In plate tectonic theory a weak asthenosphere is required to facilitate the motions of the rigid
plates. Partial melt could weaken the mantle, in turn impacting convection, but to date the …

SUMMARY A new amphibious seismic data set from the Cascadia subduction zone is used
to characterize the lithosphere structure from the Juan de Fuca ridge to the Cascades …

We present a new compilation and analysis of broad-band ocean bottom seismometer noise
properties from 15 yr of seismic deployments. We compile a comprehensive data set of …

The forearc topography of the Cascadia subduction zone varies systematically along-strike,
with high-relief in the north and south (the Olympic and Klamath ranges) separated by …

The ocean plates have a simple and short history, making them the most straightforward
realization of the tectonic plate, and the ideal location to study its thickness and definition …

The evolution history of the Sea of Japan back-arc basin remains under debate, involving
the opening of sub-basins such as the Japan and Yamato Basins. Detailed knowledge of the …

The elastic and anelastic structures of the Earth offer fundamental constraints for
understanding its physical and chemical properties. Deciphering small variations in the …

Well-constrained marine sediment characteristics (sediment thickness and shear wave
velocity) are important not only for the study of climate over geologic times scales but also for …

This study presents the velocity structures of the seafloor sediment across the Pacific using
teleseismic body waves recorded by arrays of ocean bottom seismometers (OBSs). We …

The receiver function (RF) is a widely used crustal imaging technique. In principle, it
assumes relatively noise‐free traces that can be used to target receiver‐side structures …
