“…Melt inclusion studies estimate water contents from both volcanoes at ∼3% (Benjamin et al., 2007; Di Piazza et al., 2019), which could equate to a shared reservoir at depth. This is supported by GPS (Battaglia et al., 2019) and gravity (Lücke et al., 2010), both models indicating that a shared body beneath both Irazú and Turrialba as the cause. Figure 9h compares the gravimetric data (Lücke et al., 2010) against our local‐scale tomography, confirming what appears to be a general agreement between the low V S values (ILV, Figure 10b and Figure S6b in Supporting Information S1), and the regions characterized by densities of 2.6 kg m −3 (Lücke et al., 2010).…”

“…This shallow deflection, or flexure, at 2 km depth may be caused by a small shallow magmatic reservoir. Geodetic data, measuring ground deformation of the ITVC (Battaglia et al., 2019) suggests a more complex plumbing system is required, for example, a superficial reservoir, to satisfy the significant residual velocities at Turrialba, supporting the existence of the SLV‐T. Seismicity attributed to SO 2 degassing (Conde et al., 2014) contribute to the schematic magmatic system devised by DeVitre et al.…”

Magmatic and Tectonic Domains of Central Costa Rica and the Irazú‐Turrialba Volcanic Complex Revealed by Ambient Noise Tomography

Subduction driven processes in Costa Rica led to the development of volcanism, forming the active Central Costa Rican Volcanic Front (CCRVF). Located at the southernmost tip of the CCRVF is the active twin volcanic system, the Irazú-Turrialba Volcanic Complex (ITVC), 50 km north-east from Costa Rica's capital city, San Jose (Figure 1). The summits of each volcano are 10 km apart and form a complex that is about 60 km by 45 km at the base. To better understand these magmatic and tectonic domains, establishing the crustal structures beneath volcanic systems provides vital information into the implications of volcanism in Costa Rica.Despite being geographically close, the Irazú and Turrialba volcanoes undergo different eruptive cycles. This may partially be explained by the complex magmatic interactions between different reservoirs at depth as highlighted by geochemical and petrological data (Alvarado et al., 2006;DeVitre et al., 2019). Alvarado et al. (2006) suggest that Irazú is fed by two distinct magmatic reservoirs evolving in parallel and occasionally mixing. The

“…The great sensitivity of electronic tiltmeters enables the detection of micro-displacements that would otherwise be undetected by other monitoring sensors, such as GNSS or InSAR. In any case, tiltmeters should be an integral component of a geodetic monitoring system because of their low cost and great sensitivity (Battaglia et al 2021). Each CyCLOPS site is augmented by one (1) high-precision tiltmeter (Jewell D711-A-S), which has been clamped on the center pole of the monumentation to record even the smallest tilt deflection and check the stability of the reference station monumentation.…”

The objective of this paper is to introduce CyCLOPS, a novel strategic research infrastructure unit, and present its current progress of implementation, and integration in the National geodetic, geophysical and geotechnical infrastructure of the government-controlled areas of the Republic of Cyprus. CyCLOPS is co-funded by the European Regional Development Fund and the Republic of Cyprus through the Research and Innovation Foundation under the grant agreement RIF/INFRASTRUCTURES/1216/0050. CyCLOPS is developed via the collaboration of the Cyprus University of Technology (CUT) and the German Aerospace Center (DLR), and supported by the Cyprus Geological Survey Department and the Department of Lands and Surveys. The main objective of CyCLOPS is to establish an integrated infrastructure for space-based monitoring of geohazards using the most prominent earth observation technologies (EO), such as GNSS and InSAR. Furthermore, the infrastructure will densify and form the backbone for the definition of the next generation national datum of the Republic of Cyprus. Eleven Tier-1/2 state-of-the-art GNSS CORS, precise weather stations, tiltmeters and specifically designed InSAR triangular trihedral corner reflectors will be deployed, in a collocated fashion, at selected locations throughout the government-controlled areas of Cyprus. The collocated configuration will be established and installed to be compliant with the most stringent CORS monumentation specifications, support all current GNSS constellations and SAR missions. Finally, one of CyCLOPS’ fundamental aims is to actively contribute to the on-going efforts and growing demand for more precise positioning services and high-quality modern reference frames, in conformity with the recommendations of the UN-GGIM (and its Subcommittee of Geodesy) to establish and enhance national geodetic infrastructures to support the sustainable management of geospatial information on the changing Earth.
