Acoustic signature of fault slip from slow to fast earthquake: a laboratory insight
FROM ROCK PHYSICS TO EARTHQUAKE MECHANICS: INSIGHTS FROM THE FIELD, THE LAB, AND IN BETWEEN II POSTER
mineral and rock physics | 15 december 2022
Federico Pignalberi, Marco Maria Scuderi, Carolina...
In the last decades, it has been observed that faults can slip both by slow aseismic creep and seismic events (i.e., earthquakes). In between these tw...
