Table 1 Years of strain accumulation at each SSE.

From: Strain accumulation and release associated with the occurrence of SSEs in the subduction zones of the Japanese Islands

SSE (Duration)

Estimated years of strain accumulation (Analysis period prior to the SSE) (years)

Tokai L-SSE (1 July 2000–30 June 2005)

4.69 (3.50)

Boso-Oki S-SSE (9 August 2007–23 August 2007)

1.65 (4.72)

Bungo Channel L-SSE (1) (25 November 2009–6 February 2011)

1.38 (5.30)

Bungo Channel L-SSE (2) (20 April 2018–26 May 2019) (Before correction of coseismic steps)

2.09 (7.20)

Bungo Channel L-SSE (2) (20 April 2018–26 May 2019) (After correction of coseismic steps)

1.33 (5.12)

  1. The values in parentheses in the right column represent the analysis period prior to the SSEs, whereas the values without parentheses in the right column denote the accumulation years calculated by the method described in the section of “Discussion”.
