  Spin-2, spin-1 and spin-0 modes in linearised teleparallelism are obtained
where the totally skew-symmetric complex contortion tensor generates scalar
torsion waves and the symmetric contortion in the last two indices generates
gravitational waves as gravitational perturbations of flat spacetime with
contortion tensor. A gedanken experiment with this gravitational-torsion wave
hitting a ring of spinless particles is proposed which allows us to estimate
the contortion of the Earth by making use of data from LISA GW detector. This
value coincides with previous value obtained by Nitsch in teleparallelism using
another type of experiment.
