- Аннотация: The distributions of weak (M>0) earthquakes occurrence times have been calculated for five regions of Central Asia where long term instrumental seismic surveys were being performed. The rage of considered spectral periods was from 1 to 48 hours; the lag being half an hour. The presence of significant, high-Q spectrum extrema of 24 and 12 hours has been revealed for all used catalogs. Observed periodicities disappear near entirely for major seismic events of magnitude M>2.2. The temporal plot of diurnal periodicity seems to be different at various regions. Possible causes of the phenomenon have been discussed. No considerable effect of lunar-solar tides over seismic emission variation has been found.
