About Ungaran
Ungaran is a stratovolcano rising to 2,033 meters (6,670 feet) in Indonesia's Sunda-Banda Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Ungaran is located in Indonesia, within the Sunda Volcanic Arc of the broader Sunda-Banda Volcanic Regions. Situated at 7.19° S, 110.35° E in the Southern Hemisphere, the volcano lies within a tropical climate zone. At 2,033 meters above sea level, Ungaran rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
Gunung Ungaran, S of the northern Java coastal city of Semarang, lies at the northern end of four volcanoes extending NNW from Merapi. According to van Bemmelen (1941), the edifice was formed in three stages, with the youngest constructed S of three large remnant structural blocks of the second edifice during the late Pleistocene and Holocene. A group of pyroclastic cones was also constructed along the margins of the older edifice. However, there have been no deposits dated or eruptions reported from this deeply eroded volcano. There have been many geothermal studies, and there are active fumarole fields are located on the flanks. One such study, by Muchni and Suryantini (2025), noted that an uncited geological map indicated a measured age of less than 600,000 years for the youngest dome (Kemalon); other domes were dated at 620 +/- 500 ka (Mergi and Kemalon), and 680 +/- 500 ka (Munding). Kohno et al. (2006, cited in Setyawan et al., 2009), placed the formation of the "Young Ungaran" volcano around 300 ka.

Frequently Asked Questions About Ungaran
Is Ungaran an active volcano?+
Ungaran is not currently classified as active. Its activity evidence is listed as "unknown." No recorded eruptions have been documented. However, no volcano is ever considered permanently extinct.
How high is Ungaran?+
Ungaran has a summit elevation of 2,033 meters (6,670 feet) above sea level. At 2,033 meters, it is comparable in height to many significant mountain peaks and stands well above the tree line.
What type of volcano is Ungaran?+
Ungaran is classified as a Stratovolcano. Stratovolcanoes (also called composite volcanoes) are steep, conical volcanoes built up by many layers of hardened lava, tephra, and volcanic ash. They are among the most common and dangerous types, known for explosive eruptions.
Where is Ungaran located?+
Ungaran is located in Indonesia, in the Sunda-Banda Volcanic Regions. More specifically, it lies within the Sunda Volcanic Arc. Its exact coordinates are -7.188° latitude, 110.346° longitude.
Is it safe to visit Ungaran?+
Ungaran can generally be visited, but as with any volcano, visitors should check local conditions and any advisory notices before traveling. Indonesia may have specific regulations for accessing volcanic areas. Guided tours are often the safest and most informative way to experience a volcano.
