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 the cases. https://cariumaes.shop/product-category/footwear/
