Stochastic Source Modelling and Tsunami Hazard Analysis of the 2012 Mw7.8 Haida Gwaii Earthquake

Katsuichiro Goda et al.

Summary: Stochastic source modelling is a valuable method for assessing future tsunami hazards in the Haida Gwaii region on Canada's Pacific coast. This method accounts for uncertainties in fault geometry and slip heterogeneity, allowing for a wide range of possible tsunami scenarios. By generating multiple stochastic tsunami models, the study provides insights into the variability of tsunami heights and highlights the need for accurate bathymetry and elevation data to improve simulations. The models developed in this study can be used for future probabilistic tsunami hazard analysis and risk management decisions in the region.

Tsunami excitation in the outer wedge of global subduction zones

Qiang Qiu et al.

Summary: This study investigates the structural control on tsunami generation during seismic rupture propagation by analyzing high-resolution bathymetry, seismic reflection profiles, and tsunami-earthquake rupture models at global subduction zones. The researchers find that tsunami run-ups correlate with the width of the outer wedge of the frontal accretionary prism, which is made up of active faults. The prevalence of high-angle faults in the outer wedge provides a more efficient mechanism for seafloor uplift and tsunami wave excitation. This research is important for assessing seismic and tsunami hazards at subduction zones, especially in identified seismic gaps.

Toward an Integrative Geological and Geophysical View of Cascadia Subduction Zone Earthquakes

Maureen A. L. Walton et al.

Summary: The Cascadia Subduction Zone has recorded at least 19 great megathrust earthquakes over the past 10,000 years and is a significant geologic environment for understanding natural hazards. Despite uncertainties, exploring models of earthquake recurrence can help in reducing societal impacts and improving scientific knowledge. Integrating diverse datasets and focusing on geological processes may lead to major progress in addressing outstanding questions about CSZ earthquakes.

Systematic characterization of morphotectonic variability along the Cascadia convergent margin: Implications for shallow megathrust behavior and tsunami hazards

Janet T. Watt et al.

Summary: Recent studies of destructive megathrust earthquakes and tsunamis in Japan, Sumatra, and Chile have revealed a link between forearc morphology and megathrust behavior. This study focuses on the Cascadia subduction zone in northwestern North America, examining tectonic geomorphology, outer wedge taper, and structural vergence to better understand geologic controls on outer wedge strength and segmentation. Results suggest that variability in outer wedge morphology may reflect spatial variations in shallow megathrust behavior occurring over the last few million years. Comparisons to a global compilation also highlight the need for detailed morphotectonic analyses of subduction zones worldwide.
