Tide guages Network in the Gulf of Cadiz zone
Map displaying MWH along the Gulf of Cadiz
coasts considering all the tsunamigenic
scenarios, existing and 4 additional tide gauge
stations (TG1 to TG4 in red dots) recommended for
the region.

Tsunameters design for the Gulf of Cadiz region
The study adopts a specific strategy for
tsunameter installation based upon three main
criteria (i) maximization of warning time,
(ii)coverage of all the area where tsunami can be
detected and (iii) the conditions of
installation flat bottom topography and a safe
distance from the seismic source for station
location
Established tunameters monitoring network for the
Gulf of Cadiz region. White stars are the
recommended positions for DART-like sensors in
the area. Graphs illustrate waveforms recorded by
the proposed DART-like network only waves
detected in the time interval of 0 -10 minutes
after the tsunami occurrence are considered.

Computed TAT to the proposed tsunameters (DART1,
DART2 and DART3) and to different points along
the Gulf of Cadiz coasts

Warning time considering the proposed tsunameters
design
Warning Time along the coasts in Portugal, Spain
and Morocco, considering that the 3 DART systems
proposed are available (red dots)
