Mahawu Mountain is a stratovolcano volcano located to the east of the volcano Mount Lokon-Gunung Empung in North Sulawesi, Indonesia. While in the distance, Manado Tua Island and surrounding islands seemed to float on the vast Sulawesi sea.
The Minahasa people named Mahawu on this mountain because they often emit ash. In addition to calling it mahawu, this mountain is also called Mount Roemengas.
Even though it was already inactive, the smell of sulfur carried by the wind still clearly smelled. This mountain crater lake is now small because some of the edges have dried up …

History of eruption;
Mahawu Mountain according to the Indonesian Volcano Base Data, before 1789 there were 3 eruptions from the central crater. There is no further information regarding this activity, both the year and the description of its activities.
Whereas the eruption in 1958, according to M. Pantouw’s report, vibrations were recorded by seismographs at Kakaskasen Post for 78 minutes, but which only felt instantaneously and occurred suddenly, because previously no recorded vibrations or vibrations were felt…

Type of eruption;
From the eruption products, the history of activities, shapes and structures that can be identified showed that in the past the volcanic activity of Mount Mahawu was quite large. The presence of the caldera and other structures indicates large magmatic activity which is then followed by the activity of the fault structure. Besides that, it was found that there was an indication of a side eruption that produced lava. The history of activities recorded in historical time is mostly in the form of phreatic and phreatic magmatic eruptions, while those that are purely magmatic are relatively not occurring…
Topology & Geology;
Based on Bouger’s anomaly map and geological reports, 7 modeling cross sections were made to see the crater structure.
Of all the models there is a body that is negative (low density) that extends. In the cross section through the crater (5 pieces), under the kawa there is a negative body that is located deeper.
Five of the 7 2-dimensional models are arranged in 3-dimensional images (not 3-dimensional models) in order to provide stereometric images, and to control the cross-section of one another.
From the results of the examination and looking at the model, it can be concluded that the Mahawu Mountain area is mainly an area made of cross section models filled with bodies of low density, this supports geological reports that activities move around, so many former craters are no longer active…
