CityShark, a station dedicated to ambient noise (microtremor) recording, was designed and built jointly by the French Institute for Research for Development (IRD) and LEAS, a French company dedicated to geophysical data acquisition.

Because portable seismic stations are designed to be installed for long time periods (days to months) and to detect earthquakes, operators using them for microtremor recording face several obstacles that considerably slow and complicate the data acquisition process. Seismological stations are not easy to use in experiments for which time of recording is on the order of tens of minutes (site studies) or for repetitive recording of...
