However, the effects of length scale of heterogeneity on macroscopic fault sliding behavior remain underexplored. We investigate this question for subduction megathrusts, via linear stability analysis and quasi-dynamic simulations of slip on a dipping fault characterized by rate-and-state friction. Frictional heterogeneity is imposed through alternating velocity-strengthening and velocity-weakening (VW) patches, over length scales spanning from those representative of basement relief (several km) to the entrainment of contrasting lithologies (100s of m). The resulting fault behavior is controlled by: (a) the average frictional properties of the fault, and (b) the size of VW blocks relative to a critical length scale. Reasonable ranges of these properties yield sliding behaviors spanning from stable sliding, to slow and seismic slip events that are confined within VW blocks or propagate along the entire fault.</p>","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"52 8","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2025GL115738","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143871767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we focus on how mantle wedge serpentinite may affect megathrust seismogenesis at Japan Trench—an end-member cold subduction zone. Based on thermal modeling constrained by heat flow observations and serpentine frictional behavior reported in the literature, we hypothesize the presence of a lizardite-rich soft barrier starting at the mantle wedge corner (MWC) and an antigorite-rich seismic zone farther downdip. This soft-barrier hypothesis can explain why two groups of megathrust events are roughly divided by the MWC yet the giant 2011 Tohoku-oki earthquake ruptured through the MWC. Seismogenic antigorite patches embedded in semi-viscous to viscous fault zone materials can explain other observed seismic phenomena of the deeper part of the megathrust such as aftershocks, persistent repeating earthquakes, and strong radiation of short-period energy in great earthquakes.</p>","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"52 8","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2025GL115446","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationship between the Loop Current (LC) and freshwater distribution are further investigated using a stepwise linear regression model. The relative impacts of river discharge and surface advective freshwater fluxes are quantified, and it is concluded that basin-wide SSS depends significantly on the discharge from the Atchafalaya River, which leads by 4 months.

To understand this volcanic history, we developed a 2-D numerical model of magmatism and mantle convection; the effects of the PKT on lunar evolution are considered by initially imposing a region of localized radioactive enrichment. The calculated volcanism is driven by two different mechanisms. Early volcanism occurs when magma generated in the deep mantle by internal heating ascends to the surface as partially molten plumes. The basaltic blobs in the uppermost mantle formed by this magmatism then sink into the deep mantle, triggering further plumes that cause a resurgence of volcanism in its later history.

Our results reveal that exceptional warming in the tropical-subtropical North Atlantic (TSNA), characterized by a warm blob off North Africa reaching 1.2 K, played a crucial role. The TSNA warming induced a low-pressure anomaly over the mid-latitude North Atlantic and Europe, facilitating moisture transport and convergence toward Eastern Europe, leading to heavy rainfall. While the concurrent El Niño event and positive Indian Ocean Dipole may contribute to this process, their impacts were relatively modest compared to TSNA warming.

We find that wave energy strongly (linearly) increases alkalinity formation from olivine when energy input is beyond a certain threshold. However, when olivine is mixed with organic-poor sand, energy input also increases the loss of alkalinity possibly by promoting precipitation reactions thereby canceling out the benefits of waves on alkalinity formation.
