| Zusammenfassung |
| The inversion problem concerns the identification of parameters of a
volcanic source causing observable changes in ground deformation data
recorded in volcanic areas. In particular, this paper deals with the
inversion of ground deformation measured by using SAR (Synthetic Aperture
Radar) interferometry and an inversion approach formulated in terms of an
optimization problem is proposed. Based on this inversion scheme, it is
shown that the problem of inverting ground deformation data in terms of a
single source, of Mogi or Okada type, is numerically well conditioned. In
the paper, two case studies of inverting actual SAR data recorded on Mt. Etna
during eruptions occurring in 1998 and 2001 are investigated, showing the
suitability of the proposed technique. |
