Wavefront distortion across Mt. Vesuvius observed by a seismic array
Local and regional earthquakes recorded at Mt.Vesuvius in 1997 and 1998 by a temporary seismic array have been analyzed with array methods to estimate slowness and backazimuth of correlated phases.The backazimuth observed for the direct P-wave has been compared with the expected direction, and results show surprising large differences in most of th
