Seismic networks provide crucial data to scientists and
the public about recent earthquakes, both large and
small. These networks record waves that propagate
away from the earthquake source and provide a host of
information about the earthquake including magnitude,
location, and how much slip occurs during an earthquake.
Included in the details of each seismogram is information
about the rocks and sediments which the seismic waves travel.
By increasing the density of seismic stations, we can rapidly
detect and locate earthquakes to provide an advance alert,
improve our understanding of earthquake rupture and the
associated seismic hazard, and generate in real-time, state-ofhealth
information.
We have constructed a new inexpensive initiative to
augment seismic networks quickly by using Micro-ElectroMechanical
Systems (MEMS) accelerometers and distributed
computing techniques called the Quake-Catcher Network
(QCN). Its use is expanding rapidly and increases the density
of ground motion observations throughout the world [1]. In
this paper, we describe our network including the people who
volunteer to participate, the location of sensors in the system,
detection and analysis of triggers from megadata, tagging
with accurate time, and the MEMS accelerometer sensors that
we use.
