Earthquake researchers are turning to a new tool to help them quickly gauge the location and severity of newly occurring temblors—Twitter.

The USGS has developed a prototype application to search and capture Twitter feeds that make reference to earthquakes, according to Paul Earle, at the agency’s Earthquake Information Center in Colorado. But it’s still in the beta testing mode.

Longer term plans for making use of the quake-related tweets may include publishing maps showing where they originated, but Earle says that’s still well off into the future.

Still, as the graphic below shows, there is strong evidence already available to suggest that there will be plenty of content for the USGS program to work with as soon as it is fully operational.

The founding Fathers saw the U.S. Constitution as a dynamic document that would evolve and change over time. Writer and activist David Swanson believes we’re long overdue in getting to work on that.

In his new book, Daybreak:  Undoing the Imperial Presidency and Forming a More Perfect Union, Swanson tracks the gradual accretion of political powers in the office of the presidency—something that has been underway for most of our national history, but which accelerated markedly in the past eight years. In his analysis, that is dangerously undemocratic, but its hardly the only place in our national governance where that is a problem. Another is the U.S. Senate, particularly the convoluted procedural practice of the filibuster, which Swanson would like to see ended.

The calls for impeachment of Dick Cheney or George W. Bush or members of their administration have diminished over the past year, but Swanson notes that leaving office does not remove or even lessen their vulnerability to such charges. And he contends that pursuing impeachment against any of the potentially culpable former officials would serve the further purpose of reasserting the strength of the House of Representatives.

The politics of 2009 were sharply different from the years before, Swanson observes, as much of the activism that had mobilized against the wars in Iraq and Afghanistan got caught up in the Obama campaign, and has not yet re-established itself. He speculates that the anti-war effort might actually be more effective today if John McCain had been elected instead.

David Swanson will be speaking at the Glaser Center in Santa Rosa at 7 pm on Wednesday, Jan. 13, hosted by the Progressive Democrats of Sonoma County.

The pathway to sustainability depends on morphing conflict into consensus, and when it comes to food systems, that’s what Sebastopol’s Ag Innovation Network is all about.

Even in areas where there is a history of deep distrust between factions within the agricultural sector, such as Sonoma County with its history around the 2000 Rural Heritage Initiative, Ag Innovations Network CEO Dan Schurman (left)  says they are committed to a process that works to heal past rifts.

Karl Marx was an economic and social theorist, and a self-described communist. But one thing he said he was not, was a Marxist.

Jerry Levy is a college professor, a longtime leftist activist and an actor who has been performing Howard Zinn’s Marx in Soho frequently for the past six years. (He's seen in character at the left.) He notes that the play’s central premise places the 19^th Century writer and theorist into the present day, giving Marx a platform to comment on contemporary issues.

Although Karl Marx and Vladimir Lenin are often linked in connection with the Russian revolution a century ago, Levy says that Lenin is largely ignored throughout Marx in Soho.
