Abstract

Summary

When conducting geothermal research, one of the risk factors is induced seismicity, which can occur during the operation of geothermal wells. It is well known that local geological and physical conditions, together with the magnitude and distance to the seismic event, can significantly influence the intensity of ground shaking at the Earth’s surface.

In global practice, a key parameter for assessing local seismic conditions is the average shear wave velocity in the upper 30 meters (VS30). This parameter is crucial for determining the near-surface amplification of seismic waves during earthquakes.

For the Litoměřice region (Czech Republic), where geothermal research is being conducted, the VS30 parameter was calculated using the Wald & Allen method. This made it possible to obtain regional schemes of seismic wave amplification and the classification of soils categories at the Litoměřice site based on their seismic properties according to Eurocode 8.
