Comparison of nearby earthquake records made on hard rock ground and on ice cover of Lake Baikal

The paper presents the main results of comparison between the records of four nearby earthquakes made on the ice cover of Lake Baikal and on the hard rock ground (seismic station located in Listvyanka settlement). Since the discovered differences between the records may be due to several factors—sedimentary cover, water medium, ice cover, interfaces between media, and microseisms—the experimental investigation and understanding the main regularities of seismic waves conversion will require the creation of a database of earthquakes recorded on the ice cover of the lake and statistical analysis of record processing results.
