Description |

The COI seismic station, situated in Coimbra, Portugal, holds the distinction of being the oldest seismic station in mainland Portugal and one of the world's most ancient. It commenced continuous recording in 1903 using a Milne horizontal seismograph. Today, seismic recording continues at this historic site with a broadband Streckeisen STS-2 seismometer, which has been in use since 2007; for further historical information see: Custódio et al. 2012, doi: 10.1785/0220120014 |
