The Ungaran Volcano (Gunung Ungaran in Indonesian) is a deeply eroded stratovolcano, located south of the northern coastal city of Semarang and west of Ungaran town, at map reference 7.18 degrees South and 110.33 degrees East. It has a height of 2,050 m (6,726 ft). It lies at the northern end of a transverse chain of Java volcanoes extending north-north-west from Mount Merapi. It was formed in three stages, with growth of the youngest edifice taking place during the late Pleistocene and Holocene eras. This youngest edifice was constructed south of three large remnant structural blocks of the second Ungaran volcano. A group of pyroclastic cones was also constructed along the margins of the older edifice. The volcano is deeply eroded and no historical eruptions have been reported, but two active fumarole fields are located on its flanks.
Ungaran has a tropical rainforest climate (Af) with moderate rainfall from June to September and heavy to very heavy rainfall from November to May.
