Geophysical Monitoring


Seismic monitoring

The data from the COI seismic station are currently included in the national seismic monitoring network (operated by IPMA), but are also part of several networks / infrastructures for the analysis and dissemination of international seismic waveforms (Orfeus, IRS). At present Orfeus has a platform where you can see in real time some of the digital stations that are associated with it. COI station is one of them, you can see the real-time registration of one of the station's components at https://www.orfeus-eu.org/data/odc/realtime/ . The COI station is currently equipped with a Streckeinsen STS-2 broadband, which records seismic vibrations in three components, i.e. two horizontally components oriented perpendicularly (NS (N) and another EW (E)) and a vertical component (Z). The station registers each of the three components in three bands (H, B, L). At the Orfeus, only the H band (HHN, HHE, HHZ) is visualized in real time. Since global seismic stations always use UTC (Coordinated Universal Time), there may be a time offset of 1 hour from local time.
