Balestrini, F.I. (author)Seismic methods are widely used for the exploration of the Earth’s subsurface. While they allow higher resolution compared to other geophysical methods, their performance depends on site and geological characteristics, and the volume and type of recorded information. Additionally, data processing plays a critical role in the efficacy of the...doctoral thesis 2023

Manos, Peter (author)For the first time since the 1970s, concrete plans are in motion to bring humans back to the Moon through the Artemis programme. The dawning era of space exploration aims to set the groundwork for long-term off-Earth settlement, with sights on bringing the first humans to Mars. In order to provide a safe means of inhabiting extraterrestrial (ET)...master thesis 2023

Jain, Uday (author)A large share of the buildings today is still masonry buildings, both reinforced and unreinforced. Post-earthquake reconnaissance studies have shown a remarkable difference between the performance of reinforced and unreinforced masonry buildings. While the unreinforced masonry buildings tend to suffer severe damage, even collapse, resulting in...student report 2023

Oumejjoud, Salima (author)Using a field classification, I have assessed the likelihood that a gas field caused a seismic event. I have put the focus on all of the minor gas fields located in the Rotliegend sandstone formation in the Netherlands. These gas fields were divided into five geologically distinctly different regions: the North Holland Platform (NHP), the...master thesis 2023

Janssen, M.T.G. (author), Draganov, D.S. (author), Barnhoorn, A. (author), Wolf, K.H.A.A. (author)As part of a seismic monitoring project in a geothermal field, where the feasibility of re-injection and storage of produced CO<sub>2</sub> is being investigated, a P- and S-wave seismic velocity characterisation study was carried out. The effect of axial and radial (up to 42 MPa) stress, pore pressure (up to 17 MPa), pore fluid (100% brine...journal article 2023

Sensitivity of the seismic response of monopile-supported offshore wind turbines to soil variabilityPanagoulias, S. (author), de Winter, C.M.A. (author), Navalkar, S.T. (author), Nernheim, A. (author)The expansion of the offshore wind industry in areas with high seismicity has led to engineering challenges related to the design of the offshore wind turbines (OWTs). Monopiles, i.e., tubular steel piles of large outer diameter, low aspect ratio (penetration depth over outer diameter), and relatively thin pile wall, are traditionally the...journal article 2023

D’Amore, Simone (author), Bianchi, S. (author), Ciurlanti, Jonathan (author), Pampanin, Stefano (author)In the last decades, recent earthquakes have further highlighted the high vulnerability of non-structural components. Post-earthquake damage due to building envelope, equipment and building contents can lead to substantial economic losses in terms of repair costs and daily activity interruption (downtime). Moreover, non-structural damage can...journal article 2023

Rojas, D. (author), Quintana Gallo, P. (author), Pürgstaller, A. (author), Bianchi, S. (author), Ciurlanti, J. (author), Pampanin, S. (author), Bergmeister, K. (author)This article presents a numerical study on the influence of the anchorage shear hysteresis on the seismic response of nonstructural components (NSC) connected to multi-storey reinforced concrete (RC) buildings, and of the anchorage itself. To cover a variety of different types of shear hysteresis shapes, this contribution considered the...journal article 2023

Ciurlanti, J. (author), Bianchi, S. (author), Pampanin, Stefano (author)The severe socio-economic impact of recent earthquakes has represented a tough reality check, further confirming the mismatch between society expectations and reality of seismic performance of modern buildings. Life-safety code-compliant design criteria are not enough when dealing with new structures. To raise the bar in terms of structural...journal article 2023

Nuñez Enriquez, Daniel (author)Seismic events have shown the hazardous and expensive consequences resulting from seismic damage of non-structural elements. For this reason, the concern regarding the seismic performance of glazed curtain walls has acquired more relevance in the building industry; however, there is still a gap of information in the literature about this topic....master thesis 2022

Bouwmeester, Boudewijn (author)The increasing global demand of renewable and clean energy has led to the exponential growth, development, and interest in the offshore wind energy industry and expansion towards earthquake-prone areas. Offshore wind turbine structures, typically supported by a tubular monopile foundation, are increasing in size to meet the increasing human...master thesis 2022

Chamarczuk, Michał (author), Draganov, D.S. (author), Quiros, Diego (author), Malinowski, Michał (author)Most of the ambient-noise studies are performed with sensor arrays located at the surface. Passive recordings containing seismic arrivals from subsurface sources could be seen as having a geometry resembling reverse vertical seismic profiling (RVSP). In such scenarios, the intersource seismic-interferometry technique can be used to redatum...journal article 2022

Zhang, D. (author)For exploration and development of the earth, seismic surveys are acquired to provide information about the subsurface, within specifications of accuracy set by geologists and engineers, and within business constraints on budgets and turn-around time for processing and interpretation of the data. The case of seismic surveys that are acquired,...doctoral thesis 2022

Delavinia, Dimitra (author)New offshore wind farms consisting of monopile-founded Offshore Wind Turbines (OWTs) are to be built in earthquake-prone areas. To design the monopile foundation and to accurately define the dynamic response of an OWT, the soil-monopile-superstructure interaction should be modelled properly. Due to the fact that the Three-Dimensional (3D) Finite...master thesis 2022

Aalbers, Jesper (author)This study presents the structural response of a Submerged Floating Tunnel (SFT) subjected to earthquake loading and other relevant static loading types. The SFT is a competitive solution for crossings of deep seas, canals and fjords, as it is submerged in water and floats at a fixed submersion depth. It is supported by its buoyancy and tethers,...master thesis 2022

Vinard, N. (author)When humans started started exploiting the abundant underground natural resources the Earth has to offer such as hydrocarbons, minerals and heat, we started to experience earthquakes that are related to this exploitation, so called induced earthquakes. Under certain conditions those can damage local infrastructure. However, most events are weak...doctoral thesis 2022

Schaly, Jan (author)With a rapid increase in computational resources two dimensional full-waveform inversion is evolving into a promising tool for near-surface geophysics. However, near-surface applications suffer from local minima due to amplitude errors associated with two dimensional full-waveform inversion. By clever definition of the misfit function, the...master thesis 2022

Hirsch, Quentin (author)In 3D seismic data acquisition, sufficiently dense spatial sampling is most often not possible, because of physical, financial, and temporal constraints. The resulting aliased data is a major obstacle for accurate subsurface images. Therefore, methods are needed to reconstruct these sparse data to an adequate sampling. We develop a novel...master thesis 2022

Hassing, Sverre (author)CO2 and H2S are reinjected at Hellisheiði, Iceland, to reduce the emissions of greenhouse gases. An active-source seismic campaign was done in July, 2021, to image the reinjection reservoir with various seismic methods for consecutive monitoring. At the same time, passive-source seismic data was recorded for imaging.<br/>We process this passive...master thesis 2022

Tuppen, Sam (author)Motivated by environmental concern, the industry has been developing an alternative marine seismic source, in particular a marine vibrator. By spreading the emitted energy out over time, vibrator sources are perceived to be less intrusive to marine mammals. It is also believed that vibrators have greater control of the emitted source wavelet...master thesis 2022
