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

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.

WP5: Rabat Data Collector
Acquisition and installation of near real time digital tide gauge

The development of the Early Warning System (EWS) Prototype is
based on the integration of




Actually there is a lack of coverage by real time tide gauge of the
southern part of Moroccan-Iberian region


land recorded seismic data
deep ocean water height
near-shore tide gauge data.
the localisation in morocco of a new real time tide gauge will fill the
lack and will improve greatly the reliability of the Tsunami early
warning System prototype
CNRST contribution to development of TEWS by acquiring a digital
tide gauge



Near shore Sea level data transmitted in near real time to Rabat
data collector
Availability Data in near real time to others data collector
Installation planned in less than 3 months in Moroccan Atlantic cost

Moroccan tide gauge network
ANP: 10 Tide gauges:
-VEGAPULS 65 Radar Sensor
-AURORE 200 datalogger.
Martec/Serpe-IESM
-Data is recorded every 10
minutes but presently only a
Flash memory is used
-Data sent as an attachment to
an email on a monthly or 3
monthly period from all ports
ANCFCC: 2 Tide gauges
- Mors HT200 Acoustic
- No information availaible on
data storage and transmission
Moroccan tide gauge network operated since 2003 by DPDPM and ANCFCC.

CNRST- ANP BEGINNING OF
COOPERATION

Possibilities of cooperation on tsunami hazard assesment
(accses to ANP tide database)

Installation of CNRST TG in Harbour managed by ANP

data exchange in real time between CNRST and ANP

CNRST can take in charge upgrading of data transmission
possibilities of the current tide gauge in tangier

it will result in two real time TG for the benefit of our
NEAREST project
