[MSNoise] MSNoise Digest, Vol 31, Issue 13

[Esteban Chaves]

Hi Asthon, 

So far, I think we can compute the CC with a minimum of 3 stations (Am I right Thomas?). What I did for Costa Rica was computing seismic velocity variations for selected station pairs instead of the average seismic velocity change for the whole N array. You can adapt the scripts for this...

It would be really cool if we can implement sub-arrays from the N stations and monitoring  these sub-arrays and compare results.  


Changing gears a bit: 
** Another cool idea that I am throwing here is to implement a tool/ function that allow us to use the final Green’s functions as virtual earthquakes!! So we can perform moment tensor inversions (for instance) and make some seismic hazard analysis.  

Cheers; 

-Esteban
