Oceanic residual depth measurements, the plate cooling model, and global dynamic topography

MJ Hoggard, J Winterbourne… - … Research: Solid Earth, 2017‏ - Wiley Online Library
Convective circulation of the mantle causes deflections of the Earth's surface that vary as a

Thermal–petrological controls on the location of earthquakes within subducting plates

GA Abers, J Nakajima, PE van Keken, S Kita… - Earth and Planetary …, 2013‏ - Elsevier
We find that in young and warm subducting plates, earthquakes occur just below the Moho.
In older plates, earthquakes occur throughout the subducting oceanic crust, as well as the …

Crustal structure of the Yakutat terrane and the evolution of subduction and collision in southern Alaska

LL Worthington, HJA Van Avendonk… - Journal of …, 2012‏ - Wiley Online Library
We present a two‐dimensional velocity model to constrain crustal thickness and composition

Upper plate proxies for flat-slab subduction processes in southern Alaska

ES Finzel, JM Trop, KD Ridgway… - Earth and Planetary …, 2011‏ - Elsevier
The timing of initiation of flat-slab subduction beneath southern Alaska and the upper plate
record of this process are not well understood. We explore the record of flat-slab subduction …
