For several years, I've followed earthquakes at this site: http://earthquake.usgs.gov/eqcenter/recenteqsww/
Commonly known as the ring of fire, the view daily shows how the tectonic plates are moving and relieving stress(earthquakes). I have no background in geology but the trend that I have seen is an increase in activity on the east side of the Pacific Plate.
From Chili to Alaska, acivity has been steady. Recent acitivity near Yellowstone(most likely volcanic) is showing more and more frequently. Even a predomenantly inactive fault area like the New Madrid zone has shown an increase in activity. While many people are terrified at the thought of being in a tornado, I'm curious to what types of preperation, if any, you have made for likelyhood of a major earthquake on the left coast?
The other site that I check is on valcanic activity but this site changes very little and information on volcanic activity hits the news quickly regardless of what part of the world it is in.

I have not been checking lately. I was truly amazed when I first ran across that site. Did you catch the abnormally large waves hitting Hawaii? That would be a good method of causing a land slide, tsunami and bye bye west coast?

Not sure there is a lot that can be done to prepare for a large event besides not be there :)

Been watching that site for over nine years. Since I live in Shakytown and almost on top of the Elsinore fault, I am very interested in earthquakes. We have about 300 to 500+ earthquakes per day here in Cali. Most of them are too small to feel. OH! I think we are having one right now! :ohmy: Never mind. It was just my breakfast moving. ;)

Aside from the New Madrid fault there is also a fault that runs through the city of New York that has the potential of causing major damage.

Swifty, check out this site, www.syzygyjob.com Go to Frank Condon's forum. He has developed a method of predicting earthquakes by measuring the acoustic emissions from the breaking rock in the earth prior to an earthquake. He has found that quartz rock, deep in the earth, starts to break up a few days prior to a major earthquake. When it does this, it emits small radio type of signals from the earth. Similar to a quartz crystal radio set. He has developed tools for measuring these signals and can predict an earthquake within a day or so. He is very accurate with his predictions.

He can tell you when an earthquake will strike but he still can't pin down the exact location. Although, he gets very close. There are a lot of kooks in the other forums on that site but Franks forum is pretty straight-up.

The biggest danger in the Ring-of-Fire is volcanic. Many volcanos are ready to blow including Yellowstone. If that one blows, we are all in trouble.

HANG ON!!!! I think we're havin' another one! :yikes:

We used to have a member here on DRN who could predict earthquakes based on amount of oil brought to the surface and the resultant lack of lubrication to the tectonic plates :)

At least that was her theory :rotfl:

Synethic or Petroleum ?

This's interesting stuff,.. just for discussion purposes, here's my own theory, If the plates are moving they're continuing to relieve pressure, and keeping things relatively stable,.. its when they stop moving, (ie hung-up) that's when all hell could let loose. :whoa:

Thanks for the link! I'll have to add that to my Fav's. I've just been really curious since 1989. The overwhelming amount of information available today is mind boggling.

Other than asteroids hitting us, the mega tsunami has to be second worst. Then the volcano, then earthquake for catastrophic damage. Both of them are capable of causing the mega wave is the real kicker. There has been some really good HD shows on that were not all tree hugger crap. I was shocked to say the least! That Madrid fault would sure test a lot of areas that are not anywhere close to being constructed for such events. Sweet home Chicago for one. http://www.iris.edu/seismon/

I remember her oldguy. Cali with a K. What a piece of work she was. :coocoo:

Foxforks.

You are correct about Chicago. If the New Madrid goes off, Chicago would be devastated with all of its brick buildings. Masonry buildings don't do very well in an earthquake. The last time they had a quake on the New Madrid fault it made the Mississippi river run backwards for a few days. Of course, there were no skyscrapers back then so the human toll was not as great as it would be today.

Here in California, most of the buildings have been retrofitted to rock and roll with the quakes rather than fall down. Some of the really tall skyscrapers are actually built on rollers. Most all of the brick buildings have already fallen down in previous quakes. Plus, here in Cali, most of the houses are stick built. They tend to move about and flex with the quakes rather than fall down.

Also, there is a bigger danger of a tsunami on the East coast due to a large part of an island that is slipping and ready to sluff off and fall into the ocean. I can't remember the name of the island but they said if it falls into the ocean it could cause 20+ foot waves to hit New York City.

Shaw.

That is pretty much what happens before a major quake. As long as the faults are moving and readjusting, there are not any major quakes. As soon as the smaller quakes stop, the pressure starts to build and then over a two or three day period, we will start to get mag 4 or 5 quakes along the faults. These usually lead up to a 6 or 7 mag quake. The faults actually start to let loose slowly over a pierod of several days with rock crushing deep in the earth. They take a while to work to the surface.

If you follow all of this stuff, earthquakes are pretty easy to predict. The USGS won't even try to predict earthquakes for fear of being wrong. Their theory is, if they predict an earthquake and it doen't happen, the public won't listen to them the next time. Better to let a bunch of people die than be wrong I guess.

Earthquakes are just the planets way of letting us know who's really in charge. :nod: And it ain't us. :whoa:

CORRECTION: We get 300 to 500+ earthquakes per week in California and Nevada, not per day.

Foxforks you may be correct at least until Yellowstone decides to let loose. That will be one that could wipe out a lot of north America and a good portion of Europe from the debris

Actually I guess it is really the volcanic part of Yellowstone and not the earthquake

Haven't they said that even though Yellowstone is ready to pop.....they still have no clue when that will happen? I remember a tv special on the subject, and the window of when it could blow was VERY wide. That would sure get ugly.

The city I live in; Evansville, IN; is right smack dab on a major fault line. I wanna say it's the New Madrid as well. I can't recall exactly. We've had warnings of a BIG one for a long time. People we're down right terrified in the 80's. It's scary...but there's not really much you can do but remember that momma nature IS the one in charge. I live in an area here called "Reitz Hill". It's a really big hill overlooking the city. Geologists have said its the safest spot in our area. good to know I guess!!

20 footers on the east coast for sure would cause issues. The theorized tsunami that COULD start from a landslide in Hawaii would be a heck of a lot bigger! Thats why It sparked something in the backside of the brain when I seen the inexplicable 30+ footers hitting Hawaii. I sure would like a big screen, parked on that world seismic graph I linked to, with updates!

Seems that this topic is relevant again.
