Let's get away from how warm we are right now, and go to good, honest physics. I was always more interested in earthquakes, but there haven't been many lately. I'm mainly interested in the proper plots for my home-made seismometer.
I have used kst, which is the kde plotting package. It's great, but then I found Obspy, which is more geared to seismic. I installed it into an Anaconda environment, which is like a Python, scientific container. If you are on a big Linux machine, you don't have to worry about all the crap on the main machine, or bothering the sysadmin. This makes a uniform environment for everybody.
I'm following the obspy tutorial right now, and everything is working.
