We propose a new definition of oblique plate convergence. Our model considers arc-trench
curvature on a spherical Earth, and defines obliquity as the angle between the direction of …

Mesozoic limestone units of the Woyla group were identified in many places across the
northern part of Sumatra, Indonesia. Even though these sedimentary rocks may play an …

Two approaches can be taken to understand geotourism, namely the geological approach
and the geographical approach. This approach will lead to the creation of new geotourism …

Abstract Teluk Segara and Sungai Serut in Bengkulu City are significantly developed
districts. This paper presents a liquefaction vulnerability map for the housing areas. The …

Abstract The Siulak and Dikit segments of the Sumatran fault system, where historical major
earthquakes of Ms 7.6 in 1909, Mw 7.2 in 1995 and Mw 6.6 in 2009 occurred, are distinctive …

Although many earthquake precursors have been proposed to forecast earthquakes, even in
this modern era, short-term earthquake forecasting remains challenging due to the …

At the time of seismic activity, the failure of the foundation structure will lead to building
damage. When the West Pasaman 2022 earthquake occurred, PT. XYZ is constructing a …

One of the criteria that can describe the stress condition under which a fault can rupture is
the Coulomb Failure Criterion. One technique to calculate the Coulomb Failure Stress (∆ …

Determining when and where the next big earthquake will occur is a fundamental challenge
in earthquake forecasting. Although it is reasonable to assume that the next major …

Abstract The 2017 Mw 6.6 Poso and the 2018 Mw 7.5 Palu-Donggala earthquakes are the
most recent large inland earthquakes (Mw≥ 6.5) that occurred in the central part of …
