| Popis: | Patterns of regional geological structure Sidoarjo has performed detailed interpretation of gravity data is is controlled by the data of surface deformation via GPS. Indication of field data is not obtained a description pattern shallow geological structure being covered by sediment aluviumnya. Gas effuent or subsidence in the Siringbarat and Tanggulangin area is field evidence as controls in the estimation of interpretation of gravity changes and pattern density shallow geological structure. Regional and detailed gravity data interpreted that as an anomaly patterns are trending fault structures with the location of the gas effluent south southwest - north northeast. South trending regional fault structure of the southwest - north north-east to the surface to form a continuous fracture and amblasan as a medium in which the effluent gas is formed. Negative changes in the value of gravity is interpreted as a weak zone or zones shown as mass loss as subsidence located in Siringbarat and Tanggulangin. While positive changes in microgravity, as the removal of the zone located in the southern part of the Sidoarjo Mud pond. |
