Regional earthquakes followed by delayed ground uplifts at Campi Flegrei Caldera, Italy
Arguments for a causal link
Earthquake-triggered volcanic activity promoted by dynamic and static stresses are considered rare and difficult-to-capture geological processes. Calderas are ideal natural laboratories to investigate earthquake–volcano interactions due to their sensitivity to incoming seismic ...
Hydrothermal, multiphase convection of H2O-NaCl fluids from ambient to magmatic temperatures
A new numerical scheme and benchmarks for code comparison
The dynamic behavior of magmatic hydrothermal systems entails coupled and nonlinear multiphase flow, heat and solute transport, and deformation in highly heterogeneous media. Thus, quantitative analysis of these systems depends mainly on numerical solution of coupled partial d ...
Realistic simulation of structurally complex reservoirs (SCR) is challenging in at least three ways: (1) geological structures must be represented and discretized accurately on vastly different length scales; (2) extreme ranges and discontinuous variations of material properti ...
The dynamics of mid-ocean ridge hydrothermal systems
Splitting plumes and fluctuating vent temperatures
Multiphase thermohaline convection in the earth's crust
II. Benchmarking and application of a finite element - Finite volume solution technique with a NaCl-H2O equation of state
Multiphase thermohaline convection in the earth's crust
I. A new finite element - Finite volume solution technique combined with a new equation of state for NaCl-H2O
We present a new finite element - finite volume (FEFV) method combined with a realistic equation of state for NaCl-H2O to model fluid convection driven by temperature and salinity gradients. This method can deal with the nonlinear variations in fluid properties, sep ...
