    The 2011 Tohoku-Oki (Japan) tsunami inundation and liquefaction investigated through optical, thermal and SAR data (2012)
    IEEE / Institute of Electrical and Electronics Engineers Incorporated
    Details
    Publication Date: 2017-04-04
    Description: We studied the disastrous effects of the tsunami triggered by the Mw 9.0 earthquake that occurred on 11 March 2011 offshore the Honshu island (Japan). The tsunami caused a huge amount of casualties and severe damage along most of the eastern coastline of the island. The dataset used is composed of images from ASTER (visible and thermal) and ENVISAT SAR sensors. The processing and the analysis of data from different sources were performed in order to obtain the tsunami inundation map of the Sendai coastal area, to analyze inland factors driving the tsunami inundation, and to detect the liquefaction effects in the Chiba bay area as well. The obtained inundation line, with a maximum value of about 6 km, has been jointly analyzed with DEM providing the run-up values, which are generally below 21 m in the ca. 60-km-long study area of Sendai. The analysis highlights that the coastal topography influences the inundation process: high-relief zones record the lowest inundation distances, while within the plain the waves entered inland for at least 4 km. We did not observe significant direct effects of the vegetation cover on the inland water penetration along the whole investigated area, nor of the different orientation of the coastline. Moreover, from SAR coherence and intensity correlation a wide area of subsidence is mapped at Chiba bay, which is reasonably related to strong ground shaking and pervasive liquefaction.

    FASA – Fire Airborne Spectral Analysis of natural disasters (2006)
    Details
    Publication Date: 2019-11-04
    Description: At present the authors are developing the system FASA, an airborne combination of a Fourier Transform Spectrometer and an imaging system. The aim is to provide a system that is usable to investigate and monitor emissions from natural disasters such as wild fires and from volcanoes. Besides temperatures and (burned) areas FASA will also provide concentration profiles of the gaseous combustion products. These data are needed to improve the knowledge of the effects of such emissions on the global ecosystem. The paper presents a description of the instrumentation, the data evaluation procedure and shows first results of retrieval calculations based on simulated spectra.

    Reflectance Spectra Measurements of Mt. Etna: A Comparison with Multipsectral/Hyperspectral Satellite (2015)
    An Academic Publisher
    Details
    Publication Date: 2017-04-04
    Description: The reflectance spectra were measured with a FieldSpecPro from 350 nm to 2500 nm during a fieldwork in June 2007. The reflectance has been compared with reflectance obtained by multispectral Advanced Space borne Thermal Emission and Reflection Radiometer (ASTER) and by hyper spectral EO1-Hyperion satellites. Prior the comparison, reflectance spectra have been convolved with ASTER and EO1-Hyperion spectral functions. The results show percentage errors in accordance to those present in literature in the ASTER SWIR range. However, some differences have been confirmed for the ASTER reflectance product (ASTER_07) in visible channels. Regarding EO1-Hyperion, a good agreement of reflectance against field measurement has been found resulting in 5% percentage maximum error in the VIS and up 30% in SWIR spectral range. The capacity of reproducing spectral feature by EO1-Hyperion has been checked on bright pixels (ice-snow) in the acquired image.
    Description: The authors thank D. Pieri, ASTER science Team Member, for the data acquisition planning support and the Jet Propulsion Laboratory, California Institute of Technology for providing ASTER imagery. We further thank the EO1 team for their free data policy, C. Carli for his support in the field measurements. We thank B. Behncke, A. La Spina and F. Murè (INGV Catania) for logistic support and assistance with their knowledge of the Mt. Etna area. A special thanks to Prof. Andrew Hardy for his English check.
