| Zusammenfassung |
This study simulates automatic event detection and location performance of a
micro-earthquake network centred around a future power plant site in
Finland, Fennoscandian Shield. Simulation of the event location capability
is based on a relationship derived between event magnitude and maximum
detection distance. Azimuthal coverage and threshold magnitude are computed
for different station configurations and the results are presented as
contour maps.
An optimal configuration of ten seismograph stations is proposed for further
on-site survey. The network fulfils the preconditions of automatic event
location capability down to ML 0.0 and azimuthal coverage better
than 180° within 25 km radius from the study site. Annual number
of earthquakes (ML ≥ 0.0) detected by the network is estimated to
be 2 and 8 within 25 and 50 km radius from the power plant site. |
