Source signature processing in deep water, Gulf of Mexico: comparison between deterministic deconvolution and phase conjugation
oversampling source signature deconvolution
2015/9/29
The Center for Marine Resources and Environmental Technology has been developing a new method to improve the resolution of high-resolution seismic profiling. To achieve this the source signature is re...
19th century earthquakes in Mexico: three cases, three comparative studies
earthquakes Mexico City
2015/9/14
This paper is a comparative study of the three strongest 19th century earthquakes in Mexico and their effects and impact mainly in Mexico City. The research is based on historical sources and previous...
Historical earthquakes in Mexico. Past efforts andnew multidisciplinary achievements

2015/9/14
The 1985 Mexican earthquakes demonstrated that knowledge concerning their history was still scarce and precarious.In fact those earthquakes acted as triggers, because it was then when a new field of r...
Generation of talc in the mantle wedge and its role in subduction dynamics in central Mexico
Subduction talc serpentine receiver function mantle wedge P-to-S velocity ratio

Geophysical evidence shows the presence of low-seismic velocity material at the surface of slabs in subduction zones. In the central Mexican subduction zone this appears as a thin (～4 km) low-velocity...
Seismic structure in central Mexico: Implications for fragmentation of the subducted Cocos plate
Seismic structure in central Mexico The subducted Cocos plate
2014/4/10
The fine-scale seismic structure of the central Mexico subduction zone is studied using moderate-sized (M4-6) intraslab earthquakes. Regional waveforms from the Mapping the Rivera Subduction Zone (MAR...
Structure of central and southern Mexico from velocity and attenuation tomography
Structure of central and southern Mexico velocity attenuation tomography
2014/4/10
The 3DVp, Vp/Vs, P- and S-wave attenuation structure of the Cocos subduction zone in Mexico is imaged using earthquakes recorded by two temporary seismic arrays and local stations. Direct P wave arriv...
Evidence of a collision between the Yucat′ an Block and Mexico in the Miocene
Seismicity and tectonics Body waves Seismic tomography Subduction zone processes Dynamics of lithosphere and mantle Dynamics: seismotectonics
2014/4/10
We present the evidence for an anomalous southwest-dipping slab in southern Mexico. The main evidence comes from a clear receiver function image along a seismic line across the Isthmus of Tehuantepec ...

Superficial simplicity El Mayor–Cucapah earthquake Baja California in Mexico
2014/4/9
The geometry of faults is usually thought to be more complicated at the surface than at depth and to control the initiation, propagation and arrest of seismic ruptures 1–6. The fault system that runs ...

Geometry seismic properties subduction Cocos plate central Mexico
2014/4/10
The geometry and properties of the interface of the Cocos plate beneath central Mexico are determined from the receiver functions (RFs) utilizing data from the Meso America Subduction Experiment (MASE...
Subducting Slab Ultra-Slow Velocity Layer Coincident with Silent Earthquakes in Southern Mexico
Subducting Slab Ultra-Low Velocity Layer Coincident Silent Earthquakes Southern Mexico
2014/4/10
Great earthquakes have repeatedly occurred on the plate interface in a few shallow-dipping subduction zones where the subducting and overriding plates are strongly locked. Silent earthquakes (or slow ...
Swave velocity structure below central Mexico using high‐resolution surface wave tomography
S Wave velocity structure central Mexico high‐resolutionp surface wave tomography
2014/4/10
Shear wave velocity of the crust below central Mexico is estimated using surface wave dispersion measurements from regional earthquakes recorded on a dense, 500 km long linear seismic network. Vertica...

Seismic attenuation structure central Mexico Image of a focused high-attenuation zone the mantle wedge
2014/4/10
Velocity spectra from moderate-sized earthquakes were used to investigate the P wave attenuation structure in central Mexico. In particular, we included regional events with magnitudes in the range of...
