MESS is a matched filter earthquake detector
- MESS Workflow
- Match: calculate CC trace on every station (matched filter)
- Expand: expand peak values on CC traces
- Shift: time shift to origin times for all CC traces
- Stack: stack CC traces of different stations & detect events on the stacked trace
- dt_p and dt_s are picked by cross-correlation
- Usage (see example_mess_workdir)
- Prepare template phase file (e.g. run PAL) & cut template waveform
- Run MESS

MESS is a set of codes. All you need is to setup proper Python environment. This can be accomplished easily by installing Anaconda, Obspy, and Pytorch sequentially. Or you can use the env/mess.yml file with conda.
