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.
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
