The Quake-Catcher Network (QCN) is a seismic network that implements distributed/volunteer computing with the potential to provide critical earthquake information by filling in the gaps between traditional seismic stations. Microelectromechanical systems (MEMS) sensors detect vibrations within the frequency range of local seismic waves (0.1–20 Hz), so any internet-connected computer with an internal or external MEMS accelerometer can become a strong-motion seismic station. The QCN, a distributed computing project, uses idle computer cycles and MEMS sensors to increase the number of seismic stations, which may soon provide faster and more accurate detection and characterization of moderate to large earthquakes.
