SAFETY PROJECT: SENTINEL-1 BASED TOOLS FOR GEOHAZARDS MONITORING AND MANAGEMENT

<p><strong>Abstract.</strong> SAFETY is a two-years European project started the 1st January 2016 and ended the 1st January 2018. The general aim of the project was to develop a methodology and tools in order to exploit Sentinel-1 data for detecting and monitoring the activity state of geohazards (e.g. landslides, volcanic and subsidence) and evaluating their impact on built-up areas and infrastructure networks, at a regional scale. The products of the methodology must support Civil Protection Authorities (CPA) in the risk management activities at a regional scale. In this contest, a strong effort has been spent to generate products that must be operative: reliable and easily to read by users who are not familiar with radar data. The developed procedure is fast, periodically repeatable, and case-adaptable. The methodology, allows the full exploitation of Sentinel-1 constellation data (wide area coverage, high temporal repeatability, freely available data) making feasible long term monitoring plannings. Moreover a free software tool for the Sentinel-1 SAR data processing has been developed. This work presents the developed methodology, through some images of the most significant results obtained over the two test sites of the project (the Canary Island, in Spain, and the Volterra municipality, in Italy), and explains both the strengths and the main lessons learnt for the future steps.</p>

A checklist of the amphibians of Santa Teresa municipality, in southeastern Brazil is presented based on fieldwork, examination of specimens in collections, and a literature review. This new amphibian list of Santa Teresa includes 108 species, of which 106 (~98%) belong to Anura and two (~2%) to Gymnophiona. Hylidae was the most represented family with 47 species (43%). Compared to the previous amphibian lists for Santa Teresa, 14 species were added, 17 previously reported species were removed, and 13 species were re-identified based on recent taxonomic rearrangements. Of the 14 species added, 11 (79%) were first recorded during our fieldwork and specimen examination. It is also the first list of caecilians for Santa Teresa. This list suggests that Santa Teresa has 0.16 species per km2 (i.e., 108 species/683 km2), one of the highest densities of amphibian species in the world at a regional scale. This richness represents 78% of the 136 anurans from Espírito Santo state and 10% of the 1,080 amphibians from Brazil. We highlight the need for long-term monitoring to understand population trends and develop effective conservation plans to safeguard this remarkable amphibian richness.

FACT is the first imaging Cherenkov telescope based on a camera using solid state photosensors (Geigermode Avalanche Photodiodes G-APD aka SiPM). Since October 2011, it has been taking data regularly. Apart from commissioning and calibration measurements, it has already started regular operation, where the main goal is to do long-term monitoring of bright TeV blazars. In June 2012, a flare of Mrk 501 was observed. Thanks to the robustness of the G-APDs, observations can be carried out during strong moon light without aging of the sensors. This improves the duty cycle of the instrument and provides better statistics for long-term light curves. The telescope, situated on the Canary Island of La Palma, is operated, already now, remotely from central Europe. For the future, robotic operation is planned. We report on our experiences during the commissioning, and we present first results from the first 1.5 years of observations.
