Description
Geographically, Research Areas Located between Coordinates 7ºS to 7ºN and 92ºE to 107ºE. Free Air Anomaly (FAA) and topography data are Used Retrieved from Global Marine Gravity from Geosat and ERS-1 altimetry and Global seafloor Topography from Satellite altimetry and Ship Depth Soundings. It is use amount of 1 '(1 minute) Latitude and Longitude or the sum of 1.85 Km for acquisition as a space. It is use the data released by the BMKG too. The study results showed that the High gravity residual anomaly Associated With high-density rocks. In earthquake occurs on the region flanked by subduction zone boumdary and high gravity residual anomaly. High Residual anomalies associated with high-density rocks. Based on Data and Modeling earn Bouguer Anomaly (ρ = 2.67 gr/cm3), which is Subduction Zone Sumatera Quite Shallow depth. It means that the earthquake in Sumatra Happens Shallow depth. Western part of Sumatra Regional Is Prone Regions Against by Tsunami.
