Rocks stretch, break, and flow, depending on how and under which conditions they are loaded. A new formulation to better capture Earth’s rheology is explored in the context of plate thickness.
Regional strain rate may play as significant a role as temperature in governing the depth distribution of earthquakes in mantle lithosphere.
A peak in seismic P-wave – S-wave velocity ratios at the lithosphere-asthenosphere boundary beneath old Pacific lithosphere requires an additional property besides temperature as an explanation.
A new model, ArcCRUST, reveals with unprecedent resolution the geometry and the thermal state of the oceanic crust of the High Arctic and Circum-Arctic domain.
What happens when subduction stops? A team of scientists installed a dense seismic network in Borneo to investigate causes and consequences of subduction termination.
A new high-fidelity tomography harnesses USArray data to expose a wealth of noteworthy crustal and upper mantle structures, including previously unknown anomalies beneath the Appalachians.
Ambient Noise Tomography Workshop (MIMOSA); Tucson, Arizona, 17–23 January 2016
Research shows that a broken lithosphere underneath the island of Hawai'i could explain the island's patterns of seismic activity.
Underneath old and stable pieces of Earth's crust in North America, the mantle's uppermost portion contains multiple layers that change the velocities of seismic waves.
Scientists look at deep earthquake signals to map how seismic waves lose energy in the upper mantle across the United States.
