NEAREST - Integrated observations from NEAR shore sourcES of Tsunamis: towards an early warning system

NEAREST is addressed to the identification and characterization of potential tsunami sources located near shore in the Gulf of Cadiz; the improvement of near-real time detection of signals by a multiparameter seafloor observatory for the characterisation of potential tsunamigenic sources to be used in the development of an Early Warning System (EWS) Prototype;  the improvement  of integrated numerical models  enabling  more accurate scenarios  of tsunami impact  and the production  of accurate  maps  in selected areas of the Algarve (SW Portugal), highly hit by the 1755 tsunamis. In this area, highly populated and prone to devastating earthquakes and tsunamis, excellent geological/geophysical knowledge  has already been acquired in the last decade.
The methodological approach  will be based  on the cross-checking of multiparameter  time series acquired on land by seismic and tide gauge stations on the seafloor and in the water column  by broad band Ocean Bottom Seismometers  and a multiparameter  deep-sea  platform,  this latter equipped  with  real-time communication to an onshore  warning centre.  Land and sea data will be integrated to be used in a protptype of EWS.
NEAREST will search for sedimentological evidence of tsunamis records to improve the knowledge on the recurrence time for extreme events and will try to measure the key parameters for the comprehension of the tsunami generation mechanisms.
The prposed method can be extended to other near-shore potential tsunamigenic sources, as for instance the Central Mediterranean (Western Ionian Sea), Aegean Arc and Marmara Sea.
