Mt. Ungaran
Although there is no specific record of volcanic activity on this mountain, there are hot springs at the foot of the mountain indicating geothermal activity underground. The location of the hot springs is located at Gedong Songo and Gonoharjo Temple, Limbangan, Kendal.

Ungaran volcano material carried by the river intensively form the delta which gradually became the mainland. Currently the fluvial, marine, and anthropogenic processes are intensive to form the morphology of Semarang city.

Mount Ungaran is a quarterly volcano which is the easternmost part of the North Serayu Mountains. The area of Mount Ungaran is to the north bordering the northern part of Java alluvial plains, in the south is a Quaternary mountain route (Sindoro, Sumbing, Telomoyo, Merbabu).

Topology & Geology;
  • The current Ungaran Volkan is a young Ungaran volcano formed from magma activity at the beginning of the holocene, ie after the main cone collapse Old ungaran. Volkan is located in the south of Semarang with distance ± 25 km. based on the shape of this volcan can be grouped into strato volcanic. This is because on the slopes and foot volkan consists of loose materials such as lava breccia and tuff coating. Volkan Ungaran has several peaks, from these peaks there is a stream of tongue-shaped lava flowing down in all directions. On the slopes are still visible former (old remnant Ungaran, which reaches the height between 1300-1600 mdpl). Now volkan this in the rest phase, so that there are post-volcanic symptoms such as hot springs, gas sources sulfur near the Gedong Songo temple complex.
  • Plato Breksi Notopuro is an area around Ungaran complex which is restricted by escarpment (steep slope fracture) in the form of a circle. This circular transverse fault occurs when the old Ungaran volcano cone collapse at the end of the Pleistocene. In the northern part of this fault cut the plateau bridge notopuro with the hill of the temple. Plato breksi notopuro entirely covered by volcanic materials consisting of lava breccia, conglomerate, pebbles, sandstone, and tuff eruption of old Ungaran volcano. Today the surface of the plateau experiencing the erosion process resulting in valleys in the form of the letter “V”.
  • The hills of the temple are including the folds of mountains that lie to the north of the notopuro breccia plateau. These hills cover an area between 4 – 8 km wide, with hills that are not regularly located at an average height of 100 mdpl. The folds on the Temple Hill occur as a result of the downward launch of the old Ungaran volcano cone at the time of the collapse, so that the plain next to it is pressed and folded. Bukit Candi Temple rocks consist of Notopuro layer and Damar Series layers. Semi Damar layer is a layer of Klastika sediment from Ungaran old. The dammar series rocks are grouped into three parts: (1) Lower Damar Series, consisting of a conglomerate mixed with limestone components, sand and clay; (2) The Central Damar series, consisting of breccia mixed with limestone components, sandstone and clay; (3) The upper resin series, comprised of sandstone, tuff, and side by side with a marine sedimentary layer of sandy clay containing sand.
