3.13 Attu section
The Attu section (Figure 6) extends ~400 km from Murray
Canyon to the western terminus of the 1965 Mw 8.7
rupture. It encompasses the hypothesized Buldir and Near blocks of Geist
et al. (1988) and two of the three high-slip asperities in the 1965
event proposed by Beck and Christensen (1991).
We directly incorporate the model of Cross & Freymueller (2008)
depicting 62% coupling extending ~120 km arcward from
the deformation front, corresponding to a lower depth of
~40 km along the subduction interface (Figure 6).
