The 18th International Symposium on Geodynamics and Earth Tides 2016 covered phenomena that
generate temporal variations in geodetic and geophysical observations. In calculating the stress
field for Earth tides, the observed geodetic response is used for defining the Earth's rheology, the Earth internal
structure, Earth rotation parameters, and the functioning of the sophisticated instrumentation mounted
on Earth and satellites. The instrumentation capable of observing Earth tides, measures changes
generated by lithospheric plate movements, as the earthquake cycle and volcanism. Hydrology, tem-
perature, and pressure, either of natural or anthropogenic origin, affect the high precision observations,
and therefore must be included in this study-realm.
