These SSEs occur biannually on the same fault patch at a depth of ~30 km on the subducting Philippine Sea Plate slab with average moment magnitudes (<jats:italic>M</jats:italic><jats:sub><jats:italic>w</jats:italic></jats:sub>) of ~6.6. Here we show that the slip accumulation rate (cumulative slip/lapse time) of these SSEs fluctuated over a decadal time scale. The rate increased twice around 2002 and 2013 concurrently with earthquake swarms in the Okinawa Trough. This suggests that episodic activations of the back‐arc spreading at the Okinawa Trough caused extra southward movement of the block south of the trough and accelerated convergence at the Ryukyu Trench.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699994603281280","@type":"Researcher","foaf:name":[{"@value":"Yoko Tu"}],"jpcoar:affiliationName":[{"@value":"Department Natural
