Malang Plain, Volcanic formation near Malang, Indonesia

The Malang Plain is a group of nine ash cones, maars and volcanic plugs lying around the city of Malang, running from the southeast to the northeast of East Java, Indonesia. Some of the cones may be parasitic cones of the Tengger caldera complex.

Multiple volcanic eruptions during the Holocene period shaped this region and created the distinctive geological formations seen today. These repeated activity events left behind a complex arrangement of different rock formations.

Local farmers use the fertile volcanic soil to grow crops that feed communities across the Malang region. This agricultural practice has shaped daily life and the economy of surrounding villages for generations.

The formations are accessible through guided tours from Malang city, with observation points offering views across the area. Wear sturdy shoes and bring water, as the terrain is uneven and sun exposure can be significant.

Some of the nine cones may be parasitic cones of the Tengger caldera complex, so the plain's landforms may not all be independent volcanoes. The group runs from southeast to northeast around Malang city in East Java.
