About Quake-Catcher Network Continual MonitoringThe Quake Catcher Network (QCN) is a research project that uses Internet-connected computers to do research, education, and outreach in seismology. You can participate by downloading and running a free program on your computer. Currently only certain Mac (OS X) PPC and Intel laptops are supported -- recent ones which have a built-in accelerometer. You can also buy an external USB accelerometer.
QCN is based at the CalTech Division of Geological and Planetary Sciences (GPS). From 2007 to 2015 QCN was based at the Stanford University School of Earth Sciences.
