Ruan, J. (author), Ghose, R. (author), Mulder, W.A. (author)Modelling dynamic rupture is essential to correctly describe the process of induced seismicity. Defmod, an open-source finite-element code featuring quasi-static loading, co-seismic volumetric strain, and dynamic rupture, is used to simulate the entire chain of induced seismicity, from pressure evolution due to fluid injection and extraction,...abstract 2020

Broerse, D.B.T. (author), Visser, P.N.A.M. (author), Bouman, J. (author), Fuchs, M. (author), Vermeersen, L.L.A. (author), Schmidt, M. (author)Large earthquakes do not only heavily deform the crust in the vicinity of the fault, they also change the gravity field of the area affected by the earthquake due to mass redistribution in the upper layers of the Earth. Besides that, for sub-oceanic earthquakes deformation of the ocean floor causes relative sea-level changes and mass...conference paper 2011

Kim, D.S. (author), Kim, M.K. (author), Kim, S.H. (author), Choo, Y.W. (author)The investigation on the seismic behavior of dams becomes crucial but is limited due to lack of experimental or field data. This paper aims to experimentally simulate the seismic behavior of three types of dams; earth-core rock-fill dam (ECRD), concrete-faced rock-fill dam (CFRD), and composite dam which combines concrete dam and CFRD. A series...conference paper 2012

Chen, H.X. (author), Zhang, L.M. (author)Shallow slope failures are one of the most frequent geological hazards in mountainous areas, which pose great danger to people and properties in affected areas. This paper presents a cell-based platform for quantitative risk assessment for shallow slope failures at a regional scale. There are five components in this platform; namely, a digital...conference paper 2015

Rodriguez-Ochoa, R. (author), Nadim, F. (author), Cepeda, J.M. (author)This paper presents an offshore risk analysis in a systematic manner to assess the influence of earthquake-induced submarine slope failure on offshore structures. The risk analysis is carried out for the future development of a natural gas field in deep waters in the south part of the Gulf of Mexico. The study accounts for all the elements in...conference paper 2015

(author)Liquefaction-induced effects are a major threat to shallow foundations built on saturated sand deposits, in seismically active regions. This type of structure is frequently used to support different structures, namely bridges, buildings, gravity walls, etc. Currently, there are few procedures in practice with limited scientific basis for...conference paper 2012

Bertalot, D. (author), Brennan, A.J. (author), Knappett, J.A. (author), Muir Wood, D. (author), Villalobos, F.A. (author)Current procedures relate potential liquefaction induced settlements to foundation size and liquefiable depth. However, the analysis of field case histories suggests that the influence of foundation bearing pressure may also be a significant factor influencing such phenomena. Data from 24 buildings that suffered settlement and tilting as a...conference paper 2012

Licciardello, L. (author), Rots, J.G. (author), Esposito, R. (author)Bed joint reinforced repointing is a strengthening method often used in the Netherlands to counteract settlement damage. This strengthening technique consists of cutting a slot in the mortar joint and installing twisted steel bars embedded in a high-strength repair mortar. Due to the increase in seismic activities, triggered by gas extraction in...conference paper 2021

Mulders, FMM (author)Stress changes related to the depletion of gas reservoirs in the northern Netherlands can lead to small seismic events. Field data analysis makes it very likely that these events are the result of reactivation of existing faults or joints in or near the reservoirs. DIANA is used to model 3D gas reservoirs, in order to analyse stress development...conference paper 2002

Tsouvalas, A. (author), de Oliveira Barbosa, J.M. (author), Lourens, E. (author)Earthquakes induced by the gas extraction is a problem of serious concern in the northern part of The Netherlands. The earthquakes recorded to date can be classified as minor based on their maximum local magnitude (ML=3.6). However, (i) their shallow focus, (ii) the special in-situ soft soil conditions and (iii) the fact the building stock in...conference paper 2017

Jansen, S.J.T. (author)In the Netherlands, the extraction of natural gas from the ground has led to soil subsidence and the occurrence of earthquakes. These earthquakes cause physical damage to buildings and also lead to psychological problems and decreased housing satisfaction. Research on the impact of natural hazards has shown that there is a complicated...conference paper 2018

Morales Beltran, M.G. (author), Turan, Gursoy (author), Yildirim, Umut (author)This article provides an analytical framework to assess the distribution of seismic energy in outrigger structures equipped with viscous dampers. The principle of damped outriggers for seismic control applications lies on the assumption that the total earthquake energy will be absorbed by the dampers, as the rest of the structure remains elastic...conference paper 2017

Gonzalez Acosta, J.L. (author), van den Eijnden, A.P. (author), Hicks, M.A. (author)1D soil column techniques are widely used to evaluate the potential of liquefaction in a system of soil layers. This approach generally leads to large inaccuracies since (1) soil layers are hardly homogeneous and perfectly horizontal and (2) horizontal effects are neglected. To demonstrate the limitation of 1D strategies and the need for 2D...conference paper 2022

Muhammad Iqbal, M.A.F. (author), Kuipers, F.A. (author)A cyber-physical system is often designed as a network in which critical information is transmitted. However, network links may fail, possibly as the result of a disaster. Disasters tend to display spatiotemporal characteristics, and consequently link availabilities may vary in time. Yet, the requested connection availability of traffic must be...conference paper 2016
