Bonjour Vikalp,

This very much depends on your sensitivity objectives (i.e. what’s the minimum magnitude you would like to record with this network). If you’re solely interested in “large” magnitudes – and by large I mean greater or equal to 0 – then I’d say 5/6 stations would be enough.

I’d recommend using so-called “medium-period” seismometers, i.e. with a cutoff frequency of 1 Hz. This has the benefit to be much cheaper and easier to handle than broader band seismometers, those being dedicated to larger magnitudes.

Hope this helps a little.

Finest regards,

PFR

Hello Pierre,

My objective is to identify the regions where seismic activities occur within a depth of 200m which would affect the dwellings and estimate the seimic hazard in the closed mining area.Will five geophone sufficient for these two objectives?

Kind regards
