Cli mate de te rio ra tion of the Lit tle Ice Age was mani fested in the most spec tacu lar way in the gla ci ated high moun -tains, but it should also be ana lysed in term of a cli matic con cept. Spa tial varia tion in LIA cli mate is il lus trated also in non- glaciated ar eas of the North ern Hemi sphere in a broader con tex. Ex treme cli matic events were forc ing fac tors for moun tain slope de for ma tion by geo mor phic pro cesses in the High Ta tra Moun tains. The old chroni cles, li che no met ric dat ing of land forms and la cus trine sedi ments are used to de ter mine the be gin ning of “Lit tle Ice Age – type events” (about AD 1400) and its end (about AD 1920).

Merapi Volcano
Opis:
Merapi Volcano in Central Java, Indonesia, has a high eruption intensity that triggers landscape changes in the form of a river channel evolution. In this paper, the spatial change of river valleys under the influence of sediments deposition in the fluvio-volcanic system is investigated. The data were collected by employing observation, remote sensing image interpretation, literature study and documentation of data from several agencies. The data were analysed using the spatial approach supported by geographic information system (GIS) and remote sensing. The results show that there are many palaeochannels related to fluvio-volcanic processes from the southern to the western sectors of the Merapi volcanic foot. Palaeochannels are mainly distributed next to the main river valleys. This condition correlates with the contributions of the Merapi eruptions. The palaeochannel distribution patterns cluster radially following the distribution pattern of the river valleys. The process that plays the most important role in the evolution of palaeochannels is the deposition of lahar. In sum, this research shows that volcanic activities over a long period of time have provided great and important contributions that have driven the landform evolution. The various changes that occur also reveal the unique morphological characteristics, showing the influence of the volcanic processes.
