-    * A cluster of epicentres of weak earthquakes between the towns of Langenlois, Gfohl, Ybbs an der Donau and Melk (see **[[dbz:diendorf-boskovice_fault#Observed seismicity]]**) suggest possible connection with southern Diendorf fault (sections DF_1, 2, 5 and 6). However, the causal links are unclear as the cluster shape (possibly affected by poor accuracy of location) allows for different conclusions. In the area of southern Bohemian Massif the increased seismicity seems to be characteristic. Some observations suggest that unmapped NW-SE striking faults may be responsible for at least part of these earthquakes (see site **[[dbz:diendorf-boskovice_fault#Schönbühel a.d. Donau: Cross-structure|Schönbühel a.d. Donau]]** as an example). The concerned sections of DF are admitted to take part in this deformation but activation of large segments by a single earthquake seems unlikely.

     * To the north of Langenlois the low number and magnitude of historical and instrumental earthquakes and their low spatial correlation with fault line do not allow affiliation of seismicity to any known structures.
     * Rare local observations of soft sediment deformation structures are interpreted as due to paleoearthquakes with minimum intensity of 6-7° (sites **[[dbz:diendorf-boskovice_fault#Lechovice: Cross-structure and inferred paleoearthquake|Lechovice]]** and **[[dbz:diendorf-boskovice_fault#Tasovice: Observed sealing strata and inferred paleoearthquake|Tasovice]]**). The source of these hypothetical earthquakes is entirely unknown and they are not necessarily related to Diendorf fault. In case of epicentre located close to observation sites, the minimum magnitude of Mw=5 should be considered.
