Question about the algorithm #1

Open edemqs opened 1 month ago

edemqs commented 1 month ago

Is there any way to use this code to detect duplicates of seismic events? I am looking for an algorithm that allows me to eliminate duplicate events within a database that contains information from different seismological agencies. For example, if I use 10 seismological agencies, I could have up to 10 duplicates of the same event that has been reported by all seismological agencies. I would be very grateful if you could guide me on how to solve this problem, I think your algorithm could be of great help.

Thank you so much.

Hi! I haven't tried running this algorithm with multiple catalogs so I haven't run into the problem of having duplicate events before. If you loaded the data compiled from different agencies, you could possibly just filter through all the events and remove ones that have the same exact timestamp and location! I'd be happy to try and help as best I can with that. However, with this particular algorithm, I think the Zaliapin & Zion paper intended for it to be parsing out events caused by previous events, not duplicate ones!
