  • Identifying optimal locations for mobile first aid facilities in Bucharest, accounting for seismic risk

    Author: Iuliana ARMAȘ, Dragoș TOMA-DANILĂ, Diana POPOVICI, Ruxandra MOCANU

    Abstract: In case of a major earthquake in the Vrancea area, Bucharest can be significantly affected
    (as it happened in 1940 and 1977). As highlighted by these events, the need for establishing mobile
    first aid facilities close to affected areas (deployment of medical containers or mobile hospitals) is
    expected to be of high importance for saving lives. In this research we identify the need of such
    facilities and the favorable locations, considering multiple earthquake scenarios. Our methodology is
    based on multicriteria analysis in which we use the SMCE module of the ILWIS geospatial program
    and take into account three indicators: (i) the estimated losses in terms of affected residential
    buildings and occupants, calculated for 3 earthquake scenarios, (ii) distances from buildings with high
    seismic risk levels (categories I and II) and from important traffic routes, and (iii) road network
    connectivity loss after a major earthquake. The results identified the central and peripheral area as
    having complex issues and the need for future analyzes at the neighborhood level.

    Keywords: first aid, emergency management, earthquake, Bucharest, disaster risk.

  • A short review and selection of soil erosion models

    Author: Mara NILCA

    Abstract: The article gives a brief review of the related literature concerning soil erosion by surface
    water flow and provides an outline of several currently available models. They are analyzed in terms
    of their model structure and spatial and temporal resolution. The focus was on selecting a number of
    three model approaches that potentially could be applied to the upper and middle sectors of the
    Prahova River Valley.

    Keywords: soil erosion models, RUSLE- 3D, USPED, SPL, Prahova Valley.

  • InSAR digital terrain models for mining areas based on Sentinel-1 imagery. A case study in Căliman area

    Author: Mihaela GHEORGHE, Andrei-Ioan VODĂ MARC

    Abstract: Although not intended at first, SAR satellite technology has been used for digital terrain
    models (DTM) generation and displacement monitoring for the last 30 years starting with the launch
    of the first RADAR imaging satellite by the European Spatial Agency (ESA), ERS-1. Currently, there
    is a suite of satellites available for these applications, with ESA’s Sentinel-1 being one of the most
    accessible and exploited by scientists due to its wide and free of costs availability. The C-band repeatpass
    interferometer is considered unsuitable for DTM generation due to its acquisition geometry. In
    this study, a DTM based on Sentinel-1 imagery for the former sulphur quarry mine in Căliman
    Mountains is derived in order to demonstrate the potential of the dataset for time and cost effective
    monitoring of large areas.

    Keywords: InSAR; Digital terrain model, mining, Sentinel-1.

  • Bucharest Drivers’ Perception of Navigation Apps and their Impact on Road Traffic

    Author: Ruxandra MOCANU

    Abstract: Bucharest is one of the most affected cities in the world in terms of road traffic congestion
    and under these conditions, drivers are constantly looking for new strategies to help them cope with
    daily traffic. They are increasingly relying on more on navigation applications installed in their
    smartphones with GPS capabilities. This research aims to investigate drivers’ perception of the way
    they use navigation applications and their purpose, especially Waze, their perception of the impact of
    these applications on traffic and the city or even on socialization (socialization through the application
    or the socializing effects of the application itself). The study conducted in 2018 reveals the positive
    perception of the impact that the application has and highlights its new affordance, drivers using it as
    a socialization tool, a utility that was not initially intended.

    Keywords: navigation applications, mobility, traffic congestions, road traffic.

  • P. Krugman’s Core-Periphery Model. Case Study: The Tourist Demand on the Romanian Seaside

    Author: Ruxandra-Luminița GHEORGHE

    Abstract: Krugman's model is a new approach for Romania, even more applied to the Black Sea
    seaside. The tourist demand in such a way reveals the relations not only economic, but also of another
    nature between the core and the periphery. The data clearly show that this model is a forceful one,
    applicable not only to the Romanian seaside, but also to the region, country or continent, and its study
    can reveal very interesting conclusions: the influence of the core on the periphery, how the North and
    the South interact in the chosen model and how seasonality affects seaside tourism.

    Keywords: Krugman, core-periphery, tourist demand, seaside, seasonality.

  • Review of Geodiversity and Geoheritage related sessions at the European Geosciences Union General Assemblies

    Author: Maria BOSTENARU DAN

    Abstract: Sessions related to geoheritage have been held under different convenorships and titles
    since 2012 at the European Geosciences Union General Assembly in Vienna. 2020 was a special year,
    since the session was held online. The author participated with a contribution in 2019 and without one
    in 2020, and it was an occasion to compare a physical session with oral and poster presentations and a
    splinter meeting to a digital session.

    Keywords: geopark, Chaîne des Puys, Piedmont, rural landscape, geoproduct, agricultural landscape, natural heritage.

  • Report from the first workshop of International Permafrost Association Action Group Rock glaciers inventories and kinematics

    Author: Răzvan POPESCU

    Abstract: The recent initiative to standardize the mapping and monitoring of rock glaciers around the
    world resulted in the organization of the First Workshop of the Action Group Rock glaciers
    inventories and kinematics, in Evolene, Switzerland. The participants focused to discuss in detail and
    debate several issues to be introduced in a new version of a guidelines document regarding rock
    glaciers inventorying. This paper discusses the development of the field trips and working sessions of
    the workshop.

    Keywords: rock glaciers, mountain permafrost, action group, workshop, International Permafrost Association.
