Sismicidad, Sismotectónica Y Riesgo Sísmico (Sisris)

The Research Group of "Sismicidad, Sismotectónica y Riesgo Sísmico" belongs to the Department of Earth"s Physics, and Astrophysics from the Faculty of Physics of UCM. This group has a long experience in studies Earth"s Science disciplines, such as seismicity, focal mechanism of earthquakes, and seismic hazard. This research group was pioneer in proposing seismotectonic models for the Azores-Gibraltar region. More recently, two new research lines have been developed: Earth"s Inner Core Structure and Earthquake Early Warning Systems (EEWS). The anisotropy and hemispherical dichotomy of the Earth"s Inner Core has been the focus of an intense scientific activity that gave rise to novel mineral physics scenarios and specific model velocities for the solid Earth"s core. This group has also studied the feasibility of an EEWS for the Ibero-Maghrebian region, developing specific correlations for the region in order to give an alert. In collaboration with the Spanish Army (Real Instituto y Observatorio de la Armada, ROA) the group has deployed a seismic network of broadband stations in land (Western Mediterranean network formed by 18 stations) to cover the region between South of Spain and North Africa and the group have the FOMAR Ocean Bottom Seismometer (OBS) network for temporary surveys. Researchers from this Group have developed a long tradition in collaborating with most of the important national and international institutions in the field of seismology.

Historical and instrumental seismicity. <br />Re-evaluation of damage, intensity maps and attenuation laws. <br />Study of attenuation. <br />Hypocenter locations using non-linear methods and observations in land and OBS.<br />Rupture process of earthquakes. <br />Determination of focal mechanism using point and extended sources.<br />Inversion of seismic momento tensor at teleseismic and regional distances. <br />Empirical Green functions and directivity effects. <br />Application to shallow, intermediate and deep earthquakes. <br />Seismotectonic models.Earthquake Early Warning. <br />Empirical correlations for the Ibero-Maghrebian region. <br />Focal mechanism and EEWS parameters. <br />Estimation of threshold values for EEWS. <br />Another line of investigation here refers to the study of both anisotropy and hemispherical dichotomy in the Earth"s Inner Core by bridging together high quality inner core probing seismic data and model sound velocities from first-principles molecular dynamics calculations. Such a multidisciplinary line of research is seeking to find the best mineral physics scenario for the Earth"s inner core, so as to achieve a deeper understanding of the mechanisms that are governing the thermo-chemical evolution of our planet.<br /><br />
