Marine-Origin Natural Hazards: New Frameworks for Assessment, Monitoring, and Risk Reduction

Research on natural hazards has advanced rapidly, helping decision-makers manage land use and reduce disaster impacts. Yet most studies remain land-focused, leaving hazards that originate in the marine environment comparatively underexplored. The ocean undergoes complex transformations that alter established dynamic processes and raise the likelihood of disasters; climate- or tectonically-driven, affecting maritime activities, coastal zones, and island territories. These events carry heavy economic costs, especially for nations dependent on marine sectors, and test their capacity to anticipate, absorb, and respond. A central challenge is developing new ways to understand how the marine environment triggers damaging events, how marine phenomena interact, and how those interactions amplify disasters.This Research Topic seeks innovative methods to uncover the mechanisms of marine natural hazards — including tsunamis, submarine earthquakes, submarine landslides, submarine volcanic eruptions, coastal erosion, subsidence and sea-level rise, storm surges, and hurricanes — and to identify potential trigger zones using marine data-processing technologies and geospatial information. It also aims to advance our understanding of cascading and compound marine hazards, and to develop approaches that improve the accuracy and efficiency of hazard monitoring.We welcome contributions on themes including, but not limited to:• Integrated assessment frameworks for climate- and tectonically-driven marine hazards• Multi-hazard and compound-hazard modelling in marine environments• Linking submarine geomorphological indicators to probabilistic marine-originated hazard modelling• Remote sensing and GIS mapping of marine geohazards• Innovative data-acquisition methodologies in marine geosciences• Novel spatial data models for marine hazard representation• AI-based simulation of marine hazard dynamics• Machine- and deep-learning applications for hazard assessment• Disaster risk reduction and climate adaptation for marine-origin hazards• Mitigation and adaptation pathways for resilient marine systems Topic editors: Kamal Agharroud, Manoj Kumer Ghosh, Chandan Roy Source: https://www.frontiersin.org/research-topics/80909/marine-origin-natural-hazards-new-frameworks-for-assessment-monitoring-and-risk-reduction
