| Scope (Session Description) |
During the 2011 Tohoku Earthquake off the Pacific coast, multiple earthquake fault segments along the Japan Trench triggered a massive M9 earthquake. Similar cases, where multiple segments of a subduction zone interact to cause a large earthquake, are known in many subduction zones worldwide. When observing the distribution of volcanic alignments and topography from offshore to onshore regions, in addition to earthquake fault segments in subduction zones, a notable correlation can be identified. This suggests that the responses to plate subduction, ranging across time scales from earthquake cycles to the formation of topography, may be understood in a unified manner as part of the subduction system. Achieving this unified understanding requires interdisciplinary approaches, covering areas such as seismology, volcanology, geomorphology, and geology. This session focuses on the correlation between earthquake fault segments, volcanic alignments, and topography from offshore to onshore regions along subduction zones. We welcome presentations on research that explores the factors responsible for the formation of these correlated segments and the interactions between segments. |
