Earthquakes

I wrote up a hypography on earthquakes a while back and figured it was time to update it.

The biggest problem with earthquakes - apart from the incredible devastation they cause - is the difficulty of predicting where and when the next one will happen.

This collection of links will give you a tour of some of the official sites about earthquakes, as well as some news, earthquake background, seismology FAQs and more.

Smile Re: Earthquakes

I have over the last year developed/aquired the ability to feel earthquakes; it is called the Charoltte King Effect. As I live just 51 miles from Mt. St. helens, lateley I find all the shaking very disconcerting.

Arrow Re: Earthquakes

___One of the new developments in the area of earthquake study in my area (Pacific Northwest USA) is the deployment of GPS stations. Previously, seismographs were the primary source for Earth movement data, and they remain extremely important.
___What has come to light using the GPS data however, is a phenomena they are calling 'slow quakes'. What they found is energy equivalent to a moderate quake is being released over periods of hours or days, rather than abruptly as in a 'standard' earthquake. I will keep looking for the link I read on this; I couldn't find it last night

___I haven't found that 'slow quake' link yet, but I wanted to point out another quake today, 5.4, at almost exactly the North Pole.
http://earthquake.usgs.gov/recenteqs...kes/usvuaf.htm
___We had 2 similar last week, & in general, this is unusual. As this is a spreading center plate boundry, it seems reasonable to conclude we have some signicant underwater volcanism events going on.
___It bears watching.

That's another link to a pretty cool site. You can click on the quakes to get siesmograph plots from tons of locations around the world. It's pretty satisfying to see an earthquake on that site, then see it on the news later that night.

Thumbs up Re: Earthquakes

___C1ay that is it! Thanks. Had you read of this before?
___ Bumab, that site has a cool graphic; I note they are piping the data from the USGS and just reformatting it. The sites I have been referencing are USGS sites.

Arrow Re: Earthquakes

___It is pretty cool I like being able to so easily take so many different views. I like the idea you put forward about knowing before the news does about quakes too. Even then, what a joke sometimes it is to hear all the misinformation they give out. Again, the web is so unique & cool that we have the 'real' data to evaluate.
___Then there is all the political ramifications for the geologists who work for the government; can't say anything even remotely threatening unless disaster is eminent. Still, it is they who are wisely spending our tax money to set up this data collection network & it is a marvel worthy of a hats-off to them.
___As Tormod suggested when he started this thread, it is the scientific investigation into predicting earthquakes to prevent loss of life & property that interest us all.
