Chapter
The chapter provides a comprehensive overview of natural hazards but does not cover man-made hazards. From a theoretical point of view, it analyses the relationship between natural hazards and risks, the physical basis for the development of hazards and the consequences of their effects. It also quantifies the human and financial aspects of hazards...
Chapter
The extraterrestrial impacts on our planet can be broadly divided into two groups. The first is the activity of the Sun, which is the source of life on Earth. The second is the impact of meteor showers, which cause impacts, or impact phenomena, which form small or large circular symmetrical craters. This compilation describes the physical backgroun...
Chapter
The chapter deals with the development of four natural hazards: volcanism, earthquakes, the most associated tsunami and slope mass movements and their damage and mitigation options. For each of these hazards is a sketch of how they occur, an explanation of their geographical location, a calculation of the intensity of their activity and an assessme...
Chapter
The chapter deals with the issues of water abundance and water scarcity. In general, too much water means the dangers of increased water runoff and discharge. In the first part, the different types of floods and inland excess water are summarised, along with their causes and the human and financial consequences of this natural hazard. It also deals...
Chapter
In addition to a general description of climate change, the chapter summarises the natural hazards associated with inland ice sheets, glaciers, oceans and permafrost. While these flows are changing significantly due to climate change, they are often not considered natural hazards because they do not involve human or material sacrifice. However, the...
Chapter
The consequences of meteorological hazards include an increase in the number of heatwaves, extreme storms, climate extremes in general and changes in hydrological processes. The chapter summarises many types of meteorological hazards and their negative consequences. These increasing numbers of hazards are grouped into three categories: extreme temp...
Article
The Deliblato Sands is among the largest uniform dune fields of Europe, with a very pronounced topography reflecting extensive past aeolian events. Although lacking numerical age data, previous researchers have hypothesized various periods of dune formation. Our research goals were to map the main morphological units of the Deliblato Sands, and to...

Full-text available
The luminescence sensitivity of a sample is the luminescence intensity measured in response to unit radioactive dose. Sensitivity is by no means a stable parameter, it might change during measurements, or in nature as well. The primary or natural magnitude of luminescence sensitivity is basically determined by mineralogical background (number of cr...

The Zemun settlement on the northern outskirts of Belgrade has experienced a number of landslides in the last three decades, endangering buildings and roads, and claiming human lives, par...
Chapter
The Great Hungarian Plain is the largest macro-region in the Carpathian Basin. In the chapter, the evolutionary models of the region will be described, and also a general picture will be drawn on the evolution of its lithology, morphology, hydrology, climate and vegetation. In a meso-scale, the general descriptions of landscape parameters will be g...
Chapter
The potentials and hazards of surface and subsurface waters are very important elements of the Hungarian environment. The geographical location of the region (e.g. basin-like character, continental water household) determines the possibilities (e.g. great subsurface water bodies) and the hazards (e.g. extreme water regime of the rivers, flood hazar...
Chapter
This chapter describes the hierarchic system of the Hungarian landscape units and its structure. The smallest unit is the ecotope, and the group of ecotopes forms the micro-region, which constitute meso- and macro-regions. This system is the basis of the regional description of Hungary, introduced in Part II of the book. Based on the accepted Hunga...
Chapter
The members of the North Hungarian Mountains are built of mainly Miocene andesitic volcanoes. They were strato-volcanoes with single volcanic vents, and during their evolution calderas developed. The only one exception is the Zemplén Mountains in northeast, where centro-labial volcanoes developed. In the macro-region the Bükk and Aggtelek Mountains...

Full-text available
The Little Hungarian Plain is situated in the north-western part of the Carpathian Basin; it is similar to the Great Hungarian Plain, as it is also a sinking area, though with a much smaller territory. Its material consists of several 100-m-thick loose fluvial sediments, and along the rim of the region aeolian material also deposited. The main char...
Chapter
It is difficult to sum up the main characteristics of the West Hungarian Border Region, as it constitutes of meso-regions with quite different characters and origin: Palaeozoic mountain ridges of the Alps stretch into the basin and pebble sheets connected to them. The meso-scale description of the region gives detailed analyses on this variegated r...
Chapter
The climate of the Carpathian Basin reflects the combined characteristics of the neighbouring regions. Despite of the small area and the modest orographic differences of the country, the climate elements (e.g. solar radiation, temperature or precipitation conditions) have distinctive spatial and temporal characters. The result of climatic measureme...
Chapter
The Transdanubian Hills in the southern-central part of Hungary consists of hills built of fluvial and aeolian material, though some mountain blocks built of Palaeo- and Mesozoic marine sediments (Mecsek Mts., Villányi Mt.) are also represented. The latest ones have small area, but they have great importance as their uranium and black coal reserves...
Chapter
In this chapter, the palaeo-geographical changes of the central part of the Carpathian Basin are described, since the Palaeozoic until nowadays. It analyses the evolution of the landscape based on plate tectonics, besides the main influencing factors of palaeo-geographical forms and processes are also studied in connection with climate and vegetati...
Chapter
In this chapter, the soils of Hungary are grouped following the widely accepted Hungarian genetic and pedological classifications. The application of the FAO system has not been realised yet (though such map is presented in the chapter), and it will be probably published in 2016/2017. However, probably the change from the genetic to FAO system will...
Chapter
The species composition of the vegetation in the Carpathian Basin is determined by the climate, relief, lithology/soil and hydrological conditions. Two main zonal vegetation types appear in Hungary: the zone of deciduous forests, which is dominated by oak and beech (especially in hilly and mountainous areas), and its most widespread forest type is...
Chapter
The Transdanubian Mountains mainly consist of Mesozoic carbonate sedimentary blocks, but young volcanic elements also appear in the region. The main character of the macro-region is determined by limestone and dolomite covered by younger sediments, as they influence the rate of (weak) karstification and the type of vegetation, which is also influen...
Book

The spatial and temporal alteration of the vegetation was monitored by detailed coenological investigations and...
Chapter
The landforms of granite weathering in the Velence Hills are unique in Central Europe. Through intensive weathering since the end of the Permian the exposed granite mass was transformed to saprolite. Weathering combined with sheet wash worked on the Eocene andesite too and resulted in heavy denudation. Since the Late Tertiary tectonic movements als...

In Hungary, wind erosion is one of the most serious natural hazards. Spatial and temporal variation in the factors that determine the location and intensity of wind erosion damage are not well known, nor are the regional and local sensitivities to erosion. Because of methodological challenges, no multi-factor, regional wind erosion sensitivity map...
Article
Full-text available
Artificial barriers significantly disturb the landscape unit. Roads split the contiguous landscape units, thus basically modi fying their ecological characters. The more artificial barriers are constructed in the landscape, the more fragmented it is. Theref ore, the contiguous landscape unit is divided into two or more patches, weakening resilience...

From an economic aspect, landscapes have different, direct and indirect values, or according to Naveh (1984), hard and soft values. Most of the hard values can be measured well, e.g. the values of the direct economic benefit, such as the NPP or the ecological value used in landscape ecology (Marks et al. 1989). From economic considerations, some au...
