Summary:Megathrusts have been the subject of more research recently. Therefore efforts are needed to understand the patterns, novelties, research trends, and potential future research areas connected to megathrusts. This study aims to analyze research trends, document types, source documents, most prolific authors, most cited documents globally, most contributing countries and affiliations, top subject areas and keywords, and visualization mapping of megathrust research trends over ten years. This bibliometric study and review of the literature use metadata from the Scopus database and a mapping application created with the help of the based program of bibliometrics and VOSViewer. The bibliometric results show that the trend of megathrust research over the last ten years is relatively stagnant, with most types of documents being articles and document sources published in journals, one of the journals that contributes the most is the Journal of Geophysical Research: Solid Earth. The top prolific author is Lay, T. The most cited document globally is by Hayes G. P. The top affiliates and countries that researched megathrust the most were Nanyang Technological University and the USA. The top subject areas and keywords in megathrust research in the last ten are Earth and Planetary Sciences and Earthquake. The mapping of visualization of megathrust research trends over the past ten years, seven clusters focus on active faults, crustal earthquakes, geology, geomorphology, amplitude, crustal deformation, seismic, and kinematics. Meanwhile, the opportunity and potential for future researchers to conduct megathrust research are keywords that are still few found, such as mitigation, aftershock, and ground motion.
