Q: I'm using a single three-channel seismic recording of one earthquake to include in a MATLAB code distribution. I just want to know if it's OK to include the sample dataset in my MATLAB package.
A: In general, the data at IRISDMC is considered open for your use. Please be sure to cite that you got the data from IRIS DMC and indicate the seismic networks in the data you represent. More information on citations.
