CSN - Available Data
If you use data available below, cite:
"Community Seismic Network. (2024). Community Seismic Network Earthquake Dataset: http://csn.caltech.edu/data/ [Data set]. CaltechDATA. https://doi.org/10.22002/h2f92-ejv09."
The CSN sensors are largely hosted by volunteers and, although they are decimated to prevent recording human voices, can detect events such as 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 available data 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.
