“…In the past decade an increasing number of scientific works have addressed research questions about scoria cone degradation. Various approaches have been suggested to define and measure volcanic cone dimensions [10,[35][36][37][38][39][40][41][42]. These methods advocate measuring cone morphometric parameters to generate discrimination diagrams, as well as using volcanic slope angles as a key physical parameter to indicate typical erosion paths and relative erosional trends over time for scoria cones (on a scale of up to millions of years).…”

UNESCO promotes geoconservation through various programs intended to establish an inventory of geologically and geomorphologically significant features worldwide that can serve as an important database to understand the Earth's global geoheritage. An ultimate goal of such projects globally is to establish geoparks that represent an integrated network of knowledge transfer opportunities, based on a specific array of geological and geomorphological sites able to graphically demonstrate how the Earth works to the general public. In these complex geoconservation and geoeducational programs, the identification of significant geological and geomorphological features is very important. These are commonly referred to as 'geosites' or 'geomorphosites', depending on whether the feature or processes the site demonstrates is more geological or geomorphological, respectively. The Kingdom of Saudi Arabia is an extraordinary place due to its arid climate and therefore perfect exposures of rock formations. The Kingdom is also home to extensive volcanic fields, named "harrats" in Arabic, referring particularly to the black, basaltic lava fields that dominate the desert landscape. Current efforts to increase awareness of the importance of these volcanic fields in the geological landscape of Arabia culminated in the first proposal to incorporate the superbly exposed volcanic features into an integrated geoconservation and geoeducation program that will hopefully lead to the development of a geopark named, "The Harrat Al Madinah Volcanic Geopark" [1].Here we describe one of the extraordinary features of the proposed Harrat Al Madinah Volcanic Geopark, namely a steep lava spatter cone formed during a historical eruption in 1256 AD.

This report covers the research activity belonging to the topics of IAVCEI that has been carried out during the past four years period between 2007 and 2010. The most significant results were obtained in the geochemical, petrological and structural investigation of the young (mainly Miocene and Plio-Pleisticene) volcanism in the Carpathian-Pannonian Region, and in the complex study of the upper mantle xenoliths beneath this region. The research topics and new results will be presented according to the following classification: Palaeozoic and Mesozoic intrusive magmatism in the Carpathian-PannonianRegion including the Variscan granitoids and the Mesozoic Ditrȃu alkaline complex.2. Paleogene-Neogene and Quaternary volcanism in the Carpathian-Pannonian Region.3. The upper mantle and lower crust beneath the Carpathian-Pannonian area based on the study of xenoliths 4. Studies based on international co-operation.

“…The problem in the calculation of the cone height in the case of a steeply dipping basal plane has been described by Favalli et al (2009). However, the shallow-dipping plane characterizing the study area (less than 5u) allows for modeling the basal plane of the cone as a flat surface.…”

Abstract. The present research examines the measured morphometric values of monogenetic cinder cones in the Tolbachik volcanic field, Kluchevskaya volcanic group, Kamchatka. The cones were measured from digital elevation models (DEMs) derived from satellite data (ASTER, ALOS PALSAR, and SRTM) and from digitized topographic maps. GPS measurements of 85 locations were performed in the field to provide geodetic reference for DEM processing and to assess the accuracy of the DEM. A methodology for morphometric measurements on a DEM is proposed. The morphometric parameters derived from a DEM include the main characteristics that control the rate of degradational evolution of the cone, namely height, width, and slope. The measured morphometric values were compared and accuracy assessment was carried out. Our study analyzes the morphometric values of four recent cinder cones formed during the last basaltic eruption in 1975-1976 and five older cinder cones formed during the last 2000 years. We show that morphometric values obtained from a DEM are affected by the resolution change, and characteristics of the same cinder cone may vary among DEMs of different resolutions. Our results indicate that the morphometry of the cinder cones can be well characterized by a DEM derived from remotely sensed data. The calculated morphometric parameters showed a correlation with the spatial resolution of the DEM and relative age of the cinder cones. All DEMs studied (including coarse-resolution SRTM) were found to provide reliable morphometric parameters, although the calculated values varied as a function of spatial resolution.Résumé. Dans la présente recherche, on examine les valeurs morphométriques mesurées à partir des cô nes de scories monogéniques dans le champ volcanique de Tolbachik (groupe volcanique Kluchevskaya, Kamchatka). Les cô nes ont été mesurés à partir de modèles numériques d'élévation dérivés de données satellitaires (ASTER, ALOS PALSAR et SRTM) et de cartes topographiques numérisées. Des mesures GPS ont été acquises sur le terrain sur 85 sites à titre de référence géodésique pour le traitement du MNE de même que pour évaluer la précision du MNE. On propose une méthodologie pour dériver des mesures morphométriques d'un MNE. Les paramètres morphométriques dérivés d'un MNE incluent les principales caractéristiques qui contrô lent le taux de dégradation du cô ne : la hauteur, la largeur et la pente. Les valeurs morphométriques mesurées ont été comparées et une évaluation de la précision a été réalisée. Dans cette étude, on analyse les valeurs morphométriques de quatre cô nes de scories récents formés lors de la dernière éruption basaltique en 1975-1976 et de cinq plus anciens formés au cours des 2000 dernières années. On montre que les valeurs morphométriques obtenues d'un MNE sont affectées par le changement de résolution et que les caractéristiques d'un même cô ne de scories peuvent varier selon les différentes résolutions du MNE. Les résultats démontrent que la morphométrie des cô nes de scories peut être caractérisée ...
