Catch a Quake
Previously at Bench Press we’ve written about the power of distributive computing and it’s ability to pool resources from volunteers over the internet to tackle projects on protein folding and the search for extraterrestrial intelligence. As distributed computing approaches mainstream, numerous projects focusing on a variety of questions have emerged. 
One project that caught my eye is the Quake-Catcher Network (QCN). The network is described as
a collaborative initiative for developing the world’s largest, low-cost strong-motion seismic network by utilizing sensors in and attached to internet-connected computers.
The QCN utilizes accelerometers attached to computers to monitor for vibrations. Vibrations detected by the accelerometer are then recorded and compared to readings from other computers in the network. Only when a sufficient number of computers report comparable readings at the same time will the data be reported as an earthquake. Most recently the QCN detected a magnitude 4.4 earthquake in the Los Angeles area yesterday morning. The data generated from QCN participants can be seen here.
The beauty of the QCN is the enormous cost savings their approach can provide in comparison to traditional seismic networks like those run by the USGS. New accelerometers are now much more affordable. Sensors that plug into a USB port can cost less than $50. In addition, an increasingly common feature for laptops is a built in accelerometer to detect sudden movements like drops in order to shut down components to protect them from damage. These accelerometers can be utilized and provide a fairly large potential participant base who merely need to install BOINC and join the QCN project to begin providing data to the network.
As the number of QCN participants grows the heads of the project, Drs. Elizabeth Cochran and Jesse Lawrence, hope the network will provide not only a wealth of data for geologists but potentially a small bit of warning in the event of a large earthquake for those miles away from the epicenter. Currently, Drs. Cochran and Lawrence are working hard to increase the number of participants while also providing educational tools for use in schools to teach about earthquakes and science behind them.
Living in San Diego I think I’m in a prime location to help out so I look forward to contributing some data to the QCN (magnitude 4.0 or less please!).
