Historical seismicity and geophysical survey of tectonics in the Cheb area
Hrdličková, Markéta ; Fischer, Tomáš (advisor) ; Horálek, Josef (referee)
This work deals with the documentation of the space-time distribution of seismic activity in the years 1897-1908 in the western Bohemia, using original sources. The region of Vogtland / northwest Bohemia is known as one of the most interesting European regions with the occurrence of earthquake swarms. Seismic catalogs are available for this area only for the last few decades when the seismic stations were in operation. For the earlier period only macroseismic observations are available. The aim of this work is to compile the catalog of earthquakes for the years 1897-1908 with the use of the macroseismic data. This requires estimating the origin time of earthquakes using the distribution of the macroseismic observations in time. First, the original historical materials Mittheilungen der Erdbeben-Commission der kaiserlichen Akademie der Wissenschaften in Wien were compared with geophysical catalog of Vít Kárník Erdbebenkatalog der Tschechoslowakei bis zum 1956, which is a summary of selected data from the original materials. Macroseismic observations from the catalog were digitized in the form spreadsheet tables. It turned out that in most cases the data in the Kárník's catalog represent observations of earthqukes and in isolated cases these are the seismic events themselves. Cluster analysis was...
