Han, Shin-Chan (author), Sauber, Jeanne (author), Broerse, D.B.T. (author), Pollitz, Fred (author), Okal, Emile (author), Jeon, Taehwan (author), Seo, Ki Weon (author), Stanaway, Richard (author)Earthquakes involve mass redistribution within the solid Earth and the ocean, and as a result, perturb the Earth's gravitational field. For most of the shallow (<60 km) earthquakes with M<sub>w</sub> > 8.0, the GRACE satellite gravity measurements suggest considerable volumetric disturbance of rocks. At a spatial scale of hundreds of km...journal article 2024

Men, Jinkun (author), Chen, Guohua (author), Reniers, G.L.L.M.E. (author)Earthquake-triggered fire domino scenarios (E-FDSs) arise frequently from the interaction between earthquakes and chemical installations, resulting in catastrophic multi-hazard coupling events. The complicated mutually amplified phenomena between natural disasters and chemical accidents significantly aggravates the escalation of domino...journal article 2024

Men, Jinkun (author), Chen, Guohua (author), Reniers, G.L.L.M.E. (author), Wu, Yue (author), Huang, Hailing (author)An earthquake-triggered fire domino scenario (E-FDS) is an example of a typical multi-hazard coupling event. The seismic damage can affect the fire resistance of engineering structures, leading to significant mutually amplified phenomena. In this work, a two-stage experimental program is designed to expound the earthquake-fire coupling...journal article 2024

(author), Gavin, Kenneth (author), Giardina, Giorgia (author)Regional-scale assessment of the damage caused by earthquakes to structures is crucial for post-disaster management. While remote sensing techniques can be of great help for a quick post-event structural assessment of large areas, currently available methods are limited to the detection of severely-damaged buildings. Furthermore, remote...journal article 2024

Macchiarulo, V. (author), Giardina, Giorgia (author), Milillo, Pietro (author), Aktas, Yasemin D. (author), Whitworth, Michael R.Z. (author)Earthquakes have devastating effects on densely urbanised regions, requiring rapid and extensive damage assessment to guide resource allocation and recovery efforts. Traditional damage assessment is time-consuming, resource-intensive, and faces challenges in covering vast affected areas, often limiting timely decision-making. Space-borne...journal article 2024

Diab Montero, H.A. (author), Størksen Stordal, Andreas (author), van Leeuwen, Peter Jan (author), Vossepoel, F.C. (author)Probabilistic forecasts are regarded as the highest achievable goal when predicting earthquakes, but limited information on stress, strength, and governing parameters of the seismogenic sources affects their accuracy. Ensemble data-assimilation methods, such as the Ensemble Kalman Filter (EnKF), estimate these variables by combining physics...working paper 2024

Jain, Uday (author)Masonry structures occupy a significant share of the current building stock due to widespread material availability and cost-effectiveness. Regions with high seismicity, like the Himalayas, have typically developed local seismic culture over the centuries. This has led to improved construction techniques providing an enhanced seismic performance...master thesis 2023

Seismic response of jack-ups: An improved earthquake screening procedure using time history analysisLatooij, Sean (author)Jack-ups are used for offshore wind turbine installation (OWTI). To assess whether a jack-up can safely operate in a desired geographic location with known seismic activity, an earthquake response analysis is required for structural verification. This analysis is generally carried out according to the codes of the International Organization for...master thesis 2023
