Conclusions• Topographic map height values match closely with DEM models
• Vertical RMSE values (Root Mean Square Error) were higher (3x) than the horizontal values especially for the older cones.
• Humid climate: precipitation ranging from 2500 mm/year (east coast) to 500-800mm/year (central) winters are cool and snowy, summers are wet and cloudy
• Climate conditions and vegetation cover determine high rates of erosion and rapid morphological changes, although variability is based on composition of the cones.
• H/W ratios are consistent with published data for several areas of the world with differing climates although the erosional processes in the Kamachatka region are more intensive than published values.
• Peaks of erosion occurred in the first stage 1 to 2 years after eruption as eruptive ashes are stripped from surface, as well as after forest fires
• ASTER DEM data and topographic map data clearly supports the association of younger cones having a higher h/w ratio and slope values while the older cones have a lower h/w ratio and slope values.
