A computational tool for the development and implementation of a recently published method of 3-D (three dimensional) inversion for gravity data is presented. This method seeks to determine the geometry of an indefinite number of anomalous bodie[...]texto impreso
Montesinos, F. G. ; Camacho, A.G. ; Nunes, Joao C. ; Oliveira, C.S. ; Vieira, Ricardo | Blackwell Publishing Ltd | 2003The seismic response of the Sao Sebastiao volcanic crater, located at the SE end of Terceira Island (Azores), is characterized by an amplification of ground movements inside the crater with respect to the surrounding area. This variability of gr[...]texto impreso
Two experiments of intercomparison between the LaCoste&Romberg Graviton-EG1194 spring gravimeter and the superconducting gravimeters SG-026 and OSG-064, operating respectively at J9-Strasbourg (France) and CDT-Yebes (Spain), were analyzed. The m[...]texto impreso
Furnas Volcano (Sao Miguel Island, Azores) is a steep-sided caldera complex resulting from several collapses. In this paper, we analyse and interpret the gravity survey carried out by the Institute de Astronomia y Geodesia (Spain) and the gravit[...]texto impreso

Gómez-Ortiz, David ; Montesinos, F. G. ; Martín Crespo, Tomás ; Solla, Mercedes ; Arnoso, José ; Velez, Emilio | Elsevier Science | 2014-10Timanfaya National Park is a volcanic area located in the southwest of Lanzarote Island (Canary Islands, Spain). Several lava tubes have been found in the lava flows but many others remain unknown. Its location and identification are important t[...]texto impreso
A gravimetric survey, covering a site 200 m square, was carried out in order to locate karstic cavities. After eliminating the regional trend using a polynomial fit, the residual is modelled by least-squares prediction. Correlated signals for se[...]texto impreso
Nunes, Joao C. ; Camacho, Antonio ; Franca, Zilda ; Montesinos, F. G. ; Alves, Madalena ; Vieira, Ricardo ; Velez, Emilio ; Ortiz, Ester | Elsevier Science | 2006Pico Island is the youngest (texto impreso
This paper presents a gravity inversion method for determining the volumes of bodies with pre-established density contrasts. The method works step-by-step on a prismatic partition of the subsurface volume, expanding the anomalous bodies to fit t[...]texto impreso
Imaging Thermal Anomalies in Hot Dry Rock Geothermal Systems from Near-Surface Geophysical Modelling
Gómez-Ortiz, David ; Blanco-Montenegro, Isabel ; Arnoso, José ; Martín-Crespo, Tomás ; Solla, Mercedes ; Montesinos, F. G. ; Velez, Emilio ; Sánchez, Nieves | MDPI | 2019Convective hydrothermal systems have been extensively studied using electrical and electromagnetic methods given the strong correlation between low conductivity anomalies associated with hydrothermal brines and high temperature areas. However, s[...]texto impreso
Araña, V. ; Camacho, A.G. ; Garcia, A. ; Montesinos, F. G. ; Blanco, I. ; Vieira, Ricardo ; Felpeto, A. | Elsevier Science Publishers | 2000Gravity and magnetic methods have been applied to the Tenerife Island, to provide new information about its internal structure. For this study, 365 gravity stations covering the central part of the island have been selected. The anomalous densit[...]texto impreso
Camacho, A.G. ; Montesinos, F. G. ; Vieira, Ricardo ; Arnoso, José | Blackwell Publishing Ltd | 2001The application of a gravity inversion method enables us to obtain a 3-D density contrast model of the upper crustal anomalies of the volcanic island of Lanzarote (Canary Islands). For this, we use a network of 296 gravity stations distributed o[...]texto impreso
Gorbatikov, AV ; Montesinos, F. G. ; Arnoso, J. ; Stepanova, M. Yu ; Benavent Merchán, María Teresa ; Tsukanov, A. A. | Springer | 2013To study the deep structure of El Hierro Island, Canarian Archipelago, we have used a microseismic sounding method (MSM) based on the fact that heterogeneities of the Earth's crust disturb the spectrum of the low-frequency microseismic field in [...]texto impreso
A new high-resolution (1/12? ×l/12?) regional ocean tide model for Canary Islands region (Spain), by assimilating TOPEX/Poseidon altimetry data and tide gauge measurements into a hydrodynamic model, is presented. This regional ocean tide model i[...]texto impreso
Blanco-Montenegro, I. ; Montesinos, F. G. ; Garcia, Alicia ; Vieira, Ricardo ; Villalain, J.J. | American Geophysical Union | 2005The Bouguer and aeromagnetic anomaly maps of Lanzarote show a gravity high and a dipolar magnetic anomaly over the central part of the island, indicating one isolated source. Assuming that the structure responsible for both anomalies is the same[...]
