SeisClient Tutorial

Request Greens function and the synthetic waveform from point sources, multiple-point sources, and finite faults for various applications such as earthquake source characterization, induced seismicity monitoring, and Earthquake Early Warning (EEW).

SeisCloud provides the remote data server that hosts the 3D SGT database.

SeisClient can request precise 3D Greens’ functions and theoretical seismograms from SeisCloud.
