Obtaining the maximum possible outcome out of an
extremely-light equipment and limited field effort.
The proposed system consists of:
- a (good quality) 4-channel seismograph;
- one 3-component (3C) geophone;
- four vertical geophones.
The system (after the van der Rohe’s motto “Less is More”):
minimalistic elements with multiple functional purposes
Less is More (Dal Moro et al., 2015) – GNGTS 17-19 November 2015 – Trieste (Italy)
The acquired (active and passive) data, are used to determine
up to six (now actually seven) independent (but mutually
related and complementary) objective functions that, all
together, fully describe the surface-wave propagation.

Questioning the multi-channel dogma:is the analysis of phase velocity (analyzed via multi-channel data) better with respect to the single-channel data useful for the analysis of group velocities?
