Many solution cavities ranging from small voids to full-size caves have no entrances and therefore no access from the surface. Geophysical methods can be used, with varying degrees of reliability, to detect such cavities and can also provide information on the bedrock/regolith interface. These methods include microgravity, electrical resistivity, audio-magnetotelluric soundings, ground-penetrating radar, shallow seismic probes, synthetic aperture radar, and thermal probes. Magnetic induction (cave radio) can provide precise locations of underground passages if they have a surface access.
