Volcano-tectonic dynamics of Deception Island (Antarctica): 27 years of GPS observations (1991–2018)

Recent local geodynamic processes in the Penola Strait_Lemaire Channel fault area (West Antarctica)

“…However, Berrocoso et al (2016) inferred absolute vertical velocity vectors indicate subsidence in the north-eastern part of the South Shetland Islands archipelago in contrast to the uplift movement observed by Dietrich et al (2004), but in agreement with the data published by Jiang et al (2009) and Bevis et al (2009). In Rosado et al (2019) GNSS observation on 15 stations were used in the island's tectonic and volcanic rocks behaviour on Deception Island (West Antarctica). The obtained results demonstrate that Deception and Livingston Islands have a similar behaviour derived from the Bransfield Basin extension and the Phoenix micro-plate I.…”

Analysis of Different GNSS Data Filtering Techniques and Comparison of Linear and Non-Linear Times Series Solutions: Application to GNSS Stations in Central America for Regional Geodynamic Model Determination

“…With regard to geodetic control, the variations of the absolute coordinates obtained through a geodetic calculation and adjustment process are analyzed in both Cartesian coordinates (X, Y, Z) and topocentric (east, north, up) using different techniques that guarantee millimeter-level precision to provide optimal results for regional tectonic or volcanic surface deformation parameters [10] of the region. This implies the use of precise auxiliary parameters such as precise ephemeris, corrections of the satellite clocks and the tropospheric models, as well as data processing and filtering methods capable of jointly managing the results.…”

Improving geodynamic monitoring practice in underground gas storage areas

“…Aggravation of induced seismicity, abnormal deformations of the earth's surface, integrated environmental effect of geodynamic processes [10][11][12][13][14][15][16][17][18][19] are observed in mining regions. Taking into account current understanding of the hierarchical-block structure of the rock [3,[20][21][22] ] the presence of regional and local tectonically stressed and unloaded zones therein, including zones of critical stress [23], achievement in field of monitoring [24][25][26][27] it can be assumed that the inclusion of engineering facilities such as UGSs into this natural system can also lead to their geodynamic interaction and mutual influence. It is important to know that the costs involved in impact analysis of natural and man-made phenomena, as well as systematic monitoring are hugely less than those involved in emergency response and remediation.…”
