FIELD TRIP – May 18, 2018
Buzau Mountains are constituting a unit of the Curvature sector of the SE Carpathians, built mainly on Cretaceous (at the interior) and Palaeogene flysch deposits. The field trip’s focus will be directed towards high magnitude-low frequency landslides (deep seated, mainly dormant, with large reactivation potential) and their climatic and seismic triggers. Aspects concerning deep-focal seismicity, lito-structural conditioning, active and blind faults will be also discussed. The human impact on the environment will be emphasized through case-studies like road and reservoir construction. Morphodynamic mapping, landslide susceptibility and hazard scenarios, numerical and statistical models will be detailed through field examples.
FIELD TRIP – May 20, 2018
Buzau Subcarpathians are representing a hilly transition unit developed on Mio-Pliocene molasse deposits at the foothills of the Carpathians. The area is severely affected by a wide range of slope and channel processes, frequently interconnected, with a preparing/triggering potential enhanced by climatic and human-driven factors and more important, active seismicity (the intermediate-depth Vrancea seismic region generated throughout the last 300 years 12 earthquakes with Mw > 7, out of which 4 above 7.5 and 3 between 7.7 and 7.9). The focus of the field trip will be on the conceptual framework of single-to-multi-hazard and on the inter and transdisciplinarity characteristics of geomorphology within a multi-risk approach.
