Abstract
We investigate the use of seismic sensors as small seismic sources. A voltage signal is applied to a number of geophones, forcing the mass within the geophones to move, generating a seismic wavefield that is recorded on a separate array of geophones. We observe higher-frequency (25 Hz and above) surface and body waves propagating from the geophone source at offsets of 10s of metres.
