“…The geological setting of the Ajanta Caves was characterized recently by Ansari et al (2014). The Ajanta Caves are carved in a compound basalt flow of the Ajanta Formation belonging to the Sahyadri Group of the Deccan Traps.…”

“…The other important geological feature is the rocks, in which the Ajanta Caves were excavated. These are the flood basalts (traps) of the Deccan Plateau (Ansari et al, 2014) that were emplaced at the Cretaceous-Paleogene transition (Courtillot & Renne, 2003;Baksi, 2014). These basalts are of outstanding interest because of two reasons.…”

“…These seem to be enough to judge about the Ajanta Caves as a local geomorphosite. Finally, rockfall hazard in the Ajanta Caves was explored recently by Ansari et al (2014). As this phenomenon was proven possible, the engineering geological feature (according to the classification of Ruban (2010) and Ruban & Kuo (2010)) should be recognized.…”

International development for the both geoconservation and geotourism requires attention to all kinds of (potential) geological heritage. The Ajanta Caves (western Maharashtra, India) is a famous cultural object consisting of 30 caves carved in the Deccan Traps and inscribed to the UNESCO list of the World Heritage Sites. Its examination permits to indicate four geological features, which are the artificial caves themselves (these mark geological activity of the man in the historical past), the end-Cretaceous floot basalts (these demonstrate the emplacement of Large Igneous Province and the relevant palaeoenvironmental catastrophe), the gorge of the Waghora River (this is peculiar landform resulted from the river erosion of hard rocks), and the rockfall hazard (this is an interesting engineering geological phenomenon linked to the caves construction/maintenance). Geological heritage value of these features is argued. Unfortunately, there is not any geotourism activity at the Ajanta Caves presently. The content analysis of the principal on-line resources (web pages) devoted to this cultural site reveals the absence of sufficient geological information that would facilitate geotourism. Generally, judgements about the Ajanta Caves and the other similar sites in the geological dimension permit to consider the wide spectrum of the geological heritage. They also highlight some extra opportunities for geotourism, which can benefit by its development at cultural sites with thousands of visitors.

“…The dynamic processes of a rockfall event may be free-fall, bouncing or rolling, depending on the geometrical features and mechanical properties (friction, roughness, rolling resistance, restitution characteristics, etc.) of the slope and rock blocks (Ritchie 1963;Agliardi and Crosta 2003;Alejano et al 2010;Ansari et al 2014). As the profile changes, two or more of the rockfall modes may also be observed, depending on the different dynamic processes.…”

The study area, which will be open to tourism in Kusadasi (Aydin), has steep and high cliffs on the Aegean coast in Turkey. Flysch is the main lithological unit and consists of alternating sandstone-claystone-marl sequences. Some sliding and rockfall problems have occurred in the area in the past, so potential geological hazards need to be investigated to ensure the safety of tourists. The aim of this study is to mitigate geological hazards by recommending engineering solutions, which will ensure the continuation of the nature-friendly appearance of the slopes. To accomplish these tasks, a geological survey was performed. It involved gathering information on rock discontinuities by means of scan-line surveys and collection of rock samples. Furthermore, in situ and laboratory tests were also carried out. The data collected from the field and laboratory test results were used to perform slope stability and rockfall (2-D and 3-D) analyses for different slope conditions along 43 profiles. Based on the analyses, rockfall was found to be the main slope instability problem in the study area. Under the light of these studies, rock removal, drainage, greening (vegetation), filling of caverns, protective wall building and erosion prevention are offered as remedial measures.

“…Geomatics, Natural Hazards and Risk, 2015http://dx.doi.org/10.1080/19475705.2014 For the systematic identification of rockfall prone slopes, a rating system should be used to speed up the analysis of potentially dangerous rockfall slope. Considering the relevance of the topic, this paper identifies rockfall hazard prone zones with the help of Rockfall Hazard Rating System for India (RHRSI) ) and focusing on the consequence of failure (Bunce et al 1997;Fell et al 2005;Roberds 2005;Ansari et al 2014). …”

Construction of railways, highways and roads around steep slopes is a challenging assignment and require special investigations by geologists and geotechnical engineers that help to identify critical slopes. Rockfall Hazard Rating System for India (RHRSI) is a modified scheme for Indian subcontinent and used to define overall stability of slopes in mountainous region or rock cut slopes. Once this rating system identifies critical zones, proper protection measures can be applied to prevent rockfalls. In this article, RHRSI is adopted to identify slopes, prone to rockfalls so that proper preventive measure can be proposed to mitigate loss. State Highway-72 (SH-72) connecting Poladpur to Mahabaleshwar, is an important transportation corridor supporting high vehicle traffic within the wellknown tourist area is chosen for rockfall hazard rating. Field observations show that up to 15 km corridor from Mahabaleshwar town has frequent rockfall problems with two most rockfall locations situated at about 12 and 6 km from Mahabaleshwar town. Also, an attempt has been made to focus on riskconsequence analysis for rockfall locations. To this aim, the RHRSI is applied to SH-72 corridor on two locations which are identified as very prone to rockfall hazard.
