Modeling groundwater flow induced by coseismic fault zone and near-surface damage
STRUCTURE, MECHANICS, AND HAZARDS OF GEOMETRICALLY COMPLEX FAULT SYSTEMS IV POSTER
tectonophysics | 12 december 2024
Ruei-Jiun Hung, Matthew Weingarten, Shuo Ma, Steve...
Coseismic groundwater level and pore pressure changes are typically modeled with undrainedporoelasticity. However, observed water level changes and un...

Very-near-field coseismic fault-zone pressure drop and delayed postseismic cross-fault flow induced by fault damage from the 2018 M6.3 Hualien, Taiwan earthquake
CHARACTERISTICS OF FAULTS AND FAULT ZONES AND THEIR INFLUENCE ON EARTHQUAKE PHYSICS: OBSERVATIONS, MODELS, AND EXPERIMENTS III POSTER
tectonophysics | 10 december 2024
Ruei-Jiun Hung, Matthew Weingarten, Michael Manga
Groundwater in a fault zone affects the faults architecture, evolution, and state of stress. However, groundwater level observations are rarely made c...

Very‐Near‐Field Coseismic Fault Pressure Drop and Delayed Postseismic Cross‐Fault Flow Induced by Fault Damage From the 2018 M6.3 Hualien, Taiwan Earthquake
JOURNAL OF GEOPHYSICAL RESEARCH: SOLID EARTH
02 october 2024
Ruei-Jiun Hung, Matthew Weingarten, Michael Manga
Earthquakes can produce rock damage, poroelastic deformation, and ground shaking that modify fault zone hydrogeologic properties. Coseismic and pos...
Seismological and hydrological observations of near-fault groundwater response to a surface rupture during the 2018 M6.3 Hualien, Taiwan earthquake
ORIGINS AND IMPLICATIONS OF HETEROGENEITIES IN DRY AND FLUID-PRESSURIZED FAULT ZONES ACROSS SCALES I POSTER
tectonophysics | 15 december 2023
Ruei-Jiun Hung, Matthew Weingarten, Michael Manga
Moderate and large magnitude earthquakes can produce rock damage, soil dilatation, and postseismic creep on various spatial and temporal scales. These...
