It is proposed to
perform a new set of temporary seismic experiments using portable
broadband stations in order to study several issues related to wave
propagation. The main objectives of these experiments which follow the
previous 1999 and 1997 experiments are the following:
 | to
identify the predominant directions of defracted waves at several
locations within the basin |
| to
identify the defracted waves generated during the forced vibration tests
at the model structures |
| to
explore the 3D structure of the basin |
| to
perform site effect studies |
The
experiments will be performed around the TST Site at the center of the
valley and in many locations within the whole valley. A second set of
underground explosion experiments is also foreseen within the context of
the aforementioned temporary seismic experiments.
An
example of the configuration of the past temporary seismic experiments (1997
& 1994) in the framework of
previous research projects is provided in the following figures.
