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.

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

(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

van Zwieten, G.J. (author)A vital component in the management of seismic hazard is the study of past seismic events. Classically, this has been the domain of seismology, which studies the dynamic manifestations of the event to infer properties such as epicenter and moment magnitude. More recently it has become possible to perform similar analyses on the basis of the...doctoral thesis 2023

D’Acquisto, M. (author), Herman, M. W. (author), Riva, R.E.M. (author), Govers, R. (author)Greater landward velocities were recorded after six megathrust earthquakes in subduction zone regions adjacent to the ruptured portion. Previous explanations invoked either increased slip deficit accumulation or plate bending during postseismic relaxation, with different implications for seismic hazard. We investigate whether bending can be...journal article 2023
