“…Свлачищни процеси се наблюдават сравнително далече от района на проучване (Frangov et al, 2011;Berov et al, 2020;Ivanov et al, 2022) и не застрашават сигурността на проектираното съоръжение както при строителството, така и при експлоатацията му. Според направената оценка на риска от природни бедствия от Францова (Frantzova, 2021) крайният резултат показва ниски и много ниски нива на геоложки риск и не се очакват значими щети в случай на настъпване на свлачища и земетресения в района на община Приморско.…”

The present study is related to the preparation of a project for the construction of a fishing port for small vessels in the area between the mouth of the Dyavolska River and Cape Kyupria (SE Bulgaria) with the aim of protecting the water area from dangerous wave loads, geological and meteorological impacts and creating conditions for safe docking, service and accommodation of the fishing vessels. The geological structure, geomorphology and physical-geological phenomena in the water area of Primorsko Fishing Port in the southern part of Cape Kyupria have been clarified. An engineering-geological project was prepared, the physico-mechanical indicators of the construction soils and the geotechnical characteristics of the ground base were determined. A complex package of scientific and engineering-geological methods was applied during the implementation of the project. Based on the obtained scientific and applied results, recommendations were made to the Municipality of Primorsko in connection with the construction of the port. The foundation conditions of the designed wharf with a walled pier are favorable for the construction of the wharf with gravity hydrotechnical facilities.

“…Coping Capacity is the collective term used to describe the methods employed by individuals or organizations to utilize their existing resources/capabilities (before, during, and after the occurrence of a disaster) to effectively manage the associated adverse consequences [44]. While vulnerability primarily directs attention toward communities and individuals, coping capacity serves as a measure encompassing prevention/mitigation, preparedness, response, and recovery efforts [45]. Several formulas have been developed to include these elements in evaluating risk, which can be used in the development of risk matrices.…”

The changing and intensifying landscape of global, national, and local disaster risks, driven by socio-political, environmental, and technological shifts, underscores the critical need for risk assessment by international agencies and governments. The Risk Matrix, introduced in 1995, has been widely used for risk assessment in different contexts, lauded for its simplicity and effectiveness. This model relies on the core risk components of consequence and likelihood, making it a favored tool for risk managers. To enhance the precision of risk assessment, various adaptations and extensions of the risk matrix have emerged; while some indirectly address resilience aspects, none explicitly integrate resilience into the matrix. This paper explores the risk matrix and its extensions, advocating for the inclusion of resilience in risk assessment. It introduces an empirical approach to quantify resilience, through a survey targeting small and medium-sized businesses in Southern Ontario, Canada. By developing two types of risk matrices—one with resilience considerations and one without—our work demonstrates how resilience alters risk prioritization, highlighting the importance of preparedness. This research underscores the pivotal role of resilience in risk assessment and urges its explicit integration into risk matrices to enhance accuracy and efficacy. Through practical examples and empirical data, the paper builds a compelling case for the central role of resilience in modern risk assessment practices.

An assessment of the landslide risk (Rls) for the territory of Bulgaria by administrative districts has been made by combining the vulnerability (V) and landslide hazard (Hls) maps. Landslides are a significant part of geological hazards and are widespread throughout the country. In order to assess the landslide risk for the territory of Bulgaria, it is necessary to take into account not only all landslides for a given region, but also its vulnerability, and thus to assess the level of landslide risk for this region, Rls = f (V, Hls). Landslide risk is determined by a risk matrix, using selected indicators and weighting coefficient of vulnerability and landslide hazard. Assessing the vulnerability of a region subjected to geological hazards is a key component of risk assessment. These include the exposure of infrastructure, industrial facilities and production capacity, residential buildings, regional GDP per capita and potential for human disability (defined by population density in the district). The data used is combined to create a map showing the vulnerability of each administrative district. Indicators of population density, GDP, length of road and railway networks and number of residential buildings were used to assess the vulnerability. The landslide hazard in each administrative district is determined by the intensity of landslide processes in the district, depending on the level of their activity and the affected area. The normalized (distributed) hazard of landslides for an administrative region is given depending on the area of the given administrative region. Landslides are categorized as active, potential and stabilized. The results express the weighted average hazard. Landslide hazard is rated from 1 to 5, where 1 means no landslide hazard and 5 means that landslide hazard has a very high intensity (very high hazard). The high degree of landslide hazard in turn leads to possible economic losses, social and environmental consequences (landslide risk). The intensity (level) of landslide vulnerability, hazard and risk is assessed as very low, low, medium, high and very high, and is shown on the relevant maps.
