Problems and prospects of creating a global land–ocean seismic network

Abstract

The paper discussed the advantages and limitations of seismic signal detection on the ocean bottom. The need to create long-term seismic monitoring systems in areas of industrial development on the shelf and continental slope, as well as in areas with high seismic and tsunami hazards, is justified. The results of employing broadband bottom seismographs during expeditions of the Shirshov Institute of Oceanology of the Russian Academy of Sciences (IO RAS) are described. Autonomous broadband bottom seismographs with operational communication via satellite or radio channels are proposed for creating a global marine seismic network.
