2016 Norcia earthquake (∆σ = 6.7 ± 0.8 MPa) is in agreement with the outcomes of previous studies investigating the difference of the reverse fault earthquakes in the Fri- uli region with respect to the normal faulting earthquakes typical of central Italy (Cocco and Rovelli ...
For the main shock, the focal mechanism solution obtained from the readings of first motion polarities of seismograms yields an ENE-WSW reverse fault dipping to the NNW, which is in good agreement with both field observations and the aftershock distribution at depth. The occurrence of the Mt ...

Reverse time migration of the tsunami signals can also be attempted, but the effective source time that must be assumed to form an image of the initial sea surface displacement is uncertain. There is also the large (14 min) time discrepancy for the one station to the north (Sand Point ...
Normal/reverse faulting components have been geodetically proposed to supplement major strike-slip faulting on EAF54. Non-uniform aftershock mechanisms13 indicate that even the mainshock might have included short segments that differ from strike-slip, similar to fault complexity which was indeed ...
The rake angle is allowed to vary between −45° and 45° where the strike-slip with normal or reverse components is incorporated. We calculated the Green's functions of azimuth offsets and tsunami waveforms under an assumption of faulting embedded in the elastic half-space theory (Okada, ...
This reverse force narrows the distance between the partials, diminishing gradually as the separation decreases (thereby reducing SF length). In a purely elastic scenario, the SF length will eventually recover to its initial state after unloading. In HEAs/MEAs, however, the scenario differs due to...
a positive change in the Coulomb failure stress transfer in a specific area is evaluated as an indication that a fault plane existing in this area has been driven extremely close to failure; on the other hand, if it decreased, the interpretation is the exact reverse situation (i.e., relaxed...
