Item 1ª Reunión Científica Instituto de Geociencias IGEO (CSIC-UCM) Madrid, 15 y 16 de septiembre de 2011(2011) Pérez-Monserrat, Elena Mercedes; Charco Romero, María; Fort González, RafaelEl objetivo de esta 1ª Reunión Científica del IGEO es presentar la investigación desarrollada y las Unidades Técnicas de las que dispone el IGEO, mostrado su potencial investigador y facilitando la colaboración con otros organismos. En la reunión se presentaron las diferentes sublíneas de investigación que comprende el IGEO, comunicaciones cortas de investigaciones concretas y la actividad realizada por sus Unidades Técnicas de Investigación, a disposición de toda la comunidad científica. El IGEO nace con un importante compromiso para potenciar las investigaciones en Geología, Geodesia y Geofísica. Hay una excelente oportunidad para desarrollar ideas y metodologías que permitan la interacción de las tres disciplinas e incremente el valor del trabajo llevado a cabo, que sea útil para toda la comunidad científica y, sobre todo, para la sociedad. [ABSTRACT] The aim of the 1st Scientific Meeting of IGEO is to introduce the research developed and the Technical Units available in the IGEO, shown their research potential and providing collaboration with other agencies. The meeting presented the different research sublines involving the IGEO, short communications dealt with specific investigations and the activity conducted by its Research Technical Units, available to the entire scientific community. The IGEO born with a commitment to enhance research in Geology, Geodesy and Geophysics. There is an excellent opportunity to develop ideas and methodologies in order to let the interaction of these three disciplines and to increase the value of the research carried out, to be useful for the scientific community and, above all, for society.Item Introduction to Mathematics and Geosciences: Global and Local Perspectives, Volume II.(Pure and applied geophysics, 2016) Charco Romero, María; Orive, Rafael; Díaz Díaz, Jesús Ildefonso; Osete López, María Luisa; Fernandez, JoséItem Space Geodesy, Potential Fields (gravity and geomagnetic) and Geomathematics(1ª Reunión Científica Instituto de Geociencias IGEO (CSIC-UCM), 2011) Fernández Torres, José; Osete López, María Luisa; Herraiz, M.; Arnoso Sampedro, J.; Montero, Javier; McIntosh, G.; Camacho, A.G.; Martin-Hernandez, F.; Charco Romero, María; Ruiz Martínez, Vicente Carlos; Pallero, J. L: G.; Pavón-Carrasco, F. J.; Pérez-Monserrat, Elena Mercedes; Charco Romero, MaríaThis new research sub-line, part of the Research Line/Department at Institute of Geosciences “Earth Dynamics and Earth Observation”, includes the activities of four previously existing research groups: (i) Space Geodesy,Gravimetry and Geomathematics, (ii) Palaeomagnetism, Rock Magnetism and Geomagnetic Modelling, (iii) Terrestrial and Planetary Magnetic Field and Aeronomy, and (iv)Gravimetry, Tides and Geodynamics. These four research groups, which are included on it to work together and cooperate during the next years, have been working until now independently and with very few cooperation between them. In short, it includes the study and modelling of the Earth’s (and others celestial bodies’) shape, gravity and magnetic fields, and their variations in time and space, using terrestrial and space integrated geodetic, gravimetric, geomagnetic and paleomagnetic data and advanced mathematical models and techniques.Item Time-scales of inter-eruptive volcano uplift signals: Three Sisters volcanic center, Oregon (United States)(Frontiers in Earth Science, 2021) Rodríguez Molina, Sara; González, Pablo J.; Charco Romero, María; Negredo Moreno, Ana María; Schmidt, David A.A classical inflation-eruption-deflation cycle of a volcano is useful to conceptualize the timeevolving deformation of volcanic systems. Such a model predicts accelerated uplift during pre-eruptive periods, followed by subsidence during the co-eruptive stage. Some volcanoes show puzzling persistent uplift signals with minor or no other geophysical or geochemical variations, which are difficult to interpret. Such temporal behaviors are usually observed in large calderas (e.g., Yellowstone, Long Valley, Campi Flegrei, Rabaul), but less commonly for stratovolcanoes. Volcano deformation needs to be better understood during inter-eruptive stages, to assess its value as a tool for forecasting eruptions and to understand the processes governing the unrest behavior. Here, we analyze intereruptive uplift signals at Three Sisters, a complex stratovolcano in Oregon (United States), which in recent decades shows persistent inter-eruptive uplift signals without associated eruptive activity. Using a Bayesian inversion method, we re-assessed the source characteristics (magmatic system geometry and location) and its uncertainties. Furthermore, we evaluate the most recent evolution of the surface deformation signals combining both GPS and InSAR data through a new non-subjective linear regularization inversion procedure to estimate the 26 years-long time-series. Our results constrain the onset of the Three Sisters volcano inflation to be between October 1998 and August 1999. In the absence of new magmatic inputs, we estimate a continuous uplift signal, at diminishing but detectable rates, to last for few decades. The observed uplift decay observed at Three Sisters is consistent with a viscoelastic response of the crust, with viscosity of ∼10^(18) Pa s around a magmatic source with a pressure change which increases in finite time to a constant value. Finally, we compare Three Sisters volcano time series with historical uplift at different volcanic systems. Proper modeling of scaled inflation time series indicates a unique and well-defined exponential decay in temporal behavior. Such evidence supports that this common temporal evolution of uplift rates could be a potential indicator of a rather reduced set of physical processes behind inter-eruptive uplift signals.
