Mount Rainier Magma Mapping

A team of geologists and geophysicists have imaged the path of a Pacific Northwest volcano's molten rock, from the subducting slab to the upper crust. [more inside]

They're not available from Edmund Scientific

Later this year, geophysicist Dan Lathrop's DIY Planet Earth will be filled with liquid sodium, weigh in at 26 tons, and will be spun-up to 80mph at its equator in an effort to discover how the earth's magnetic field is generated. Currently undergoing tests, even those can be pretty impressive.

"What a beautiful world this will be. What a glorious time to be free."

It's been nearly 50 years since the beginning of the International Geophysical Year (IGY), an 18-month period of scientific activities and discoveries that ran from July 1, 1957, to December 31, 1958. Both the US and the USSR launched the world's first artificial satellites during the IGY (Sputnik 1 and Explorer 1). Other achievements of the IGY included the discovery of the Van Allen radiation belts and the mapping of mid-ocean ridges. The IGY also inspired at least one artistic endeavor: Steely Dan's Donald Fagen wrote his 1982 solo song "I.G.Y. (International Geophysical Year)" [YouTube] as an homage to 50s optimism.

More than junk science?

Quake to hit LA "by September 5," predicts a geophysicist at UCLA's Institute of Geophysics and Planetary Physics. Some skeptical, while others say it's not junk science.

Richter calls it a 3.2, but I just call it shaky.

Minor Washington state quake. It's been a while since I've experienced and earthquake, so when tonight's little one hit my hometown (a mere 3.2) I was a little shocked (and a little excited). I was also really impressed with the seemingly instantaneous response by the USGS and the University of Washington's GeoPhysics Dept. on their websites classifying it.

In the olden-days (eg- pre-Internet) I'd have to wait for the early morning news to find out any information about it, but through the miracle of HTTP I have all the info I want mere seconds after the event. In fact, less than 15 minutes after the quake the USGS site had over 260 responses on their website about the quake from people who felt it and left comments on their site.

I wonder if there are other sites that help classify and/or disseminate information about other naturally occurring phenomenon (hurricanes, tornadoes, etc.)... anyone, anyone?

Hubbert's Peak: the impending oil shortage

Hubbert's Peak: the impending oil shortage Is this the REAL reason behind the push to invade Iraq? In 1956. M. King Hubbert, a respected petroleum geologist, predicted - to within a year! - the peak in US oil production: 1970. US oil production has declined every year since. Using the same statistical methods, others now predict a world peak in oil production within a decade or even as early as 2006.
