The seismological arrays

•   U. of Athens station
•   NOA station
•   CNRS station
• U. of Patras station

Network description

• CRLNET is composed of 11 stations equipped with 2Hz seismometers, 9 stations equipped with broad band seismometers, recording continously at 100 Hz and one antenna of 7 broad band stations. CNRS (France) is running 14 stations and the antenna, Patras University 4 stations and Athens University 2.
• 5 seismometers on the south shore of the gulf are in 60-100 m deep boreholes (AIOA, ALIK, AGEO,DIMT, TEME). MALA located on the Mornos delta on the north shore is in a 190 m deep borehole. 
• All stations are transmitted in real time and merged to provide real time earthquake location. 
• Data are available since April 2000.
• View real time recordings
• View real time locations
• Access revised automatic catalogs and seismicity maps
• Access CUP (Charles University of Prague) database

Acces to waveform data

• The seismological/deformation network is operated by different institutions and therefore associated with different network codes. The present configuration is :
  • code HP : SERG, ANX, PVO, EFP, VVK ; doi:10.7914/SN/HP ; University of Patras
  • code HA : LAKA, KALE ; doi:10.7914/SN/HA ; Kapodastrian University of Athens
  • code HL : KLV, RLS, DLFA ; doi:10.7914/SN/HL ; National Observatory of Athens
  • code CL : all CNRS stations ; doi: 10.15778/RESIF.CL ; Citing instructions are given in ; Centre National de La Recherche Scientifique

• A virtual network code _NFOCRL is maintained at EIDA-NOA data center and includes all stations located inside the large frame of CRL Laboratory. A global request can be done using this virtual network code. Attention : presently only the ArcLink procedure is operational at NOA server (eida.gein.noa.gr:18001) for the virtual network code, FDSN web services will be operational in the future.

Data are archived at:

– NOA data center for the HP, HA, HL network codes.

– RESIF data center for the CL network code.

• Real time and quality controled data are available on EIDA european servers. This concerns all velocity and acceleration chanels. Soon deformation and tide gauge will be added.
• Requests tools are the classical tools of the seismological community :

 – Near real time data with seedlink at rtserve.resif.fr (TCP port 18000) for CL data. Documentation

– Arclink node :eida.resif.fr (TCP port 18001) or eida.gein.noa.gr (TCP port 18001). Documentation

– FDSN web services at ws.resif.fr/fdsnws (TCP port 80) or eida.gein.noa.gr/fdsnws/ (TCP port 80). Documentation

– Web tool at eida.gein.noa.gr/webdc3/ or Orfeus data center.

Data before 2010 are progressively added to the database. All HA and HP stations with the _NFOCRL will be progressively added in EIDA@NOA. CL data between 2000 and 2010 are added progressively to the RESIF database. CL real time data are qualified and completed when possible within a delay of one year.
