Neotectonic preconditions for landslides in Moldavia

Abstract

In Moldavia the sedimentary upper horizon of Cenozoic is usually displaced along fault-lines of SW and SE direction. Tectonic impulse at the platform's margin coicided with the 3rd Late Pliocene stage of large charriage formation in the Carpathians; it caused many normal and strikeslip faults and overthrusts with gently sloping thrust plane. Most landslides are restricted to those tectonic zones. Clusters of landslides are also found within mobile tectonic zones which had been delimited during the mapping of a paleogeographic marker surface - the planation surf ace dated from the Middle Pliocene. A few landslides are older than the Late Pliestocene - Holocene, they were probably formed along fault-lines due to earthquakes or on slope due to erosion of its base.
