Earthquakes A two-stage earthquake in the AleutiansKevin FurlongThe destructive behavior of great earthquakes in subduction zones, such as in Japan in 2011, depends on details of the earthquake slip. A slip at shallow depth is the dominant driver of tsunami. Using recently developed seafloor geodetic instrumentation, Brooks et al. found that the deeper slip of the July 2021 magnitude 8.2 Chignik, Alaska earthquake was followed 2.5 months later by a second stage of (aseismic) slip.
