The September 2018, $$M_w$$ 7.5 Sulawesi earthquake occurring on the Palu-Koro strike-slip fault system was followed by an unexpected localized tsunami. We show that direct earthquake-induced uplift and subsidence could have sourced observed tsunami within Palu Bay. To this end, we use a physics-based, coupled earthquake–tsunami modeling framework tightly constrained observations. model combines rupture dynamics, seismic wave propagation, propagation inundation. scenario, featuring sustained...

Abstract Taking the full complexity of subduction zones into account is important for realistic modeling and hazard assessment zone seismicity associated tsunamis. Studying requires numerical methods that span a large range spatial temporal scales. We present first coupled framework resolves dynamics over millions years earthquake down to fractions second. Using two‐dimensional geodynamic seismic cycle (SC) model, we model 4 million followed by cycles spontaneous megathrust events. At...

Abstract It has long been recognized that sediments subducting along the megathrust influence occurrence of giant ( M w ≥ 8.5 ) earthquakes. However, limited observation span and concurrent multiple parameters on behavior prevent us from understanding how affect earthquake size frequency. Here, we address these limitations by using two‐dimensional, visco‐elasto‐plastic, seismo‐thermo‐mechanical numerical models to isolate sediment thickness affects subduction geometry seismicity. Our results...

Abstract. Geodynamic modelling provides a powerful tool to investigate processes in the Earth's crust, mantle, and core that are not directly observable. However, numerical models inherently subject assumptions simplifications on which they based. In order use review studies appropriately, one needs be aware of limitations geodynamic as well its advantages. Here, we present comprehensive yet concise overview process applied solid Earth from choice governing equations methods, model setup,...

Abstract Intermediate‐depth earthquakes (focal depths 70–300 km) are enigmatic with respect to their nucleation and rupture mechanism the properties controlling spatial distribution. Several recent studies have shown a link between intermediate‐depth thermal‐petrological path of subducting slabs in relation stability field hydrous minerals. Here we investigate whether structural characteristics incoming plates can be correlated seismicity rate. We quantify 17 by estimating maximum fault...

SUMMARY How does megathrust earthquake rupture govern tsunami behaviour? Recent modelling advances permit evaluation of the influence 3-D dynamics on genesis, propagation, and coastal inundation. Here, we present explore a virtual laboratory in which source arises from coseismic seafloor displacements generated by dynamic model. This is achieved linking open-source computational models that follow discontinuous Galerkin schemes are facilitated highly optimized parallel algorithms software....

Abstract Detailed imaging of accretionary wedges reveals splay fault networks that could pose a significant tsunami hazard. However, the dynamics multiple activation during megathrust earthquakes and consequent effects on generation are not well understood. We use 2‐D dynamic rupture model with complex topo‐bathymetry six curved geometries constrained from realistic tectonic loading modeled by geodynamic seismic cycle consistent initial stress strength conditions. find all faults...

STEM fields in Europe and across the globe are not balanced terms of gender, ethnic racial groups, sexual orientation other aspects diversity (e.g. Fry et al. 2021, Freeman 2018). For example, 2018, women made up over 40% European academic staff, but 2019 only 26.2% full professors were women, less than 25% heads institutes, 31.1% board members (EC She figures 2021). This under-representation has caused institutions to implement new hiring practices, unconscious bias training, intervention...

Venus is often called Earth’s sister planet due to its similar size and mass. Apart from that, however, the two planets are wildly different, with surface temperatures on that easily melt lead a Venusian pressure almost hundred times larger than of Earth. Additionally, completely covered in clouds; obscuring shrouding entire mystery. How did observed topographic features form? Is there still some form tectonics ongoing? Are earthquakes - or indeed:...

The deployment of surface seismometers on the Moon and Mars has demonstrated their ability to recover both internal structure seismicity these planetary bodies.However, planets with dense atmospheres extreme conditions like Venus, deployed at face significant challenges, including short measurement durations due high temperature limitations electronics elevated background noise ground deformations generated by atmospheric dynamics. However, relatively unconstrained Venus is an important...

Warm rocky exoplanets within the habitable zone of Sun-like stars are favoured targets for current and future missions. Theory indicates these planets could be wet at formation remain long enough life to develop. However, it is unclear what extent an early ocean on such worlds influence response potential biosignatures. In this work we test climate-chemistry response, maintenance, detectability biosignatures in warm, water-rich atmospheres with Earth biomass fluxes framework planned LIFE...

The past decade has seen the consolidation of open access practices in scientific publishing, with funding bodies, international agencies and academic institutions requiring free to not only papers but also other output such as datasets computer codes. transition led multiple publishers offer Gold Open Access (GOA) schemes, under which are free-to-read. Compared traditional publication models, GOA comes at a much higher cost for authors. These have had documented negative impact on...

Physics-based dynamic rupture models capture the variability of earthquake slip in space and time can account for structural complexity inherent to subduction zones. Here we link tsunami generation, propagation, coastal inundation with 3D (DR) initialized using a 2D seismo-thermo-mechanical geodynamic (SC) model simulating both dynamics seismic cycles. We analyze total 15 subduction-initialized rupture-tsunami scenarios which source arises from time-dependent co-seismic seafloor...

Abstract Byrne and Krishnamoorthy (2022), https://doi.org/10.1029/2021je007040 estimated the frequency of volcanic eruptions on Venus by scaling eruption obtained from a database containing Earth data. In reproducing their study, I found that number new ongoing in given year is approximately 42, instead previously reported 120 eruptions. This updated estimate (2022) based assumption data can be scaled to an important step toward quantifying volcanism Venus. However, it note this estimate,...

Abstract Subducted sediments are thought to lubricate the subduction interface and promote faster plate speeds. However, global observations not clear‐cut on relationship between amount of motion. Sediments also influence slab dip, but variations in geometry depend multiple factors. Here we use 2D thermomechanical models explore how can dynamics geometry. We find that thick lead slower due an increase megathrust shear stress as accretionary wedge gets wider, a decrease pull buoyant...

Abstract. To a large extent, the thermal structure of subduction zone determines where seismicity occurs through controls on transition from brittle to ductile deformation and depth dehydration reactions. Thermal models zones can help understand distribution by accurately modelling zone. Here, we assess common simplification in zones, i.e. constant values for parameters. We use temperature-dependent parameterisations, constrained lab data, conductivity, heat capacity, density systematically...
