“…5). This kind of survey permit also to define boulder volumes, imbrication, a-axis azimuth (Table 1) and to hypothesize their pretransport position (Pignatelli et al, 2010;Mastronuzzi and Pignatelli, 2011). Digital survey were performed using a Leica Scanstation 2 able to scan the landscape up to about 300 m from the laser-beam generator in function of the reflectivity of the scanned object (Fig.…”

An extended berm of calcarenitic boulders is recognisable at Punta Saguerra, few kilometres south of Taranto (Apulia, Italy) while isolated boulders are sparse in other near localities. The berm is at 2-5 m above present sea level (a.p.s.l), on a rocky headland gently sloping toward the sea; it is separated from the coastline by a large terrace. A detailed study of its stratigraphy and its morphology has been performed in order to define its depositional mechanism; in particular, integrated DGPS and Laser Scanner surveys have provided precise details of each boulder: position, size and distance from the shoreline. The accumulation is constitute of boulders up to 30 tons, which locally are arranged in rows of embricated patterns. The surfaces of the biggest boulders are characterised by biogenic encrustations and by solution potholes that indicate their intertidal/adlittoral/spray zone provenience. Based on direct observations of each boulder (size, shape, weight and long axis azimuth), together with hydrodynamic equations it is possible to hypothesize the extreme event-geodynamic or meteorologicalwhich was responsible for this singular accumulation. AMS age determinations on Vermetid sp. sampled on boulder surfaces and chronicle suggest that the accumulation may be attributed to the tsunami generated by the strong earthquake that occurred on April 24, 1836, the epicentre of which has been localised near Rossano Calabro, along the Ionian coast of northern Calabria.

“…An important value of TLS instruments lies in the ability to perform repeated surveys in settings that were traditionally difficult to monitor (Young et al 2010). TLS-derived DTMs have been used to provide grain-scale surface roughness data for atmosphere-surface models , to determine the relative ages and the rates and types of surface processes at decimeter scales (Nield et al 2011;van Gaalen et al 2011), and to better improve large-scale models used to classifying coastal flooding and disaster management strategies (Mastronuzzi and Pignatelli 2011;Pignatelli et al 2010). When the topographic data from a TLS survey are accompanied by intensity measurements, individual points can be segregated and/or classified based on spectral characteristics, indicating lithological changes in a scanned feature (Hobbs et al 2010) or the moisture content of ephemeral landforms (Nield et al 2011).…”

Over the last decade, there has been a proliferation of commercially available tripod-mounted Terrestrial Laser Scanner (TLS) systems that use the phase difference or the time-of-flight of emitted pulses of light to rapidly acquire high-density topographic and surface reflectance data. These TLS systems have been well received in the Earth science community because of their ability to collect 10 2 -10 5 measurements per second of azimuth, zenith, distance, intensity, and surface color data at distances ranging from 10 0 to 10 3 m. A TLS instrument's portability, ease of use, and rate of data collection opens the possibility of collecting detailed topographic data at sites where such surveys may not have been possible before. The application of TLS data to current Earth sciences research has allowed us to better understand of the character, timing, rates, and spatial scales of different processes that have been difficult, if not impossible, to evaluate using traditional survey techniques. However, the successes achieved with TLS systems in certain projects may result in unrealistic expectations regarding the density and quality of data that can reasonably be achieved in different settings. This chapter seeks to orient potential or experienced TLS users to its applicability in above-water coastal settings. An emphasis is placed on providing insight into both the variety of current research using TLS data, as well as the compromises in spatial resolution that necessarily arise from field conditions and survey design.

Block and boulder accumulations along the coastline between Fins and Sur (Sultanate of Oman): tsunamigenic remains?

Raised shore platforms are rocky surfaces formed by wave action and subaerial weathering during global high sea level stands. The present height of the raised shore platforms is attributed to several factors, mainly to eustatic sea level changes, isostatic changes in the relative level of land and sea, and vertical tectonic activities. The aim of this study is to investigate the detailed morphology of the raised shore platform along the rocky coastline between Daghmar and Dhabab, in the southeastern part of Muscat Governorate. The study also intends to establish a tentative chronology of the raised shore platforms development. The methodology is based on field observation and documentation, along with satellite and aerial photographs analysis. The results have shown that the study area has a sequence of five successive, well developed raised shore platforms that are well preserved, except the platform at 10m altitude which is only found in isolated fragments. The formation of the raised shore platforms has been affected by a number of constructive factors including tectonic activity, and destructive factors such as fluvial action and subaerial weathering. No absolute dating has been reported or can be obtained from the study area, due to its erosional nature. However, dating from the shorelines adjacent to the study area, ranging in heights from 3 to 15m above sea level, revealed a narrow range of 26,400 to 29,600 years. This period coincides with the last glaciations when the sea level was at about 75m below the present level, and thus did not match with the altitudes of the platforms. This suggests that the platforms could belong to the last interglacial high sea level, when the sea level stood at about 6m above the present level. Based on this scenario, the study concludes that the coastline of the study area has not experienced any significant uplift during the Late Quaternary.
