| Zusammenfassung |
| In this paper we examine the Coulomb (static) stress pattern following the
two moderate magnitude earthquakes in NW Slovenia during 1998 and 2004.
These earthquakes ruptured patches of the NW-SE striking Ravne fault that
crosses the Krn Mountain. The objective is to investigate the seismicity
patterns for this area of Slovenia given that future earthquakes may be
triggered as a result of stress changes along neighbouring faults. Our
findings include: a) stress levels have increased along the active Ravne
fault for all models discussed b) stress levels have decreased along the
active, NW-SE striking Idrija fault and c) stress levels throughout the
crust have increased along the E-W direction but have decreased in the N-S
direction (stress shadow effect). We also mapped a better correlation of the
off-fault aftershock locations with stress maps incorporating the regional
stress field. |
