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
earthquakes catalogues seismological compilations pictograms
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...

Ash-fall hazard Colima Volcano Mexico
2015/8/28
The historical eruptive activity at Colima Volcano has been characterized by Strombolian and Merapi type eruptions and Vulcanian explosions associated with dome growth, which have ended in a Plinian e...

be. In particular, the...
Interaction of Cocos and Rivera plates with the upper-mantle transition zone underneath central Mexico
Mantle processes Phase transitions North America
2014/4/10
Receiver functions (RFs) from 224 permanent and temporary stations in central and southern Mexico were used to characterize the upper-mantle transition zone in that region. Discontinuities at 410 and ...
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
2014/4/10
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...
Seismic imaging of the Cocos plate subduction zone system in central Mexico
Mexico inversion mantle wedge oceanic crust subduction zone volcanic arc
2014/4/10
Broadband data from the Meso-America Subduction Experiment (MASE) line in central Mexico were used to image the subducted Cocos plate and the overriding continental lithosphere beneath central Mexico ...

Subduction Mexico receiver function hydrous minerals Bayesian inversion
2014/4/10
Teleseismic converted phases are used to probe the composition of the downgoing oceanic crust as a function of depth along the Cocos slab in central and southern Mexico. Previously, modeling of the re...

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 ...
