The volume collects papers submitted to Pure and Applied Geophysics following a call on the topic “Geodynamics and Earth Tides”. Partly, the authors had participated in the 18th Geodynamics and Earth Tides Symposium held in Trieste, Italy, in June 2016. The Earth tides constitute the leading thread through the book, since instrumentation sensitive enough to observe them, also records a broad spectrum of signals generated by Earth dynamic processes.
