Alunecările de teren ocupă 18% din suprafața Podișului Moldovei (areal colinar ce reprezentă 10% din suprafața țării, și peste 10% din populația României), reprezentând un fenomen cu caracter de hazard și risc pentru societatea umană și mediul acestei zone. Vârsta alunecărilor din acest areal este predominant holocenă, fără a se putea exclude vârsta pleistocen superioară a unora. Climatul uscat, atât în perioada holocenă, cât și astăzi a permis păstrarea în morfologie a unor evenimente cu magnitudini diferite, care arată în general o scădere către perioada actuală, și evoluția alunecărilor fosile prin reactivări ale cornișei sau ale masei alunecate. Pentru a se prognoza evoluţia şi frecvenţa temporală a fenomenelor de alunecare în acest areal este foarte importantă stabilirea unei curbe temporale de magnitudine-frecvenţă, care să îmbunătăţească actualul model de evoluţie şi să permită evaluarea hazardului la alunecări de teren, şi ulterior a riscului. Obținerea unei rezoluții temporale îmbunătățite este crucială pentru relevarea legăturii dintre intensitatea fenomenului de alunecare și schimbările climatice holocene, antropocene și viitoare. Prezentul proiect își propune utilizarea unor metode variate (datarea cu radiocarbon, datarea dendrocronologică a reactivării alunecărilor de teren, cartarea multitemporală utilizând imagini de teledetecție, catalogarea informațiilor istorice privind alunecările de teren și efectele lor, și cartarea lor) prin care să se poată releva cu o rezoluție mai bună curba de frecvență temporală a activității alunecărilor de teren în holocen și antropocen și modelul de evoluție al acestora. Această curbă, prin asociere cu inventarul spațial al alunecărilor de teren și susceptibilitatea spațială derivată din acesta permite estimarea hazardului la alunecări de teren, o etapă majoră pentru abordarea riscului la alunecări de teren pentru acest areal.

Landslides occupies 18% of the area of the Moldavian Plateau (a hilly area which represents 10% of the country, and over 10% of the population), being a hazard and risk for human society and the environment of the study area. The age of these landslides is predominantly Holocene, without being able to exclude some upper Pleistocene age. Dry climate, both during the Holocene period and today has allowed keeping the morphology of landslide events with different magnitudes, which generally show a decrease in magnitude to the current period, and the reactivation of fossil landslides at their scarps and landslide bodies. In order to forecast the evolution and temporal frequency of landsliding phenomena in this area is very important to establish a temporal magnitude-frequency curve, which will improve the current model of evolution and enable landslide hazard and subsequent risk assessments. An improved temporal resolution is crucial for revealing the link between the intensity of the landslide phenomenon and the holocene, antropocene and future climate change. This project proposes the use of various methods (radiocarbon dating, dendrocronological dating of lanfdslide reactivation, multi-temporal mapping using remote sensing images, cataloging information concerning historical landslides and their effects, and the mapping of these events) that can reveal with a better resolution the temporal frequency curve of landslides in the Holocene and Antropocene and their evolution model. This curve, in association with the spatial inventory of landslides and the spatial susceptibility derived from it, will allow the estimation of landslide hazard, a major step to address the landslide risk assessment for this area.

    Rezultate

    RO

    În privința rezultatelor estimate, dorim să cartăm şi să obținem date privind vârsta alunecărilor de teren pentru 30 de areale, distribuite spațial la nivelul întregului Podiș al Moldovei sub forma unui (R1) inventar spațial, pentru a putea genera un (R2) inventar multitemporal al alunecărilor de teren holocene și antropocene din Podişul Moldovei. Pe lângă cele două baze de date spațiale, se va produce și (R3) o curbă temporală de frecvență-magnitudine și (R4) un model conceptual al evoluției alunecărilor de teren din Podișul Moldovei pentru holocen și antropocen. Cumularea bazelor de date menționate cu modelul de evoluție și cu curba frecvență-magnitudine va permite crearea (R5) scenariilor de hazard al alunecărilor de teren, la nivel regional, pentru întregul Podiș al Moldovei.

    Regarding, the estimated results, we envisage the mapping and dating of landslide age for 30 representative areas, distributed all over the plateau, in order to create (R1) a landslide inventory with the age of the landslides, and further (R2) a multitemporal inventory of the Moldavian Plateau for the holocene and the anthropocene. Beside the two spatial databases, (R3) a temporal curve of frequency-magnitude will be produced, and (R4) a conceptual model of landslide evolution will be produced for the Moldavian Plateau. Mixing the two spatial spatial databases and the two conceptual models will allow the creation of (R5) landslide hazard scenarios, at the regional scale of the Moldavian Plateau.
