The Old Mantle of G .Merapi(See Plate IIIa and IV)., A Few Considerations On The G.Merapi
As already earlier mentioned the G. Herapi exists of two morphologic clearly to be distinguished parts, an older eastern and a younger western part. From the sunnit of the old ringdike, only a small part remains (see portrait 14), of which the eastern part is named G. Pusunglondon (2694.3 a.s.) and the northern G. Paseban (2679= a.s.). The old volcano mantle of the G. Merapi has grown much more denser and higher (+2500= a.s.) than the new eruption cone, as at this the hurled down debris everytine destroyed every begin of vegetation. The old volcano mantle olso shows the typical image of an eroded cone mountain, nanely ravines and ridges, which run up to the sunnit; contrary to the younger eruption cone, which above contourline 2250 has a slippery debris cone.
