Land subsidence is a natural hazard that sometimes causes significant economic damage and great alarm. The causes of land subsidence are diverse and sometimes complex, and all lead to vertical deformations of the earth’s surface. These deformations can range from a few millimetres to several meters for periods ranging from minutes to years. This paper, in association…
Displacements and ground motions near volcanoes are one of the warning signs of volcanic eruptions. One of the most important tools to detect such movements is the technology provided by GNSS permanent stations network. This paper, in association with Albireo Topografia y Geomática, studies the use of GNSS techniques for the determination of the spatial and temporal displacements…
Sixty per cent of human deaths caused by natural disasters in the past decade were due to earthquakes. Earthquake monitoring has assumed great importance in recent scientific studies and one of the most recent additions to the numerous inter-disciplinary techniques employed for studying earthquakes are GNSS technologies. GNSS technologies and permanent station networks have created…
One of the effects of earthquakes is the permanent displacement of the areas near the epicentre. Global navigation satellite system (GNSS) technologies and gnss permanent stations networks have created a tool and an essential terrestrial reference frame for the study of those displacements. This paper, in association with Albireo Topografia y Geomática, aims to use GNSS…
