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.

Electrons move faster than earthquakes, giving new automated alert systems a few key seconds to warn outlying areas that some shaking is on the way.

This project is moving forward as quickly as possible, says Doug Given, but to be fully effective it requires the installation of many more sensors along the biggest known fault lines.

In setting all this up, priority has been given to the San Andreas Fault, one of the longest and most active in all of California.

A Santa Rosa social activist has returned from the climate summit in Copenhagen eager to implement some new ideas, and with a deeper appreciation for Sonoma County’s actions on the issue.

In addition to the most visible benefits of her trip, Evelina Molina says it also served to reinforce an important message for the youth she works with at the North Bay Institute of Green Technology, which she recently co-founded in Santa Rosa.

Seeing what other nations and local communities around the world are doing to address climate change was inspiring, says Molina. But it also changed her perspective on what is being done here at home.

Evelina Molina, Kevin Danaher,  and Sean Holt will be part of a panel, moderated by Norman Solomon, that will report back to the local community on the experience and outcomes of the Copenhagen Climate Conference. The free public session will be at the Finley Community Center (2060 West College at Stony Point) in Santa Rosa on Saturday, Jan 9, 2-4:30 pm.

Far out in the oceans of the world, away from the continents and even shipping lanes, vast floating seas of plastic garbage form an intractable sort of water pollution, something the bay area’s Project Kaisei  is working to combat.

The north Pacific gyre is 700 to 800 miles across, explains Mary Crowley,  co-founder of Project Kaisei, but it is not a solid mass of garbage so much as a shallow stew of floating debris.

The north Pacific Gyre is believed to hold the largest plastic Vortex anywhere on Earth, but Crowley observes that there are numerous other gyres across the seas, and each of them have their own growing expanses of floating garbage.

Returning from the Pacific Gyre, the Kaisei sailed under the the Golden Gate Bridge on August 31st. Kaisei is a Japanese word meaning "Ocean Planet."
