Community Seismic Network
A low-cost dense seismic network

CSN - Available Data

The CSN sensors are largely hosted by volunteers and, although they are decimated to prevent recording human voices, can detect events such a door closing, elevators moving, etc, which are not part of our mission. Out of respect for the privacy of our hosts, we do not distribute continuous waveform data. However, when there is an interesting earthquake, the data are available are shown in the tables below. In each entry, the 'Link' column is a link to a zip file containing the time series for each station in the network (at the time of the event). The data are in SAC (Seismic Analysis Code) format, a binary format commonly used with seismic waveform data.
