MC seismic gaining momentum in China thanks to digital accelerometers.

As a leading provider of land recording systems, we had the opportunity to contribute to the spectacular<br>growth of land multi-component (MC) projects in China fostered by the availability of the new three<br>component (3C) digital accelerometers. We present in chronological or geographical order the fast<br>development of MC acquisition that is illustrated by typical examples. Then, a summary showing the<br>general characteristics of these surveys is proposed, as well as the difficulties in processing and<br>interpreting these datasets.
