From: Slow deformation event between large intraslab earthquakes at the Tonga Trench
Illustration of a series of events at the southern part of the Tonga subduction zone after 2009. (1) Beginning of the quiescence of the deeper earthquakes. (2) The 2009 M8.1 shallow earthquake in the far north. (3) Beginning of the trenchward displacements at the upper plate TONG and VAVS stations (red arrows). (4) The 2013 M7.4 intraslab earthquake, and the end of the above “slow deformation event”.
