Entry: seismological bedrock

URI: https://terra-vocabulary.org/ncl/DataTerraRepositoryFairIncubator/motsClefs/c_f4cc8d68

Depth of the seismological bedrock. Seismological bedrock corresponds to the geological unit that, because of the impedance contrast with the upper layers, controls the lowest (fundamental) resonance frequency peak; note however that some scientists consider the seismological bedrock as the crustal unit where the S-wave velocity is reaching a value between 3.5 and 4.0 km/s.
