Land subsidence resulting from groundwater extractions is a global phenomenon adversely affecting many regions worldwide. Understanding the governing processes and mitigating associated hazards require knowing spatial distribution of implicated factors (piezometric levels, lithology, ground deformation), usually only known at discrete locations. Here, we propose methodology based on Kriging with External Drift (KED) approach to interpolate sparse point measurements variables influencing land...
Abstract The Eastern Betic cordillera, southeastern Spain, is characterized by slow tectonic deformation rates and moderate seismicity. Great uncertainties persist regarding the precise kinematics of main fault system within region, Shear Zone (EBSZ). We present a new GNSS (Global Navigation Satellite System) velocity field in Betics, including episodic continuous stations belonging to GeoActiva network, as well all available southern Iberia. use this data build kinematic models with elastic...
We describe a new elastic-kinematic model for the present tectonics of northern Central America and southern Mexico, where Motagua-Polochic fault zone, Middle subduction zone faults in volcanic arc pose significant seismic hazards. The model, which consists angular velocities eight plates blocks, interseismic locking solutions some block-bounding strain-rate tensors three blocks with internal deformation, optimizes fit to regional azimuths earthquake slip directions 200+ station GPS velocity...
It has long been recognized that earthquakes change the stress in upper crust around fault rupture and can influence behaviour of neighbouring faults volcanoes. Rapid estimates these changes provide authorities managing post-disaster situation with valuable data to identify monitor potential threads update seismic volcanic hazard a region. Here we propose methodology evaluate an earthquake on nearby volcanoes create easy-to-understand maps for decision-making support after large earthquakes....
The El Salvador Fault Zone, firstly identifiedafter the 13th February 2001 Mw 6.6 earthquake, is a 150 km long,20 wide right-lateral strike-slip fault system. Ruptures along ESFZ arethought to be responsible for most of historical destructive earthquakesalong Volcanic Arc, as well currentseismicity area. In this work, we focus on geological setting thefault zone by describing its geomorphology and structure, using field-based observations,digital terrain modelling, aerial photograph...
We use continuous and campaign measurements from 215 GPS sites in northern Central America southern Mexico to estimate coseismic afterslip solutions for the 2009 Mw = 7.3 Swan Islands fault strike-slip earthquake 2012 El Salvador 7.4 Guatemala thrust-faulting earthquakes on Middle trench. Our simultaneous, time-dependent inversion of more than 350 000 daily site positions gives first jointly consistent estimates slips all three earthquakes, their combined post-seismic effects secular station...
Abstract Different kinematic models have been proposed for the triple junction between North American, Cocos and Caribbean plates. The two most commonly accepted hypotheses on its driving mechanism are (a) American drag of forearc (b) Ridge subduction push. We present an updated GPS velocity field which is analyzed together with earthquake focal mechanisms regional relief. used to make predictions that tested against available data. An obliquity analysis also presented discuss potential role...
The country of El Salvador, located at the convergent boundary Cocos and Caribbean plates, is subject to frequent seismic events complex surface deformation. This paper presents first Interferometric Synthetic Aperture Radar (InSAR)-based velocity field Salvador produced by combining InSAR new GNSS data, which allows us gain a deeper understanding intricate crustal deformation processes in region. We use L-Band ALOS PALSAR images from five ascending two descending tracks, as well 171...
Abstract We used 33 stations belonging of the Ecuador Continuous Monitoring GNSS Network (REGME) during period 2008-2014, with aim to contribute a methodological approach for estimation new velocity model Continental Ecuador. daily solutions perform analysis time series, obtain models series that best fit, taking into count trend, seasonal variations and type noise. The sum all these components represent real-time thus we can have better parameter its uncertainty. velocities were calculated...

The present study proposes a statistical methodology to rate the habitability of different types buildings after an earthquake. first step was rank variables that affect vulnerability building and formulate with discrimination index makes it possible identify as habitable or non-habitable. This ranking applied criteria established in various international guidelines are used distinguish between (undamaged/no structural damage) non-habitable (structural damage). proposed database information...
Global Navigation Satellite System (GNSS) is an efficient space geodetic method for precise spatial coordinates determination and time series generation. Time analysis very important in order to find tendencies make better predictions. In this study we, analyze of ENU (East, North, Up) determine its performance GNSS network the Ecuador using Hurst coefficient estimation. This composed by 30 stations. was done two approximations. One Rescaled Range (R/S) technic, second Wavelet...
We performed a comparison between the interpolation methods of Kriging and Least Squares Collocation. This allowed to obtain an optimal velocity model earth’s crust for continental Ecuador from field ITRF2008 obtained with GNSS data in period 2008-2014. The best fitting semivariograms two components were Spherical Stable semivariogram. functional Collocation method was third order East component second North component. results compared stations used verification using cross-validation...
The El Salvador Fault Zone (ESFZ) is part of the Central American Volcanic Arc and accommodates oblique separation movement between forearc sliver Chortis block (Caribbean Plate).
