The article titled "Capturing the Epistemic Uncertainty in Subduction Earthquake Rupture Parameters" from ESS Open Archive addresses a fundamental challenge in seismology: quantifying and reducing the uncertainties inherent in modeling how subduction zone earthquakes rupture. Epistemic uncertainty refers to the uncertainties that arise from a lack of knowledge, incomplete data, or limitations in our modeling approaches, distinguishing it from aleatory uncertainty, which represents natural randomness. This type of uncertainty significantly impacts the reliability of seismic hazard and risk assessments, as variations in earthquake rupture parameters can drastically alter predicted ground motions and potential damage. Subduction zones, where one tectonic plate slides beneath another, are responsible for the Earth's most powerful earthquakes, known as megathrust events. The characteristics of these ruptures, such as their size, slip distribution, and propagation, are influenced by factors like the subduction angle, sediment thickness, and frictional properties of the plate interface. Understanding and accurately modeling these rupture parameters is critical for anticipating the severity and impact of future earthquakes and associated tsunamis. Scientific research, often employing tools like logic trees, aims to systematically account for these epistemic uncertainties by considering alternative models and parameters, each assigned a weight based on scientific confidence. By better capturing and reducing these uncertainties, researchers can develop more robust earthquake scenarios, leading to improved disaster preparedness, more reliable building codes, and better-informed risk management strategies, particularly for densely populated regions vulnerable to seismic activity. While the specific findings of this preprint are not detailed without access to the full text, the general scientific endeavor to address epistemic uncertainty in subduction earthquake modeling is a vital and ongoing area of global research. This research has direct relevance for countries like India, which faces seismic threats from nearby subduction zones such as the Indo-Burma and Andaman-Sumatra arcs.
