Depth-varying rupture properties of subduction zone megathrust faults

  author={Thorne Lay and Hiroo Kanamori and Charles J. Ammon and Keith D. Koper and Alexander R. Hutko and Lingling Ye and Han Yue and Teresa M. Rushing},
[1] Subduction zone plate boundary megathrust faults accommodate relative plate motions with spatially varying sliding behavior. The 2004 Sumatra-Andaman (Mw 9.2), 2010 Chile (Mw 8.8), and 2011 Tohoku (Mw 9.0) great earthquakes had similar depth variations in seismic wave radiation across their wide rupture zones – coherent teleseismic short-period radiation preferentially emanated from the deeper portion of the megathrusts whereas the largest fault displacements occurred at shallower depths… CONTINUE READING
