Summary: The study found shallow triggered creep events along the northern edge of the San Andreas Fault's central creeping section following the 2003 and 2004 earthquakes, with significant changes in creep rate between regional earthquakes. This suggests that triggering connects behavior in the northern San Andreas Fault to the southern section and other regional faults.

Summary: The configuration of the Southern San Andreas Fault at seismogenic depths in the Coachella Valley has been a mystery. By analyzing space geodetic and seismic observations, it has been revealed that the straight southernmost section of the fault is dipping to the northeast, connecting with clusters of seismic activity. This dipping fault geometry has significant implications for fault slip rate, ground shaking intensity, and fault strength.

Summary: Slow, aseismic slip is crucial for understanding large earthquakes and the energy budget of the crust. The North Anatolian Fault experiences aseismic slip at a specific segment since the 1950s, coinciding with a shallow locking depth. Utilizing Sentinel 1 time series and GNSS data, we provide a spatio-temporal description of the fault slip kinematics and propose an alternative model to explain the occurrence of aseismic slip.

Summary: Large, multi-fault earthquakes increase the threat of strong ground shaking and reshape the probability of future events across a system of faults. A study in California revealed that the San Andreas and San Jacinto faults co-ruptured multiple times in the past through the Cajon Pass earthquake gate. These co-rupture events have significant implications for seismic activity in the region.

Summary: Slow, aseismic slip is important in large earthquakes along active faults and controls the amount of strain in the crust for future earthquakes. The factors controlling aseismic versus seismic fault slip include fault zone material properties, pore fluid pressure, and fault plane geometry. This study focuses on the spatial and temporal distribution of aseismic slip along the North Anatolian Fault and provides a description of the kinematics of fault slip using displacement data. The findings show a correlation between aseismic slip at the surface and shallow locking depth, and the occurrence of slow slip events is restricted to a specific section of the fault.

Summary: By studying creep events on the San Andreas Fault, we are able to determine their size and driving forces. We found the presence of many large creep events, suggesting they are not caused by small rainfall disturbances, but more likely driven by complex frictional weakening. Understanding these events is crucial for determining the process of aseismic creep on faults.

Summary: The sudden seismic activity that occurred offshore Mayotte island in May 2018 surprised the local population, authorities, and the scientific community. Due to a lack of seismic network coverage, little was known about the region's seismic activity. To monitor the ongoing submarine basaltic eruption, a seismology group was formed by four French research institutions. They improved instrumentation and data sets, and processed data from Ocean Bottom Seismometers to locate more than 5000 events between February 2019 and May 2020. The earthquakes revealed two separate seismic clusters in the offshore area of Mayotte island.

Summary: The depth variation in earthquake rupture behavior is crucial for quantitative seismic hazard analysis. The study discusses the initial stress setup on a fault based on the Mohr-Coulomb criterion, considering the depth variation. Numerical simulations of the 2019 M-w 4.9 Le Teil (France) earthquake show a shallow ruptured area with ground surface displacement. The rupture extent and seismogenic depth can be controlled by a limited layer at depth, favorably loaded in advance, demonstrating the importance of depth variation in stress loading for assessing the rupture size of moderate crustal earthquakes.

Summary: The 4.9 Mw earthquake in Le Teil, France in November 11, 2019 occurred at a shallow depth, causing the surface rupture of the La Rouviere fault. A secondary surface rupture of the quasi-parallel Bayne Rocherenard fault was revealed through satellite differential interferometry. By using seismic cross-section, the three-dimensional geometry of the local three-fault system was determined. Numerical simulations suggested that the earthquake was triggered by a rapid hydraulic mechanism due to heavy rainfall.

Summary: This article reports a giant active landslide complex located along the western coast of the Aral Sea. The landslide complex, revealed by Sentinel-1 interferometric time-series analysis, has a length of over 150 kilometers and a width of 3 kilometers, with a constant sliding velocity of up to 60 millimeters per year. Systematic subsidence of up to 5 millimeters per year is also observed along narrow strips of terraces. The deformation velocity of the landslide does not correlate with the annual variations of the water level in the southwestern lake of the Aral Sea during the observation period of 2014-2022, suggesting a long-term forcing of the landslide caused by the long-term drop in sea level.

Summary: The proposed BathySent approach for coastal bathymetric mapping using Copernicus Sentinel-2 data was evaluated and compared to ground-truth data in three different pilot sites in Greece. The results showed that BathySent could accurately estimate water depth in the range of 5-14 m with a standard deviation of 2 m compared to sonar-based bathymetry. It was also found that BathySent provided more reliable results compared to conventional Earth Observation-based bathymetry retrieval approaches.

Summary: In November 11, 2019, a M-w 4.9 earthquake occurred near Montelimar, France, with a very shallow focal depth and causing moderate to large damages in several villages. The lack of monitoring stations prompted a swift response from the French scientific community to deploy instruments, conduct field surveys, and study the earthquake's intensity. This comprehensive dataset aims to unravel the earthquake's causes, rupture mechanism, and contribute to seismic hazard assessment in the region.

Summary: The East African rift system is formed above mantle upwellings and the formation of rifts is related to lithospheric thinning and magmatic activity. The amount of splitting varies spatially and the fast axes are predominantly parallel to the orientation of the rifts. Thick lithospheric modules have less splitting and different orientations, which may indicate mantle plume flow. Splitting rotates and increases in strength as it enters the rift zones, suggesting that the anisotropy is mainly present at shallow depths.

Summary: Oxygen fugacity is a fundamental parameter for understanding redox processes in igneous systems. This study compares the Fe-XANES oxybarometry method with the V-in-olivine method for evaluating fO(2) in MORB lavas. The results show that the V-in-olivine method is not applicable to samples with low MgO content, and that the majority of Archean komatiite sources have lower fO(2) than modern MORB.

Summary: The volatile components CO2 and H2O play a major role in mantle melting and heterogeneity. In this study, Ca isotopes were used to trace the lithological heterogeneity in alkaline magmatic rocks. The results revealed the presence of K-richterite and carbonate components as the source of alkaline magmas with low delta 44/40Ca values. These findings highlight the importance of Ca isotopes as a robust tracer of lithological variation caused by volatiles in the Earth's upper mantle.

Summary: Although the current approach to estimate catchment-wide denudation rates using only 10Be concentrations has made significant progress in geomorphology, this study argues for the inclusion of 26Al measurements and testing of steady-state assumptions in slow eroding, formerly glaciated landscapes. The study conducted measurements of both 10Be and 26Al in stream sediments from the Vosges Massif in France and found that elevation, slope, channel steepness, and precipitation were the primary factors controlling denudation rates. The study also revealed a significant relationship between the extent of past glaciation and the cosmogenic (un-)steadiness in the stream sediments.

Summary: Numerical models of Earth's mantle dynamics can predict the vigour and mixing of mantle flow, and the average slab sinking rates are an unexplored parameter that can provide intrinsic information on these characteristics. Through numerical experiments, it has been found that slab sinking rates are strongly correlated with mantle convection and mixing, and may explain geochemical observations from hotspot volcanoes.
