Estimasi Ancaman Tsunami di Zona Subduksi Sulawesi Bagian Utara Sebagai Upaya Mitigasi Bencana Tsunami

Pendipa, 2021
Pulau Sulawesi sangat rawan akan terjadinya gempabumi. Hal ini disebabkan oleh bertemunya tiga lempeng tektonik, yakni Lempeng Eurasia, Lempeng Filipina, dan Lempeng Indo-Australia.

Modeling Megathrust Zones

Eos, 2018
The past few decades have seen a number of very large earthquakes at subduction zones. Researchers now have an array of advanced technologies that provide insights into the processes of plate movement and crustal deformation. A review article recently published in Reviews of Geophysics pulled together observations from different locations worldwide to ...

Seamount Subduction and Megathrust Seismicity: The Interplay Between Geometry and Friction

Geophysical Research Letters, 2023
AbstractSubducting seamounts are recognized as one of the key features influencing megathrust earthquakes. However, whether they trigger or arrest ruptures remains debated. Here, we use analog models to study the influence of a single seamount on megathrust earthquakes, separating the effect of topography from that of friction.

Hidden Roughness of Subducting Seafloor and Implications for Megathrust Seismogenesis: Example From Northern Manila Trench

Geophysical Research Letters, 2022
A smooth subducting seafloor usually leads to a smooth megathrust, which promotes great earthquakes. We present a case study at the northern Manila Trench to emphasize that the process depends also on sediment accretion and deformation.

Tsunami Evacuation Route Optimization Based on Megathrust Scenario Modeling in Pangandaran, West Java, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology
The southern coastal area of West Java, particularly Pangandaran, faces a high risk of tsunami disasters triggered by megathrust earthquakes. However, current evacuation strategies in the region often lack integration between seismic hazard analysis ...

Global Megathrust Earthquake Hazard—Maximum Magnitude Assessment Using Multi-Variate Machine Learning

Frontiers in Earth Science, 2019
Megathrust subduction faults have caused the largest earthquakes ever recorded in human history. In addition, they are often associated with devastating tsunamis.

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such
