Tectonic setting around Japan. Centroid Moment Tensor solution shows the mechanism of the 2024 Hyuga-nada earthquake (b) Pre-seismic SSE (contour interval: 5 cm) 10 July, 2023–6 August, 2024.  Pre-slip with Mw6.0 was detected in the down dip extension of the 2024 Hyuga-nada earthquake, Japan, from late 2023.  (c) Cumulative moment of the rectangular area in (B). The recurrence interval of SSE was shortened to one year from an average of two years right before the earthquake, consistent with simu...
