| Summary: | Indonesia, a country known as the ring of fire for its long volcano’s curvature. A total
of 127 volcanoes in Indonesia that is well-known, and one of them is Batur Volcano,
which is an active stratovolcano-type volcano, and considered as one of the largest
volcano in the world. Batur Volcano is located in Kintamani District, Bali. By having
a subsurface image of a volcano, a model is then useful for validating other models
that have been previously created using other methods. This research purpose is to
model the subsurface image by using forward modeling method, and to determine the
location of Batur Volcano’s magma chamber using the magnetic method. The
andesite lava value was determined in the model first by using the susceptibility table
with a value of 0.0135 cgs. The anomaly value shows that most of the lava is basaltic
andesite with a value ranged between 0.005 to 0.1 cgs. The magma chamber in the
model is seen at a depth of ± 2900 meters below sea level with an andesite
composition of magma. The depth obtained is in accordance with the geological
model and the susceptibility of the existing data, although the level of accuracy
decreases along with the formed depth model data. |
