  1. Seismic infrastructure in Spain: ROA A. Pazos, J. Martin Davila, E. Buforn, R. Cabieces, A. Strollo, M. Bezzeghoud, M. Harnafi, E.M. Lahcen and ROA seismic. ORFEUS Annual Workshop & Open EPOS Seismology meeting Lisbon, 25 - 27 October 2017

  2. Overview • The seismology in the ROA: brief history. • The Short Period Telemetric Network. • The Broad Band seismic network: Western Mediterranean (WM). • The ROA/UCM FOMAR OBS pool.

  3. THE SEISMOLOGY IN THE ROA: brief history. ROA was founded in 1753: Astronomy & navigation. 1898: Milne Nº. 6 Horizontal Pendulum (1st Spanish Seismograph). 1912: Two bifilar horizontal Graiño Seismograph and one vertical (1922). 1933: 3C Alfani type. 1966: 3C Spreghnether (IGN) . 1970: Benioff (1 sec). 1976: 3C 5100 type Spreghnether (ROA).

  4. THE SHORT PERIOD TELESEISMIC NETWORK 1986 Strait net (ROA+IGN+SECEG) complemented by ROA SP net. Goal: local seismicity around the Gibraltar Strait (Tunnel/Bridge). 9 Stations: Mark L4 sensor (1Hz). Analog data transmission (radio UHF/VHF). Digital conversion and storage at ROA data centre. Now a days stopped. NEAR FUTURE (<2020): Digital stations, short period response will be extended, digital TX. ARRAY?

  5. THE BB SEISMIC NETWORK: WESTERN MEDITERRANEAN (WM) First steps • 1996: BB station SFUC deployed by ROA+UCM+GFZ (MoU) at Cerro San Cristóbal (Jerez). Associated to GEOFON net. First steps • 1996: BB station SFUC deployed by ROA+UCM+GFZ (MoU) at Cerro San Cristóbal (Jerez). Associated to GEOFON net. First steps • 1996: BB station SFUC deployed by ROA+UCM+GFZ (MoU) at Cerro San Cristóbal (Jerez). Associated to GEOFON net. Standard WM Station: Sensor: Streckeisen STS2 or STS2.5. Episensor ES-T optional: EMAL, CART, MAHO, ARNO, AVE. Digitizer: Quanterra (Q330HR) or Earth Data (PS6-24). Comunications: Internet / Navy intranet / VSAT.

  7. The ROA/UCM FOMAR OBS pool. Composed by 6 (1 lost) BB LOBSTER-6000 OBS: • Sensor: CMG-40T or Trillium Compact. • Hydrophone. Last ROA campaign: • SW San Vicente Cape (Spanish Navy ships). • September 2015 – April 2016 OBS05 LOST • No acoustic response. • No surface after release. • No surface after programmed release.
