I'm trying to find 3-component records of the P-wave arrivals of a variety of earthquakes at seismic stations (specific earthquakes or stations aren't important, I just want a small library of these arrivals for a machine learning project). I expected there would be labeled databases of this kind of thing where I could simply browse by earthquake or station and download the data. However the request process appears much more complicated and honestly I'm very confused.
Is anyone familiar with how to query these databases?
