Fluid inventory of the North Hikurangi Subduction Zone from integration of physical properties data and thermodynamic models of metamorphic dehydration
AGU 2024
volcanology, geochemistry and petrology | 13 december 2024
Demian M. Saffer, Andrew Smye, Andrew Gase, Peter ...
Fluids exert a first order control on fault strength, slip behavior, and volatile transport in subduction zones. We investigate the fluid inventory of...

Fluid reservoirs of the Hikurangi Plateau and their implications for subduction processes
AGU 2024
volcanology, geochemistry and petrology | 13 december 2024
Andrew Gase, Nathan L. Bangs, Dan Bassett, Christi...
New Zealand's Hikurangi margin is known for recurring shallow slow slip, numerous forearc seeps, and a productive volcanic arc. Fluids derived from th...

Fluid-Induced earthquakes on a 1-meter fault
AGU 2024
seismology | 12 december 2024
David C. Bolton, Luc Lavier, Demian M. Saffer
In the last decade it has been recognized that fluid injection can initiate a spectrum of slip modes, ranging from aseismic creep to elastodynamic rup...

A Predictive Model of the Distribution Coefficient of Boron Desorption: Improving the Use of Boron as a Tracer of Dewatering in Shallow Subduction Complexes
AGU 2024
volcanology, geochemistry and petrology | 12 december 2024
Nicole Ferrie, Demian M. Saffer, Dan Breecker, Bel...
Volatile cycling, earthquake mechanics, and deformation behavior in shallow subduction complexes are modulated by fluid release and migration. Boron (...

Hydromechanical Weakening of the Décollement at the Leading Edge of Accretionary Prisms and the Importance of Mean- and Shear-Stress-Induced Overpressures
AGU 2024
volcanology, geochemistry and petrology | 11 december 2024
Maria A. Nikolinakou, Peter B. Flemings, Demian M....
We quantify stress and pore pressure changes in accreting sediments at subduction zones using large-strain evolutionary geomechanical models and reali...

Discoveries and opportunities in illuminating Geohazards: The role of IODP subseafloor sampling and monitoring
AGU 2024
union sessions | 11 december 2024
Demian M. Saffer
Monitoring and characterization of geohazards represents one core set of challenges that motivate scientific ocean drilling, as articulated in the cur...

Impact of Spontaneous Generation of Splay Faults on the Stress State of Accreting Sediments
AGU 2024
volcanology, geochemistry and petrology | 11 december 2024
Graciela Lopez Campos, Maria A. Nikolinakou, Peter...
We study the impact of the initiation and evolution of upper-plate splay faults on stress and deformation in accretionary prisms. We quantitatively te...

The Role of Carbonate Friction in Subduction Zone Slip Behavior: Insights from Costa Rica and Hikurangi
AGU 2024
tectonophysics | 11 december 2024
Kaitlin Schaible, Peter Miller, Demian M. Saffer
Subduction plate interfaces host a spectrum of slip behavior, from aseismic creep and slow slip events (SSEs), to low-frequency and very-low-frequency...
