Tools for Earthquakes Visualization and Earthquake Networks creation

In this repository you will find the necessary tools for:

Visualization

• earthquakes epicenter visualization as 3D scatterplots on latitude, longitude and depth dimensions;
• the scatterplot points sizes and color vary according to the magnitude of the earthquakes;
• possibility to add a 2D map as a projection on the 3D plot, under the scatterplot.

Network creation

• using graphs, seismic networks are created;

split the seismic region in cubes

draw lines from earthquake to earthquake cronollogicaly to create a network

control the size of network by modifying cube sizes - bigger size, more earthquakes fit in a cube

• centrality measures such as connectivity (weighted/unweighted).

Motifs

• fundamental building blocks of graphs;
• motif detection using a slightly modified version of NemoMapPy - https://github.com/zicanl/NemoMapPy;
• motif visualization using Paraview.
  

Vrancea Triangles Visualization

California Triangles Visualization

• motif connectivity analysis;
• motif areas and volumes distributions, weighted by total energy and mean energy released in motif;

Autocorrelations

• spatial autocorrelations;
• temporal autocorrelations.

Miscellaneous

• waiting times;
• energy release distribution.
