Where was Merapi formed?
subduction zone
Mount Merapi is located in the subduction zone, where the Indo-Australian Plate is going under the Eurasian Plate. Geologists estimate that the volcano started forming 400,000. It was largely built up by basaltic lava flows, but the lava flows have become more viscous in the last 10,000 years or so.

Is Mount Merapi still active?

Mount Merapi – Geological History. Mount Merapi is the youngest volcano in the series that leads to the south of Mount Ungaran. The mountain is formed due to subduction zones of activity in the Indo-Australian Plate under the Eurasian plate moves cause the appearance of volcanic activity along the central part of the island of Java.
What eruption type is Mount Merapi?
Mount Merapi is a stratovolcano – a tall, conical volcano composed of one layer of hardened lava, tephra (fragmented material produced by a volcanic eruption) and volcanic ash. These volcanoes are characterized by a steep profile and periodic, explosive eruptions. Explosive volcanoes such as Merapi erupt suddenly and with terrifying force.
