Faulty Assumptions Impair Earthquake Hazard Assessment in Italy

Faulty Assumptions Impair Earthquake Hazard Assessment in Italy

New publication!

It has finally published on Tectonophysics a new paper published with collegues of University of Pavia and University of Trieste.
The paper is entitled "The effects of pre-existing discontinuities on the surface expression of normal faults: Insights from wet-clay analogue modeling" and explore how the presence of pre-existing discontinuities, either structural or sedimentary, can influence the growth of a normal fault and what can be their surface expression at the different evolutionary stages.

You can find the paper at the following address on the journal webpage:

This is the graphical abstract of the paper (taken from the journal webpage)













Highlights

• We use wet-clay analog models to simulate isolated initially-blind normal faults.
• We analyze the interaction of surface normal faults with inherited discontinuities.
• Inherited discontinuities strongly affect fault development at the Earth's surface.
• The influence of a discontinuity strongly depends on its orientation relative to the fault.
• We provide a ranking chart to assess fault-to-discontinuity interactions.
