ABSTRACT
Eruption of Merapi Volcano at 2006 aiming to South
Slope passing Gendol River generate the damage impact of Kaliadem
recreation and " almost" touch the Kampong of mbah
Maridjan. Morphological setting in those zones still able to limit the
distribution of Glowing Cloud, so the impact limited. The burying of bunker
kill 2 people caused by bunker location which not yet considered the
possibility of hot cloud slide away from the channel of K. Gendol. Kampong of
mbah Maridjan located in among 2 rivers that is K. Gendol and K. Kuning and
encircled by the hills. This hills existence protects the Kampong of mbah
Maridjan from the 2006 glowing cloud
slide down by magnitude 2 (Volcanic Explosion Index / VEI). Hill trusted by a
local society as protection morphology. Though is safe from the hot cloud, but
if the bigger eruption is happened (VEI > 2), risk of mbah Maridjan Kampong
to the glowing cloud increase and the possibility of hot cloud slide away from
the Cemara hills and run against the Kampong Maridjan become rise. Geographic
Information Systems (GIS) by 3D Analysis tools from Arc View; terrain and Image
overlay tools from Google Earth used in this research to analyze the relation
of Merapi South Slope morphology with the glowing cloud distribution. Transect
or profile tools used to know the effectiveness of valley and hill in limiting
distribution of the glowing cloud. Here GIS can be told to ease the hazard,
vulnerability, and disaster risk of mbah Maridjan Kampong to glowing cloud
analysis.
