What is it? LISARD is a seismological array of 10 broadband seismic stations
10 posthole nanometrics broadband (120s) sensors have been installed at the end of June 2016. We follow the AlpArray recommendations for procedures and data
Why? Improving knowledge of the geological evolution of Sardinia is key for understanding the Mediterranean geodynamics processes.
Being not very active seismically, there is a lack of seismic coverage in Sardinia and, consequently, poor information on deep crustal and lithospheric mantle structure.
Our array will remedy this and provide better coverage of the Tyrrhenian Sea.
What kind of science? Seismic data will be processed to extract surface-wave dispersion curves from ambient noise and to extract receiver functions, i.e. converted and reflected waves from major discontinuity below the stations.
We will jointly interpret the data using a transdimensional inversion approach. We wil include petrology constraints in our model.
The seismic data will be also used to improve coverage of existing surface-waves models of Tyrrhenian sea and to detect possible microevents.
