The Community Seismic Network (CSN) is a low-cost, MEMS-sensor seismic network with smaller average station-to-station spacing than stations for other networks. We have downloaded and processed CSN data for 29 earthquakes with M > 4 from 2012 to 2023 using NGA procedures. Visual checks of data useability were applied to distinguish rejected records form records with clear seismic signals. We compare recordings from proximate (within 3 km) CSN and non-CSN (generally SCSN or CSMIP) stations with usable signals. Results show no systematic differences for peak acceleration and similar spectra when the CSN motions have large usable bandwidths.
