Based on analysis of data from a trans‐Mexico temporary broadband seismic network centered Mexico City, we report that the subducting Cocos Plate beneath central is horizontal, and tectonically underplates base crust for distance 250 km trench. It decoupled by very thin low viscosity zone. The plate plunges into mantle near City but truncated at depth 500 km, probably due to an E‐W propagating tear in slab. Unlike shallow slab subduction Peru Chile, there active volcanism along Trans Mexican...

The subduction-related Michoacán–Guanajuato Volcanic Field (MGVF) in central Mexico contains ∼900 cinder cones and numerous larger shield volcanoes of Late Pliocene to Holocene age. We present data for major, trace volatile (H2O, CO2, S, Cl) elements olivine-hosted melt inclusions from eight calc-alkaline with primitive magma characteristics one more evolved alkali basalt tuff ring. samples span a region extending the volcanic front ∼175 km behind front. Relationships between H2O...
New GPS measurements in Chiapas (Mexico), Guatemala and El Salvador are used to constrain the fault kinematics North America (NA), Caribbean (CA) Cocos (CO) plates triple junction area. The regional velocity field is first analysed terms of strain partitioning across major volcano-tectonic structures, using elastic half-space modelling, then inverted through a block model. We show dominant role Motagua Fault with respect Polochic accommodation present-day deformation associated NA CA...
Abstract The subduction of hydrated slab mantle is the most important and yet weakly constrained factor in quantification Earth's deep geologic water cycle. critical unknowns are initial hydration state dehydration behavior subducted oceanic mantle. Here we present a combined thermomechanical, thermodynamic, geochemical model Kamchatka zone that indicates significant beneath Kamchatka. Evidence for comes from across‐arc trends boron concentrations isotopic compositions arc volcanic rocks....
Abstract Geodetically constrained interseismic interplate coupling has been widely used to assess seismic potential in subduction zones. Modeling deformation is challenging, as it involves and often ignores continental internal processes. We present a novel methodology jointly estimate along with upper plate rigid motion surface strain, by GNSS‐derived velocities. use least squares inversion spatially variable Equal Posterior Information Condition Tikhonov regularization, accounting for...
In this study, we investigated the relationships among occurrence regions of megathrust earthquakes and slow earthquakes, estimated interplate temperatures, dehydration processes at plate interface in subduction zone Cocos Mexico, with a focus on Guerrero seismic gap. For purpose, performed series 3-D thermomechanical numerical simulations based combination multiple unknown model parameters. Comparing temperature field for optimal region phenomena, along slab surface where tend to occur is...
Temperature is one of the most important factors that controls extent and location seismogenic coupled transition, partially segments subduction interplate fault. The width fault inferred from continuous GPS observations for steady interseismic period transient last slow aseismic slip event (Mw~ 7.5) occurred in Guerrero zone 2001-2002 extends up to 180-220 km trench. Previous thermal models do not consider this extremely wide interface characterized by shallow subhorizontal plate contact....
Abstract The aseismic slow slip event of 2001–2002 in Guerrero, Mexico, with an equivalent magnitude MW ~ 7.5, is the largest silent earthquake (SQ) among many recently recorded by GPS different subduction zones (i.e. Japan, Alaska, Cascadia, New Zealand). sub-horizontal and shallow plate interface Central Mexico responsible for specific conditions ~100 km long extended transient zone where SQs develop from ~80 to ~190 inland trench. This wide relatively large slips 10 20 cm displacements on...
Abstract Although the thermal regime of interface between two overlapping subducting plates, such as those beneath Kanto, Japan, is thought to play an important role in affecting distribution interplate and intraslab earthquakes, estimation remains challenging date. We constructed a three‐dimensional (3‐D) convection model simulate subduction Pacific plate along Japan Trench Izu‐Bonin Trench, including Philippine Sea Kanto investigated slab water contents this complex tectonic setting.
