all worked up, was about all.

dont recall ever being on that stretch...BUT i was on I-80 going to/from Philly and saw some magnificent road cuts. also on I-76 traveling to/from Pittsburgh and Baltimore.

I even saw what looked like coal seams close to the surface. may not have been but there were some exposed, folded black rocks that looked like coal to me zipping by at 65mph.

this is a internet picture outta Utah (US Hwy. 6 near Helper, UT) of an exposed coal seam..what i saw in PA looked like this but folded.
