Tsunamis in the Greek Region: An Overview of Geological and Geomorphological Evidence

The Greek region is known as one of the most seismically and tectonically active areas and it has been struck by some devastating tsunamis, with the most prominent one being the 365 AD event. During the past decade significant research efforts have been made in search of geological and geomorphological evidence of palaeotsunamis along the Greek coasts, primarily through the examination of sediment corings (72% of studies) and secondarily through boulders (i.e., 18%). The published data show that some deposits have been correlated with well-known events such as 365 AD, 1303 AD, the Minoan Santorini Eruption and the 1956 Amorgos earthquake and tsunami, while coastal studies from western Greece have also reported up to five tsunami events, dating as far back as the 6th millennium BC. Although the Ionian Islands, Peloponnese and Crete has been significantly studied, in the Aegean region research efforts are still scarce. Recent events such as the 1956 earthquake and tsunami and the 2020 Samos earthquake and tsunami highlight the need for further studies in this region, to better assess the impact of past events and for improving our knowledge of tsunami history. As Greece is amongst the most seismically active regions globally and has suffered from devastating tsunamis in the past, the identification of tsunami prone areas is essential not only for the scientific community but also for public authorities to design appropriate mitigation measures and prevent tsunami losses in the future.

Encountering a divine dance of solidarity at the Zalongo Monument

In this article, a combination of travelogue, personal narrative, archival research and cultural analysis, I contemplate the Monument to the Heroines of Zalongo, a sculpture by George Zongolopoulos that stands in the western Greek region of Epirus. It commemorates the Dance of Zalongo, a mass suicide, or heroic sacrifice, of women and children in 1803. The legend of the dance and the monument inspired by it evoke contradictory perspectives on the national identity of Greece and of Greeks that stretch back to the founding of the modern nation: the externally directed view of the philhellenes, and the introverted perspective of the Romii. Seen as an international, philhellenic cause, a mass suicide, the Souliote women’s leap signified helpless women and children, and a nation, in need of rescuing. Seen as a national, Greek narrative, a patriotic sacrifice, the Souliote women’s leap showed female warriors filled with pride and self-determination. The Dance of Zalongo has had many lives: as a nineteenth-century media event that sparked an outpouring of literature and art, a twentieth-century lifeline to the old country for Greeks in the diaspora and a twenty-first-century cultural meme bolstering resistance to economic austerity. The Zalongo Monument, a site for pilgrimage where Greek cultural memory is infused in stone and resonant in the air, recreates the presence of the dance, letting us feel what it means to be free. Visiting the monument as a philhellenic foreigner, I ponder its power as a tribute to solidarity among those everywhere who are pushed to the precipice.

Optimizing the Knowledge on Residential Heating Characteristics in Greece via Crowd-Sourcing Approach

Households have been pointed out as a significant source of air pollution and climate change. In Europe, the 60% of energy used by households is for space heating. The present work focuses on improving the knowledge on residential heating characteristics in Greece. The full causal chain, from the appliances used to the pollutants emitted, is examined at thelocal scale. A crowdsourcing approach was followed for the collection of the necessary data for performing the emissions calculations. With the use of a Geographic Information System (GIS), dynamic maps were produced for each Greek region, providing the information produced in this study in gridded form. In terms of energy demands, it was found that Greece relies mainly on oil and biomass and secondarily on gas and electricity. The use of biomass burning as a main heating fuel is quite high inthe colder and rural areas, while it is popular as a secondary heating fuel inthe urban areas. The residential heating period in Greece lasts from October to April and it is even shorter in southern Greece. In terms of emissions, CO and PM10 had the highest values since they are related to biomass burning. NOx emissions are mainly emitted by the oil burned in boilers.

Stra.Tech.Man innovation, HRM and Perception of Educational Needs in Underdeveloped Business Ecosystems: The Case of Retail Sector Firms in Eastern Macedonia and Thrace

Innovation becomes widely perceived as the most significant ingredient of socioeconomic development, for all types of organizations, at all spatial levels. This study aims to examine how a specific category of business people understand the phenomenon of innovation in relation to the dimensions of Human Resource Management (HRM) and intra- and external business education and training. It explores in particular how the firms of a less developed regional business ecosystem perceive this triangle of innovation-education-human resources, what is their current image and how this comprehension evolves over the last years. Through field research in firms located in the Greek region of Eastern Macedonia and Thrace, we highlight these qualitative correlations between innovation, workforce management, training, and education. Our findings suggest that the “image” of these entrepreneurs to these issues lacks interpretive depth and practical cohesion, which is related to pathogenies caused and causing the overall relative socioeconomic underdevelopment in the region. The originality of this research derives from the presentation and analysis of specific firms’ and professionals’ perceptions of innovation, which are relatively far from the standards set by the corresponding modern scientific literature and practice.

High-resolution gridded extreme precipitation indices for the wider Greek Region

<p>The goal of this study is to create a high-resolution grid of precipitation indices for the wider Greek region using real data from meteorological stations for the 1980-2010 period. Under the risk of increased extreme events caused by climate change, it is important to be able to have a high-resolution gridded extreme precipitation indices in order to overcome the lack of density of observations in both time and space. The development of such a grid can be used to validate model outputs and inform decision makers to better mitigate the damage from extreme precipitation.</p><p>The first step of the analysis is to calculate the extreme precipitation indices based on daily observations derived from more than 100 meteorological stations covering a wide range of altitudes and spatial climate patterns existing in Greece. Thereafter, the extreme indices will be multilinearly downscaled to a 12-meter resolution grid. The geophysical parameters used in the downscaling procedure consists of altitude, latitude, longitude, slope, aspect, solar irradiance and Euclidian distance from the water bodies. The altitude information came from the highly accurate 12-meter resolution TanDEM-X Elevation Model, which is a product generated from the TerraSAR-X satellite mission data. The resulting high-resolution patterns will give insight of the spatial and temporal variability of extreme precipitation, over the complex terrain of the wider Greek region.</p>

Multipliers and impacts of active sport tourism in the Greek region of Messinia

Few studies on the economic impact of active sport tourism have been conducted, and these are limited to one sport. Multipliers, moreover, relate only to sport activities and not to sport tourist typologies. This article examines the economic impact of four activities (golf, windsurfing, horse riding and scuba diving) on income and employment generation in Messinia, a region in south-western Greece. Since no input–output tables are available at this local level, the ad hoc model was employed. Golf generated higher income and more employment units than the other activities, displaying all of the characteristics of a propulsive activity, a concept derived from the growth pole theory. Regarding typologies, primary sports tourists exhibit higher multipliers than tourists interested in sport in every case. The article, also, partially validates the general consensus that small tourism firms have higher total multipliers than their larger counterparts. Implications stemming from the results are discussed.

Profiling Small and Medium Enterprises' Innovativeness During Periods of Economic Crisis

The role of innovation as a vital driving force of entrepreneurship and economic development has been widely acknowledged. Especially in an era of economic turbulence, innovation can be seen as the only realistic strategy that can lead enterprises out of the crisis. Based on the innovation taxonomies identified in the Oslo Manual, namely organizational, marketing, process, and product innovation, a survey was carried out in a Greek region adapting the fourth Community Innovation Survey questionnaire in 43 SMEs, capturing the effects of economic recession on the firms' innovativeness, and drawing a profile of the entrepreneurship innovation in the region of Western Macedonia, Greece. By applying a strategic group's approach, the authors come up with some interesting findings concerning the type of SME innovativeness and results of innovation during a period of financial crisis.
