Volume 9, Issue 1 , January 2023, , Pages 15-30

https://doi.org/10.22034/gjesm.2023.01.02

Abstract
  BACKGROUND AND OBJECTIVES: Soil or rock types in a region are often interpreted qualitatively by visually comparing various geophysical properties such as seismic wave velocity and vulnerability, as well as gravity data. Better insight and less human-dependent interpretation of soil types can be obtained ...  Read More

Volume 8, Issue 3 , July 2022, , Pages 297-314

https://doi.org/10.22034/gjesm.2022.03.01

Abstract
  BACKGROUND AND OBJECTIVES: Soil or rock properties where buildings are situated play an important role in the ground shaking caused by an earthquake. The highly populated Banda Aceh city in the northernmost Sumatra is flanked by two active faults, the Seulimeum and the Aceh segment. Therefore, it is ...  Read More
