    Special sessions on thriving geosciences departments and on cyberinfrastructure in the geosciences highlighted the recent 5th AGU Meeting of Heads and Chairs of Earth and Space Science Departments. The meeting was held in conjunction with the 14th meeting of the Heads and Chairs of Programs in Atmospheric, Oceanic, Hydrologic and Related Sciences, sponsored by the American Meteorological Society (AMS),and the University Corporation for Atmospheric Research (UCAR). “From Surviving to Thriving: Strategies for Advancing University Geoscience Programs in Times of Change” was a topic that drew intense interest. This panel discussion, led by Don Wuebbles (University of Illinois), included panelists Eric Betterton (University of Arizona), Judy Curry (Georgia Institute of Technology), Heather MacDonald (College of William and Mary), and Jim Kirkpatrick (University of Illinois)

    Seismotectonic investigations in the inner Cottian Alps (Italian Western Alps): An integrated approach

    This work integrates the results of recent geological–structural studies with new seismological data for the inner Cottian Alps to investigate the connection between faults and seismicity. The major post-metamorphic tectonic feature of this sector is represented by a N–S structure, named Lis–Trana Deformation Zone (LTZ). Since the Late Oligocene, this structure accommodated right-lateral (Late Oligocene–Early Miocene) and subsequently normal (post-Early Miocene) displacements. In the Pleistocene, the activity of the LTZ seems to have caused the development of lacustrine basins inside the valleys that drain this sector of Western Alps. The present-day seismicity joins the northern part of the LTZ and, southwards, other minor sub-parallel structures. In transversal cross-section hypocentres highlight steep surfaces. Focal mechanisms calculated along this structure show both extensional and strike–slip solutions, mostly with one roughly N–S striking nodal plane. Both sub-horizontal (with NE–SW to ENE–WSW trend) and steeply dipping P axes with N–S to NW–SE sub-horizontal T axes are observed. Even if clear evidence of Quaternary tectonic activity in the area is missing, on the basis of the available seismological and geological data we propose that in the inner Northern Cottian Alps the present-day seismic activity may be connected to the LTZ, interpreted as minor sub-parallel fault strand of the Canavese Line. The kinematics of this structure is consistent with the focal mechanisms calculated in this area. Structural and seismological data indicate that LTZ is active under a bulk dextral–transtensive regime since the late Oligocene in the inner Cottian Alps, in agreement with the data published for the adjacent domain of the chain.Published1-163.3.

    Towards a map of the Upper Pleistocene loess of the Po Plain Loess Basin (Northern Italy)

    Get PDF
    Upper Pleistocene (MIS 4-2) loess sequences occur in most of continental Europe and in Northern Italy along the Po Plain Loess Basin. Loess is distributed along the flanks of the Po Plain and was deposited on glacial deposits, fluvial terraces, uplifted isolated hills, karst plateaus, slopes and basins of secondary valleys. Loess bodies are generally tiny and affected by pedogenesis, being locally slightly reworked by slope processes and bioturbation. Notwithstanding, loess in the Po Plain is an important archive of paleoenviron-mental record and its mapping provides new insights in paleoenvironmental and palaeoseismic reconstructions of Northern Italy
