The
Ijen volcano complex is a group of
stratovolcanoes in the
Banyuwangi Regency of
East Java,
Indonesia. It is inside a larger
caldera Ijen, which is about 20 kilometers wide. The Gunung Merapi stratovolcano is the highest point of that complex. The name "Gunung Merapi" means "mountain of fire" in the Indonesian language (api being "fire");
Mount Merapi in central
Java and
Marapi in Sumatra have the same etymology.
