Table 4 Years of strain accumulation for each SSE

From: Relationship between strain accumulation and release associated with recent slow slip events on the Japanese Islands

SSE (duration)

Estimated years of dilatation accumulation T (Analysis period prior to the SSE) (year)

Estimated years of maximum shear strain accumulation T (Analysis period prior to the SSE) (year)

The percentage of strain release for dilatation accumulation (%)

The percentage of strain release for maximum shear strain accumulation (%)

Tokai L-SSE (1 January 2013–5 February 2016)

2.3 (7.5)
