“We had this magic key, this magic magnetic profile,” Pitman said. “We were able to date it and eventually use it not only as a tool that proved continental drift but a tool by which we could actually reconstruct the pattern of drift, that is the relative position of the continents, and the actual timing of the separation of the continents.”

For his pioneering work in rock mechanics and his skill at communicating earthquake science, Scholz is being honored on April 20 by the Seismological Society of America with its top award, the Harry Fielding Reid Medal.
The bottom of the ocean just keeps getting better. Or at least more interesting to look at.
Ancient faults that formed in the ocean floor millions of years ago are feeding earthquakes today along stretches of the Alaska Peninsula, and likely elsewhere, a new study suggests.
A new study in Science questions the provocative idea that climate change may shape the texture of the sea floor. A Snickers bar helps explain what’s really going on.
A new video produced by Columbia University tells the story of what the research vessel Marcus G. Langseth is all about.
Researchers at Lamont-Doherty Earth Observatory have published a new study showing that a tsunami of unimaginable size swept over the Cape Verde Islands some 73,000 years ago. The discovery may have implications for the potential for modern hazards. READ THE FULL SCIENTIFIC STORY
The architects of Columbia’s modern Northwest Tower, at the corner of Broadway and 120th Street, made good use of some beautiful stones. In their polished and swirling surfaces, they tell a story of the clash of continents and the processes by which mountains are made.
The most important lessons drawn from geology are that the earth’s climate can change radically, and rapidly. We can’t say precisely at what CO2 level we’re in danger of melting Antarctica, but that threshold could be reached in 150-300 years, if CO2 levels keep rising at the current rate.
