Pandas and Obspy are incredible pieces of software that definitively make my life easier ! In this tutorial, we will get seismic Event data from IRIS using Obspy, then analyse the catalog using Pandas, to end up with a “Seismicity Rate” per month, splitting events in magnitude bins, graphically speaking: To get the data, we…
Imagine we want to plot a map of the seismic activity in NW-Europe and, at the same time, count the number events per month. To get a catalogue of earthquakes in the region, one can call the NEIC (note: this catalogue contains a lot of different stuff, i.e. quarry blasts, mining-induced events, army-directed WWI&II bombs…
In the coming months, I’ll prepare some tutorials over an excellent data analysis package called pandas ! To show you the power of pandas, just take a look at this old tutorial, where I exploited the power of itertools to group sparse data into 5 seconds bins. The magic of pandas is that, when you…
