Summary: Most aftershocks occur in areas with large co-seismic stress changes, but some occur long after the mainshock in remote regions with small stress changes. The triggering mechanism of these remote delayed aftershocks is not well understood. This study investigates the triggering mechanism of delayed aftershocks in the Dead Sea region following the 2023 Mw7.8 and Mw7.6 Kahramanmaras earthquakes.

Summary: The investigation of radiation field in the moon, specifically the vertical magnetic dipoles (VMD), is crucial for moon subsurface detection. This study focuses on analyzing the radiation field produced by VMD located on or near the moon's surface. The researchers derived analytical expressions using an approximate method and considered contributions from low-order and high-order terms. The proposed method and formulas have applications in moon interior exploration.

Summary: Seismic waves during earthquakes induce transient stress changes in the crust, triggering critically stressed asperities at remote distances with significant time delays. The proposed slow-slip modulated delayed triggering model can account for a wide range of observed delay times, including cases of no delay and no triggering. Triggered slow slip events in nature may serve as warning signs of impending earthquakes, highlighting the importance of high-resolution monitoring of active fault zones.

Summary: NASA's InSight has detected a seismic event labeled S1222a, with a moment magnitude of M(W)(Ma)4.7, five times larger than the second largest event. This event is significant as it reveals new geological features and transmits a wide range of frequencies. It is located near the North-South dichotomy and outside the tectonically active Cerberus Fossae region. The event shows no evident geological or tectonic characteristics.

Summary: In this study, we investigate the propagation of water waves in a three-dimensional device composed of alternating open canals and resonant canals with subwavelength resonances. By analyzing the full three-dimensional problem and using Bloch-Floquet analysis combined with an asymptotic technique, we obtain closed forms of the dispersions for resonant canals containing one or two resonators. Our analysis reveals alternating frequency ranges between elliptical and hyperbolic dispersions, with the hyperbolic regime leading to negative effective water depth and negative refraction. Throughout the study, our theoretical results are validated through numerical calculations.

Summary: This study aimed to elucidate the functional importance of DNA-dependent protein kinase catalytic subunit (DNA-PKcs) in sepsis-related multiple organ dysfunction syndrome (MODS). The results showed that deletion of DNA-PKcs improved mitochondrial function and attenuated organ damage in sepsis. Strategies targeting DNA-PKcs expression or activity may be valuable therapeutic options for preventing or reducing mitochondrial dysfunction and organ damage associated with sepsis-induced MODS.

Summary: Observations of time-resolved thermal emission from tidally locked exoplanets can provide insights into their atmospheric temperature structure. This study demonstrates how the temperature field on such planets can be partitioned and understood in terms of different components of atmospheric circulation, and how this partitioning can be used to fit observations of thermal emission.

Summary: Loss of function polymorphisms in phospholipase D3 and D4 are linked to inflammatory diseases, and this study reveals that these proteins function as RNAses and their deletion in mice leads to the accumulation of ssRNA, exacerbating inflammation through TLR signaling pathways. This suggests that both endosomal TLR and cytoplasmic/STING nucleic acid sensing pathways are regulated by PLD3 and PLD4, offering potential implications for treating nucleic acid-driven inflammatory diseases.

Summary: The study experimentally characterizes waves generated by the gravity-driven collapse of a dry granular column into water, identifying three nonlinear wave regimes. This contributes to a better understanding of the rich hydrodynamics of the generated waves, with practical applications for coastal risk assessment.

Summary: This study presents experimental results showing that non-spherical particles in a wave-current flow exhibit higher dispersion, which is influenced by particle shape and volume. The increase in dispersion cannot be solely explained by the increase in transport distance.

Summary: This study identified over 900 slow earthquakes in southwest Japan through data-driven clustering of tremor and low-frequency earthquake catalogs, establishing a more comprehensive database on slow earthquakes in the region. Small slow earthquake clusters exhibit similar scaling properties in terms of energy, duration, and rupture area to larger magnitude fast and slow earthquakes. While small slow earthquake clusters tend to rupture faster in their preferred direction, the average inter-event rupture speeds are comparable to those of larger slow earthquakes, suggesting that rupture speed may not necessarily control the spatial extent or eventual magnitude of slow earthquakes.

Summary: This study presents the largest active submarine eruption ever documented, suggesting that the massive eruption originated from hot asthenosphere at the base of a thick, old, damaged lithosphere. The findings provide insights into how deep magma reservoirs were rapidly drained through dykes and pre-existing faults in the mantle were reactivated.

Summary: The upper continental slope offshore Romania is a complex area with various geological features interacting with each other, impacting slope stability. There are multiple ancient paleo-valleys and Mass Transport Deposits (MTDs) in this region, which may be associated with gravity-driven fault reactivation.

Summary: The study suggests that deploying seafloor seismometers offshore Mayotte can significantly reduce longitude error, but at least 2 cabled seismometers are needed for accurate location and detection of events in the volcano monitoring area. While a one-side land network can perform relatively well within a certain range, beyond a certain distance, seafloor seismometers are still required to improve location and detection performance.

Summary: This study investigates the structure of a new submarine volcano system offshore Mayotte, revealing complex magma reservoirs and conduits down to 40 km depth. The main reservoir located at about 30 km depth is one of the deepest imaged magmatic chambers. Connections between the volcanic edifice and reservoirs or conduits remain unresolved due to limited resolution in the study area.

Summary: The sudden onset of severe seismic activity offshore Mayotte island in the northern Mozambique Channel of the Indian Ocean in May 2018, with around 20 potentially felt earthquakes up to magnitude 5.9, caught the population, authorities, and scientific community off guard. The scientific community had little prior knowledge of the seismic activity in the region due to inadequate seismic network coverage. Over time, a specialized seismology group was established to monitor the ongoing submarine basaltic eruption with improvements in instrumentation and data sets.
