Horizontal deformation patterns of an instable lava terrace at Sciara del Fuoco, Stromboli volcano (2003-2005) by using aerial image cross-correlation

摘要: Throughout the 2002-2003 Stromboli eruption, lava flows emitted form vents at about 640 m a.s.l. covered large part of tsunamigenic landslide formed on 30 December 2002, just onset eruption. The resulting compound field a thick terrace in upper part, close to vents, roughly corresponding with head 2002 landslide. monitoring movements and this unstable lave was conducted by using multitemporal comparison photogrammetric Digital Elevation Models geodetic network (THEODOROS system). These systems depicted continuous deforming process characterized strong downslope motion accompanied an important vertical component terrace.
