GEOGRAPHY THROUGH MAPS

Merapi

Merapi stands in central Java near Yogyakarta. Recurrent dome growth and collapse make it a useful example of the connection between viscous lava, unstable slopes and fast-moving pyroclastic flows.

Fast Facts

  • Merapi lies west of Semeru on Java.
  • Lava domes build from relatively viscous magma near the summit.
  • Rain can transform loose eruption debris into lahars after the initial event.
