Abstract
The study of seismic activity has played a key role in increasing the understanding of the dynamics of the Earth and its internal structure. Variations in
real time seismicity provides knowledge of the state of local and regional stresses in the short and medium term, essential information to study the
potential seismic risk that may affect infrastructures and population located in the area . Seismic information is obtained indirectly from the knowledge of
traveling time of seismic waves and their trajectories. For this, it is important to record these waves with different azimuths using seismic sensors. The
resolution of these measurements depends on the coverage and number of sensors capable of recording these waves and their arrival times. On land,
the resolution, and coverage is adequate at the regional level, and is relatively easy to be increased in specific cases using portable seismic stations
(e.g. for microseismic studies). However, it is important to note that the dynamics of the lithosphere associated with the interaction of tectonic plates
happens mostly in ocean basins and margins, yet the distribution of marine seismic stations is far from their equivalent in land, either because of the
technological complexity related with the environment, or the difficulties to access the recorded data. Recent seismic activity, possible induced, in the
Gulf of Valencia or the intense underwater seismic activity associated with the eruption of El Hierro (2011-2012) shows the importance of controlling the
seismicity located in the sea that is not covered by the terrestrial monitoring networks.
To overcome this problem, the INTMARSIS project will integrate different measurement and data communication technologies in a new design with a
buoy on surface and a seafloor seismometer. The integration of real time data generated by marine seismometers will be possible thanks to the
development of wireless communication systems, the increasing potential for miniaturization of sensors, storage devices and data processing, which
have opened the door to a new generation of distributed intelligent sensor networks that are connected by communication networks.
To enable the exchange of instruments between different systems and platforms is necessary the standardization of these. Therefore, standardization
should begin at the sensor level because this gives a good integration of the information flow. In observing systems with a limited number of instruments,
it is always possible to individually integrate each instrument in the measurement system. However, in the future systems of heterogeneous observation
and dynamic variable, this concept will not be practical.
The joint efforts of the research team, and industrial EPOs with extensive experience in the various technological challenges of the project, will permit the
design, construction and assembly of a new generation of interoperable marine seismometers that will delivered acquired information in real time. This
will represent a significant advance over existing devices, decreasing the technological dependence and promoting the development of own technologies.
