The microzonation of Sellano – The grade-2 microzonation of Sellano

 

The seismic sequence, which occurred in the Umbria and Marche Regions in 1997- l998, even if it was characterised by quite moderate magnitudes, caused significant damage to buildings and determined the failure of many slopes. This event underlines once more the necessity to zone all the Italian seismic areas in relation to the seismic site amplification, landslide and liquefaction phenomena.

 

The seismic sequence, which occurred in the Umbria and Marche Regions in 1997- l998, even if it was characterised by quite moderate magnitudes, caused significant damage to buildings and determined the failure of many slopes. This event underlines once more the necessity to zone all the Italian seismic areas in relation to the seismic site amplification, landslide and liquefaction phenomena.

The paper presents the seismic site amplification hazard maps and the seismic landslide hazard maps for the town of Sellano (Umbria) and its surrounding villages. The procedures utilised to draw these maps come from studies as regards the seismic site amplification hazard and studies as regards the seismic landslide hazard. Moreover, these procedures follow the guidelines suggested in the Microzonation Seiecmi Geotechnical Hazards [TC4, 1999] and allow a Grade-2 microzonation level to be achieved.
