Hamiltonian Monte Carlo to Characterize Induced Earthquakes: Application to a M_L 3.4 Event in the Groningen Gas Field and the Role of Prior

The Hamiltonian Monte Carlo algorithm is known to be highly efficient when sampling high-dimensional model spaces due to Hamilton's equations guiding the sampling process. For weakly non-linear problems, linearizing the forward problem enhances this efficiency. This study integrates this linearization with geological prior knowledge for...

Surface-waves suppression using seismic interferometry for imaging and monitoring of the Groningen subsurface

High-resolution seismic reflections are essential for imaging and monitoring applications using data-driven methods such as seismic interferometry (SI) and Marchenko redatuming. For seismic land surveys using sources and receivers at the surface, the surface waves are the dominant noises that mask the reflections. We use SI to suppress surface...

Designing the Adaptive Landscape: Leapfrogging Stacked Vulnerabilities

In the Anthropocene, climate impacts are expected to fundamentally change the way we live in, and plan and design for, our cities and landscapes. Long-term change and uncertainty require a long view, while current planning approaches and policy making are mostly short-term oriented and are therefore not well suited to respond adequately. The...

Insights From Closed-Form Expressions for Injection- and Production-Induced Stresses in Displaced Faults

We consider fluid-induced seismicity and present closed-form expressions for the elastic displacements, strains, and stresses resulting from injection into or production from a reservoir with displaced faults. We apply classic inclusion theory to two-dimensional finite-width and infinite-width reservoir models. First, we simplify the fault model...

A Constitutive Model For Masonry Structures: Practical Application Under Earthquake Loading In Groningen

In this paper, a constitutive model for masonry structures is presented. It is based on the Jointed Rock (JR) model with overall Mohr-Coulomb (MC) failure criterion, and it is implemented as a user-defined soil model in the finite element<br/>code PLAXIS. The Masonry model is a linear elastic-perfectly plastic model capable of simulating the...

Aardbevingen en de woningmarkt in Groningen: Slechte verkoopbaarheid beïnvloedt realisatie verhuiswensen

In deze bijdrage brengen we woningmarktontwikkelingen in het door aardbevingen<br/>getroffen gebied in de provincie Groningen in beeld. De resultaten laten zien dat<br/>het herstel van de woningmarkt in het risicogebied achter blijft bij de rest van de<br/>provincie. De slechte verkoopbaarheid van woningen belemmert huishoudens bij<br/>het...

De Delf

Local inhabitants were of the opinion that a river, or waterway, had existed North of Delweg. There were so-called "groundless" ditches (soft bottomed) and "Uterdieken" (lands outside the dykes). This old waterway therefore would have had no locks but small dykes. Borings and pressure soundings proved this idea to be true. The canal must have...
