## Abstract
Gravity and magnetics measurements carried out in Karangsambung – Bayat – Wonosari track, Central Java – Yogyakarta region as much as 34 points for subsurface identification. Modeling and interpretation using both data at 3 sections. Section A lies on Karangsambung area and reach to 1900 m. Section A showed formation of 0.000001 – 0.0014 nT and 2.00 – 2.80 g/cm3 like alluvium, basalt and tuff. Section B lies on Wates – Yogyakarta area and reach to 1700 m. Section B showed formation of (–0.01) – 0.02 nT and 2.40 – 3.00 g/cm3 like andesite intrusive and Merapi volcano sediments. Section C lies on Bayat – Wonosari area and reach to 2000 m. Section C showed formation of 0.00016 – 0.0005 nT and 2.30 – 3.14 g/cm3 like limestone, tuff and diorite intrusive. Based on modeling results from 2D structure inversion method can identify the formation of sediments from volcano activity on Karangsambung – Bayat – Wonosari track, Central Java – Yogyakarta region. The method of this study shows potential application for identify the formation of volcano activity from 2D structure.
