I have 2 kinds of events I want to examine correlation between, lightning strikes and earthquake events. The lightning strikes are defined by lat lon points and a timestamp, whereas I have represented the earthquakes with buffers of variable radius(corresponding to earthquake magnitude) around an epicentre. I am interested in the time just before a quake happens, and whether seismic processes effect lightning activity. A graphic of my data is included below, where colour gradients represent times.
I feel like the Space Time Pattern Mining toolbox would do what I need, but I only have access to ArcGIS for desktop 10.2.2.
I am able to code stuff in python if needs be but Im not sure where to start.
