The present paper reports a study and refinement of quality parameters for data acquired using the seismological network in the area of the Lena R. delta. The main estimated metrics were chosen to be sensitivity and azimuthal gap between neighboring stations. For assessing scenarios to be used in the deployment of network stations we chose the area where we estimated mean sensitivity as having the highest priority, and mean azimuthal gap. We planned the station locations so as to optimize the network sensitivity with an eye to ensuring that the mean azimuthal gap should be below 180°. This assessment of the current arrangement resulted in the decision to dismantle the SML09 station to transfer the equipment to a more promising location. In addition, we propose a scenario for the deployment of additional stations increasing the mean sensitivity by 0.49 in the area of interest. This would result in the number of recorded earthquakes increasing by a factor of 2.08, as follows from the GutenbergRichter relation.
