NEAREST meeting Barcelona May 2008 Workpackge N° 5 Data integration/ Integrated tsunami detection Network Objectives: Integration of data collected in real time, collection of waveforms from different permanent landbased networks with the data collected by OBS array and seafloor observatory Description of work Task 5.1: Establishment of 3 data collectors for real-time automatic processing of data (one in Portugal, the other in Spain and a 3rd one in Morocco) Task 5.2: Waveform sharing between data collectors, integration of seismic data including OBSs Task 5.3: Integration of tide gauge data Task 5.4: Integration of multiparameter data from seafloor observatory Task 5.5: Development of automatic procedures for rapid determination of seismic parameters and definition of thresholds for triggering the tsunami detection procedures Task 5.6: Development of an effective tsunami detection methodology. Definition of thresholds for issuing different levels of alarm messages

NEAREST meeting Barcelona May 2008 Contribution of the CNRST to WP5: Seismic Data sharing and integration: current state CNRST-Rabat reception from IM of Lisbon since 20/5/08 PM_PVAQ BB station (since 20/5/08) Digitiser: Guralp DM24 Sensor: Guralp CMG-3T (120 sec) PM_PESTR BB station (since 20/5/08) Digitiser: Guralp DM24 Sensor: Guralp CMG-3T (120 sec) PM_PFVI BB station (since 18/11/08) Digitiser: Guralp DM24 Sensor: Guralp CMG-3ESPc (120 sec) IM of Lisbon reception from Rabat RTC-Rabat VBB station (since 20/5/08) Digitiser: Quanterra 680 Sensor: VBB Streikeisen STS-1 (320 sec) One or two news BB stations wil be availaible in few months to IM and UGR nodes Data sharing with UGR regional center of Spain (node): not yet available because data acquisition system in Spanish node is based on another system not compatible with Seiscomp. In few months this problem will be fixed and 2 BB stations will be availaible in real time to Rabat node.
