Title: | About the shallow resistivity structure of Vesuvius volcano | Issue Date: | Feb-2008 | Series/Report no.: | 1/51 (2008) | URI: | http://hdl.handle.net/2122/4986 | Keywords: | Vesuvius volcanic area CSAMT survey resistivity tomography shallow 2D electrical structure |
Subject Classification: | 04. Solid Earth::04.08. Volcanology::04.08.99. General or miscellaneous | Abstract: | Magnetotelluric (MT) soundings performed in the past in the volcanic area of Mt. Vesuvius by two independent research groups showed in the same places MT apparent resistivity curves with very similar shape, but statically shifted by one order of magnitude, at least. To try to resolve this ambiguity new controlled source audio-magnetotelluric (CSAMT) measurements have been carried out in the same MT sites. The interpretation of the CSAMT dataset, combined with that of two shallow dipole-dipole geoelectrical resistivity tomographies previously carried out in the area have allowed a reliable electrical structure to be recovered down to a few km of depth, which will next be used for a best constrained re-interpretation of the deep MT soundings. |
