Study of seismic regime in northern part of the Moravo-Silesian Region
First studies of given region were initiated in 1997. Monitoring of regional seismic
activity, establishment of solitaire stations, identification of records and detailed
interpretation of seismic events are basic activities. Obtained data is used also for
study of velocity field of seismic waves on region under study and for determination
of the character and properties of recorded surface waves generated by quarry blasts.
Conduction of the seismic station Ostrava-Krasne Pole (OKC) which is part of the Czech
Regional Seismic Network is realized in cooperation with the Geophysical Institute of
AS CR, Prague and VSB- Technical University of Ostrava. In the frame of cooperation
with the Institute of Physics of the Earth in Brno (IPE) the exchange of seismic data
related to local tectonic events has been performed.

Interpretation and modeling of effect of seismicity in Karvina region
Main aim is to explore by experiments and calculations the dynamic behaviour of technological
structures and buildings that are under non-stationary dynamic loads by technical seismicity,
especially by seismicity induced by mining activities in the Karvina region. Measurements at
solitaire permanent stations are performed and also some short-term measurements were realized.
Surface geodetic measurements for study of sinking effects during initial periods of underground
mining are realized and new methods for joint interpretation of geodetic and geophysical data
are developed.
-
Development of measurement methods and interpretation methodologies
This topic results from joint research theme with prof. Lyubushin from the Institute of
Physics of the Earth, Russian Academy of Sciences, Moscow (e.g. using of wavelet transform
for seismological studies). Also, using of historical mine as natural laboratory for research
of new methodology for geomechanical measurements is part of this topic.
Development of special instrumentation for geophysical measurements, measurements and interpretation
of technical seismicity, and operation and interpretation of the geodetic and geophysical measurement
for shallow depths are other activities of the department.
Important scientific achievements
- Seismicity of northern part of the Moravo-Silesian Region
Natural seismicity is since 1993 very low. Almost 100 local microearthquakes were detected at
solitaire seismic stations of the Institute of Geonics AS CR; some of them were successfully
located. In region under discussion, seismic manifestations generated by mining induced seismicity
in Upper Silesian Coal Basin (both Karvina and Polish parts), Legnica-Głogow Copper District and
Lubin Copper Basin are detected. For example, during year 2007 14 rockbursts from Ostrava-Karvina
Coal Basin were recorded having the local magnitude span ML = 2.0- 2.8 and two were felt
on the surface with macroseismic intensity I0 = 2.0.
- Visualization and animation of a 3D regional velocity
model (northern Moravia and Silesia)
Using data from seismic refraction measurements 1D shallow velocity model was for the first time
established. For the determination of velocity-depth function along a short refraction profile, the
classical Wiechert-Herglotz method was used. This method seems to be a robust method of computing
simple vertically inhomogeneous models of shallow structures, as far as the observed travel-time
curve is sufficiently smoothed. The model is characterized by relatively low superficial velocity
vP ~ 4.5 km/s which is followed by steep increase of velocity vP ~ 5.8 km/s
to a depth of about 1.5 km.
The 3D velocity model based on data collected within years 2000 - 2009 was set up by means of seismic
tomography and is valid only for the territory of Northern Moravia and Silesia. The research issues
from reinterpretation of data from international and local seismic field experiments, records from
permanent and temporary seismic stations. Records of quarry blasts, mining induced seismic events
and local microearthquakes are used. For better inspection of the calculated model within the space,
special software packages were applied for the purpose of its visualization and animation.
- Analysis of long-period microseisms
The research of mutual link-up with long-period microseisms (T = 4-8 s) and current meteorological
situation in the broad area of European continent. Observation of the microseisms amplitude level
is based on long-term series of observation and their changes in dependence on the season of the
year and the position of atmospheric pressure configurations above oceans and continents. First
results are related to two strong windstorms Kyrill and Emma which occurred in mid-January 2007
and at the turn of February and March 2008 have already been published.
- Surveying (geodetic measurements) in undermined area
Observing of development of subsidence depression with a view to irregularity in movement processes
and deformations that are evoked first of all by rock massif pattern is main goal. Partial goal is
observing of boundary of subsidence depression with special emphasis to determination of possible
next causes of slight vertical movements.
- Wavelet decomposition of wave patterns of seismic events
Partial aims are using of wavelet transform for signal filtrations, determination of optimal wavelet
base (according minimum of optimum entropy) and optimal levels for packet decomposition. Spatial
mapping to plan of the absolute values of wavelet coefficients is used for concise presentation of
the decomposed signal in time-frequency domain. Analysis of long-term seismological records and
multifractal analysis of long-term geomechanical measurements are partial subjects.
- Stability study of medieval Mine Jeroným
Distributed measurement system for evaluation of seismic load, changes of level of mine water,
developing of failures in rock massif, changes of underground spaces (deformation of spaces) and
changes of stress tensor in rock massif is gradually built in medieval tin mine. Today, almost 20
sensors are used. Single-board PC of seismic apparatus is used as base for control system.
Transmission via GSM network enables to control system and also to transfer measured data to
operative system at the Institute of Geonics. This system provides data for study of stability of
mine spaces, in which new museum is planed.
- Study of blast operations seismic effect and other vibrations generated in proximity during
driving of shallow underground constructions
Study of seismic effects that are generated by blasting operations or other manifestations of
technical seismicity, which are occurring in vicinity during driving of shallow underground
construction, is main goal. Vibration effects in urban areas in/above driven construction or
suburban tunnel are very representative examples that illustrate urgency of research because
damages of structure can occurred.
