Merapi, one of Indonesia's most active volcanoes, lies inone of the world's most densely populated areas anddominates the landscape immediately north of the major cityof Yogyakarta. Merapi is the youngest and southernmost ofa volcanic chain extending NNW to Ungaran volcano.Growth of Old Merapi volcano beginning during thePleistocene ended with major edifice collapse perhapsabout 2000 years ago, leaving a large arcuate scarp cuttingthe eroded older Batulawang volcano. Subsequently growthof the steep-sided Young Merapi edifice, its upper partunvegetated due to frequent eruptive activity, began SW ofthe earlier collapse scarp. Pyroclastic flows and laharsaccompanying growth and collapse of the steep-sided activesummit lava dome have devastated cultivated lands on the volcano's western-to-southern flanksand caused many fatalities during historical time. The volcano is the object of extensive monitoringefforts by the Merapi Volcano Observatory.(Global Volcanism Program)-----------------------------------------------------------------------------------------------------------------------------------MerapiLocation: 7.542° S, 110.442° EElevation: 2.947 mHOME
