Title: | The September 26, 1997 Colfiorito, Italy Earthquakes: modeled coseismic surface displacement from SAR interferometry and GPS | Journal: | Geophysical Research Letters | Series/Report no.: | 7/26 (1999) | Publisher: | American Geophysical Union | Issue Date: | 1-Apr-1999 | Keywords: | Colfiorito, SAR, GPS | Subject Classification: | 04. Solid Earth::04.03. Geodesy::04.03.01. Crustal deformations | Abstract: | The largest events of the 1997 Umbria-Marche sesimic sequence were the two September 26 earthquakes of Mw=5.7 (00:33 GMT) and Mw=6.0 (09:40 GMT), which caused severe damage and ground cracks in a wide area around the epicenters. We created an ERS-SAR differenrtial interferogram, where nine fringes are visible in and around the Colfiorito basin, corresponding to 25 cm of coseismic surface dispalacements. GPS data show a maximum horizontal displacement... |
