The 2021 Mw8.1 Kermadec Megathrust Earthquake: An Event Rupturing the Slab‐Mantle Interface With Up‐Dip High‐Frequency Seismic Energy Radiation

open access: yesGeophysical Research Letters
Megathrust earthquakes often break the slab‐crust interface and radiate high‐frequency seismic waves from the down dip of their coseismic slip. In contrast, we show that the 2021 Mw8.1 Kermadec earthquake deviates from this mode. We resolve the kinematic

Ground‐penetrating radar amplitudes to roots: A numerical modelling framework for mapping coarse root system architecture

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Observations of three‐dimensional (3D) coarse root system architecture remain limited because most measurement approaches require excavation. Here, we combined dense single‐ and multi‐channel 500 MHz ground‐penetrating radar (GPR) surveys with a flow‐guided connectivity framework to non‐destructively characterise the coarse root architecture ...

“Lab‐Quakes”: Quantifying the Complete Energy Budget of High‐Pressure Laboratory Failure

open access: yesAGU Advances
Understanding the interplay of various energy sinks during seismic fault slip is essential for advancing earthquake physics and improving hazard assessment. However, quantifying the energy consumed by major dissipative processes remains a challenge.

A method for mapping apparent stress and energy radiation applied to the 1994 Northridge Earthquake Fault Zone

open access: yesGeophysical Research Letters, 2000
Using the Northridge earthquake as an example, we demonstrate a new technique able to resolve apparent stress within subfaults of a larger fault plane. From the model of Wald et al.

Magnitude dependence of radiated energy spectra: Far‐field expressions of slip pulses in earthquake models [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2003
We examine the radiated waves emitted by events on a model fault. The model deterministically produces a complex sequence of events, with a wide range of sizes, from a uniform frictional instability. The spontaneous rupture events emit a rich spectrum of radiated waves as they nucleate, propagate, and decelerate within the complex stress field left by ...

The Anthropocene and the End of Nuclear Disaster: Normalizing the Fukushima Nuclear Accident

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT This article places the concept of disaster in critical dialogue with that of the Anthropocene, which introduces new imaginaries that negatively affect the governance of crises like nuclear accidents. I argue that tropes surrounding the Anthropocene can depict certain events as apocalyptic calamities while also portraying other events as mere “

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

open access: yesJournal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...
