Fig. 5From: Shallow tectonic tremor activities in Hyuga-nada, Nankai subduction zone, based on long-term broadband ocean bottom seismic observationsDiagram of the relationship between interplate coupling and shallow tremor activity. When the boundary is creeping, shallow tremors can migrate along strike at a high rate. When the boundary is locked, tremors are less likely to migrate along strike due to the stress shadow effectBack to article page
