Through relative relocation of >6,000 earthquakes from 2010 to 2019 we show that seismic activity within the Nazca slab is concentrated immediately inboard of the most recently accreted terrane (the Panamá–Chocó Block) and that supraslab seismicity is occurring within the subducted continuation of this terrane. The deepest extent of this seismicity occurs only within the Colombian forearc and a gap in the active volcanic arc, indicating that the continuation of this terrane at depth has perturbed the thermal structure of the subduction zone. This perturbation is likely what permits brittle failure to occur above the slab. Within the context of the long-term evolution of the Colombian subduction zone, this seismicity must represent either a transient phenomenon as the continuation of the Panamá–Chocó Block warms and becomes incorporated into the convecting mantle wedge or a site where fluids released by the subducting Nazca slab have been focused, promoting hydrofracture. While additional tests are necessary to distinguish between these possibilities, seismicity within the Nazca slab is most intense directly beneath the locations where supraslab seismicity is concentrated, consistent with hydrofracture due to fluids escaping the slab.

One proposed mechanism to facilitate such behavior is thermal runaway. However, two-dimensional (2D) models that capture highly localized, transient ductile deformation, driven by thermal runaway, remain unexplored. This study presents 2D simple shear models using the pseudo-transient relaxation method optimized for graphics processing units. The models incorporate a Maxwell rheology including compressible elasticity, diffusion creep, dislocation creep, and low-temperature plasticity. Our models capture the nucleation and transient propagation of highly localized ductile ruptures driven by thermal runaway. Depending on rheological parameters, we observe a spectrum of behaviors: (a) broad shear zones which deform only slightly faster than the boundary conditions; (b) localized deformation which is orders of magnitude faster than far field deformation; and (c) highly localized ruptures reaching seismic slip velocities. Runaway intensity scales with nondimensional numbers derived from 1D studies, but its spatial and temporal evolution is more complex, traversing several stages. The rupture front perturbs the local stress field, generating opposing pressure anomalies of up to 1.5 GPa. For mantle transition zone conditions, thermal runaway-driven ductile ruptures can reach seismic slip velocities, confirming it as a viable mechanism for deep-focus earthquakes. Under brittle-ductile transition zone conditions, our models capture thermal runaway driving accelerated creep which disturbs the local pressure field sufficiently to facilitate brittle failure in an otherwise ductile host rock.</p>","PeriodicalId":15864,"journal":{"name":"Journal of Geophysical Research: Solid Earth","volume":"130 6","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2025JB031240","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates Aluto's magmatic and hydrothermal systems using observations of seismicity in the region. We analyze seismic data from January 2012 to January 2014, locating 2,393 events, which lie predominantly along the Wonji Fault Belt (WFB). Event depths reach up to 40 km beneath Aluto, suggesting the presence of a highly crystallized body at shallow depth, consistent with previous magnetotelluric and gravity studies. Deep crustal seismicity likely relates to fluid and/or magmatic processes. High b-values of 1.97 ± 0.10 at Aluto indicates the presence of fluids. Seismicity is negligible beneath Silti Debre Zeyt Fault Zone (SDFZ), previously identified as a highly conductive, indicative of melt. Focal mechanisms show normal faulting in the direction of rift extension and full-moment tensor inversions suggest shear-failure with fluids potentially activating existing faults.

In this study, we deployed dense linear seismic arrays along three slopes of the Changbaishan-Tianchi volcanic area for the first time to obtain unprecedented high-resolution images of the crustal structure by using the teleseismic receiver-function imaging technique. Our results reveal detailed variations of crustal interface characteristics beneath the Tianchi caldera and adjacent areas. Several intracrustal interfaces are clearly revealed that correspond well to geological bodies, which might indicate boundaries of consolidated igneous bodies related to the primitive magmatic activities. A continuous Moho discontinuity at ∼37 km depth is revealed, whereas a weak Moho zone with a vertical offset of ∼4 km appears directly beneath the Tianchi caldera, which shows a clear positive correlation with the average crustal Vp/Vs ratio. We deem that the prominent crustal thickening and the higher Vp/Vs ratio beneath the Tianchi caldera might be closely associated with the complicated mantle-derived mafic materials underplating at the crust-mantle boundary.

The experimental results showed that steady-state shear resistance varied with normal stress and material composition at shear velocities below 1 m/s. A consistent velocity-dependent trend was observed. The steady-state shear resistance of the sample experienced a transition from velocity-strengthening behavior at low shear velocities (below 0.1 m/s) to velocity-weakening behavior at higher shear velocities (above 0.1 m/s). Interestingly, at shear velocities exceeding 1 m/s, the steady-state shear resistance became independent of normal stress and material composition, converging to a similar steady-state value for both crushable and uncrushable materials. Although normal stress and mineral composition had a limited influence on steady-state shear resistance at high shear rates, they significantly affected the weakening rate (the transition from peak strength to steady-state shear resistance), which was strongly correlated with the material's crushing ability, as characterized by the Weibull modulus.

Here, we test this assumption by constructing isostrain and isostress models based on flow laws for single crystals and comparing them to rheological data from aggregates. This analysis reveals that strain rates measured on olivine aggregates agree with those predicted by the isostress model but are an order of magnitude faster than those predicted by the isostrain model. When extrapolated to conditions typical of the shallow upper mantle, the isostress model predicts steady-state viscosities that are one to three orders of magnitude less than those predicted by the isostrain model.

We find that the fault zone structure both amplifies and reduces ground motions not only locally but at distances exceeding 100 km. This impact on ground motions is frequency- and magnitude-dependent, particularly affecting higher frequency ground motions from the foreshock because its corner frequency is closer to the fault zone's fundamental eigenfrequency. Within the fault zone, the shallow transition to a velocity-strengthening frictional regime leads to a depth-dependent peak slip rate increase of up to 70% and confines fault zone-induced supershear transitions mostly to the fault zone's velocity-weakening roots. However, the interplay of fault zone waves, free surface reflections, and rupture directivity can generate localized supershear rupture, even in narrow velocity-strengthening regions, which are typically thought to inhibit supershear rupture.
