The proposed study consists in the direct measurement and modelling of the Local Solid Earth Tides (LSET) effects using GNSS observation Series. Analysing the variability, amplitude and frequency of the tidal effects observed in the GNSS observations it is intended to characterize and model the crustal response in the location of the GNSS receiver stations. Later, in the cases where it can be feasible, the relation of these effects with seismic and volcanic events occurring close to the used GNSS receiver stations network will be analysed.
Infact we will study the correlation between LSET and geological events such as tectonic displacemnts, earthquakes and volcanic acticities, through use of GNSS.
So, the main objectives of this activity are:
- Extraction and analysis of LSET effects from GNSS measurement series taking into account also ocean loading effects if relevant;
- Definition of a solid tide correction strategy for GNSS based on local tide effects for PPP and GNSS orbit determinations;
- Deriving the relation between LSET measurements and models with seismic and volcanic events occurring in or close to the used GNSS receiver stations;
- Based upon the derived relation analyse and describe possible potential for forecast and assessment of the risk of geologic hazards.
The project is being coordinated by DIAN S.r.l. and will last for 15 months.
