Abstract

A review of seismicity of the Armenia Republic territory and neighboring countries for 20162017 is carried out, information about seismic stations of Armenia network is given. Testing of a new digital seismograph developed in the city of Gyumri was carried out, example of its recording of perceptible earthquake is given. More than 7000 local earthquakes were processed, 2025 of them are included in the consolidated catalog. Within the Republic, the highest level of seismic activity was recorded in the North, in the source zone of Spitak earthquake 1988 with MLV=6.9, I=10. The recurrence graphs for 2016, 2017 and 19932017 have shown, that the long-term coefficient =0.49 corresponds to its normal value for Caucasus, but its values for 2016 and 2017 are somewhat underestimated as regards to its absolute value.
