# Seismicity Map and Rate using Basemap and Pandas

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…

# Matplotlib Basemap tutorial 10: Shapefiles Unleached, continued

Following the comments on this year-old post I’ve had a look at pyshp which seems a little more maintained (the last line in the changelog is 1 year old…), and it is indeed a quite nice piece of code. I thus rewrote “Tutorial 7” to use this module : The goal: The data: http://www.gadm.org/ saved…

# Last Earthquakes tool – ETS powered

While in Indonesia last July, I created a small tool for the Kawah Ijen observers to allow them to search and plot teleseismic events and to calculate theoretical arrival times of the waves at the Ijen stations. It took roughly 2 hours to have a working version of the software, with: a GUI to plot…

# New on Géophysique.be: Gallery

Everyone used to search for code snippets on the web know the importance of a “Gallery” linking to all examples and tutorials… So, here is my really ugly Gallery :

# Matplotlib Basemap tutorial 09: Drawing circles

In the previous tutorial, I defined a “shoot” method to compute the landing point of a shoot from one point, to a given azimuth and distance. Using this logic, it’s possible to find the points situated at a given distance from a “centre” point, a circle. The goal: Drawing circles of a given radius around…
