Displacement and Deformation Models for Concepcion Volcano (nicaragua) with Gnss-Gps Techniques: Conceptepe Network

Nicaragua is one of the Central American countries with the highest seismic and volcanic activity in the region due to the continuous interaction of the Coco and Caribe tectonic plates; as well as the local faulting and the different volcanic eruptions produced in the Pacific region. In the Concepción volcano (Ometepe island) there is a GNSS network, the CONCEPTEPE network, made up of continuous stations (CONC, ESPE, JAPO) and episodic stations (ALTA, MOYO, MORR, SINT, OMAJ); being the non-volcanic reference station RIVA (Rivas); and the IGS MANA reference station (Managua). This work presents the geodynamic models of displacement and deformation for the Concepción volcano obtained from GNSS-GPS observations in the context of the regional geodynamic framework. Various data processing methods have been applied and analyzed: PPP and Relative. Different time series analysis techniques have been considered: Wavelets, Kalman, ARMA, ARIMA, CATS, etc. The obtained models are correlated with other volcanological parameters; e.g. seismic activity, landslides. The calculation of the deformation and displacement models has been obtained from the opensource Strain&Stress plugin for QGIS software, designed and developed by the research group of Cadiz University.
