van Lent, E.G. (author)The stability of breakwaters in seismically active areas is not always guaranteed. A new approach to model a breakwater subjected to an earthquake is with PM4Sand. The goal of this research is to find if breakwaters subjected to earthquakes can be correctly modelled with PM4Sand.<br/>To investigate PM4Sand a breakwater subjected to an earthquake...master thesis 2020

Brouwer, Romy (author)Since the 60’s the Nederlandse Aardolie Maatschappij (NAM) has been extracting gas from the province of Groningen in the Netherlands. This resulted into seismic activity. However, the buildings in Groningen are not designed to withstand any seismic loading. The assessment of the seismic behavior of the building stock of Groningen is required to...master thesis 2020

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

Chen, J. (author), Verberne, B. A. (author), Niemeijer, A. R. (author)A (micro)physical understanding of the transition from frictional sliding to plastic or viscous flow has long been a challenge for earthquake cycle modeling. We have conducted ring-shear deformation experiments on layers of simulated calcite fault gouge under conditions close to the frictional-to-viscous transition previously established in...journal article 2020

Muntendam-Bos, A.G. (author)The Groningen gas field in the north of the Netherlands is one of the largest gas fields in the world. Since the early 1990s induced seismicity has been recorded. The largest magnitude event observed so far was a Mw = 3.6 event at the town of Huizinge in 2012. The risk posed by the induced events urged the necessity to build comprehensive...journal article 2020

Baharmand, Hossein (author), Comes, M. (author), Lauras, Matthieu (author)In the humanitarian response, multiple decision-makers (DMs) need to collaborate in various problems, such as locating temporary relief distribution centres (RDCs). Several studies have argued that maximising demand coverage, reducing logistics costs and minimising response time are among the critical objectives when locating RDCs after a...journal article 2020

Portugal Quevedo, Hugo (author)In seismically active areas, liquefaction hazards have always been a complicated aspect to evaluate as part of the seismic design of a project. In the case of the design of critical facilities, this becomes crucial, as beyond design basis conditions may elevate the seismic loads significantly and create a considerable liquefaction risk in areas...master thesis 2019

Vummidi, Narayanee (author)The gravity field changes associated with the earthquake are analysed using the GRACE (Gravity Recovery and Climate Experiment) data. GRACE data can track the temporal variations in the gravity field and therefore information on mass redistribution can be achieved. There have been many studies already carried out using the GRACE data to analyse...student report 2019

Chandrashekhar Doddamani, Chaitra (author)Earthquakes in the past few decades has questioned the safety of people and infrastructure in Groningen region and its surroundings areas. The excessive gas extraction from the subsurface has led to human-induced earthquakes in this region. Liquefaction is a phenomenon that occurs as a result of earthquakes, reducing the soil shear strength to...master thesis 2019

Karim, Madina (author)In the past decades, gas productions in the province of Groningen in The Netherlands have caused a significant amount of shallow human-induced earthquakes. Its building stock has shown to be highly vulnerable to these unexpected events. Among various building typologies, damage has been reported for approximately 12.9% of the churches in...master thesis 2019

Kroon, David (author)Liquid storage tanks are used worldwide to contain liquids such as drinking water, fuel and chemicals. Loss of containment during a seismic event can add to an earthquake’s destructiveness by posing a fire hazard, spilling toxic substances or reducing the supply of drinking water. It is therefore important that they remain operational at a pre...master thesis 2019

Alderliesten, Earnest (author)Due to gas extraction, seismic activity has become a major problem in the province of Groningen. Existing buildings are not designed to withstand seismic loads and are likely to be structurally unsafe. Two storey terraced houses with concrete floors and large openings in the ground floor façade walls are onsidered vulnerable, since the in-plane...master thesis 2019

Wellen, Fleur (author), Winkel, Sander (author), Vrinds, Thijs (author), van der Voort, Tjalie (author)In Chile, the Biobío river separates the cities of Concepción and San Pedro de la Paz. Bridges crossing the Biobío river ensure a fast and dependable connection, which contributes to the transport options in the region. With the Biobío region being the second largest contributor to the country's GDP, an unreliable transport network is highly...student report 2019

Manivannan, Padmini (author)Natural or man-made disasters can have a drastic impact on social, economic and environmental aspects of an affected population. Specifically, earthquakes are one of the most potent natural hazards, which cause a disproportionate amount of fatalities, primarily due to a) unexpected building collapses, b) restricted or limited access to basic...master thesis 2019

Linthorst, Joost (author)GustoMSC, an NOV company, is a market leader in the design of offshore wind installation jack-ups. Offshore wind turbine installation has been situated mainly in the North Sea, which is not very seismically active. As a consequence, wind turbine installation jack-ups have been designed and analysed for low seismic excitations. The offshore wind...master thesis 2019

Verlinde, Ronald (author)Offshore wind energy is considered a necessary energy resource, that may stimulate the transition from fossil fuels. Following the successful development in Western Europe, offshore wind is quickly gaining momentum in the Asia-Pacific region. At variance with North-Sea based offshore wind turbines (OWTs), structures installed in the Asia-Pacific...master thesis 2019

Kofou, Stavroula (author)The offshore wind industry has been extended over the last years in areas of active seismicity, such as East Asia, where the design of offshore wind turbines becomes significantly challenging, because albeit aerodynamic and hydrodynamic loads mainly act on the offshore structures, earthquake could emerge as a potentially enormous threat. The...master thesis 2019
