Supplementary Dataset for the Report "Imaging the Western Edge of the Aegean Shear Zone: The South Evia 2022-2023 Seismic Sequence"
<p>Supplementary Dataset for the Fast Report "<strong>Imaging the Western Edge of the Aegean Shear Zone: The South Evia 2022-2023 Seismic Sequence</strong>" by Christos P. Evangelidis and Ioannis Fountoulakis.</p> <p>The Fast Report can be found in <em><strong>Seismica Vol. 2 No. 1 (2023)</strong></em>.</p> <p><strong>DOI:</strong> <a href="https://doi.org/10.26443/seismica.v2i1.1032">https://doi.org/10.26443/seismica.v2i1.1032</a></p> <p><em><strong>Abstract:</strong></em></p> <p>This report presents the 2022-2023 South Evia island seismic sequence, in the western Aegean sea. An automated workflow, undergoing testing for efficient observatory monitoring in the wake of dense aftershock sequences, was employed to enhance the seismic catalog. It includes a deep-learning phase picker, absolute and relative hypocenter relocation, and moment tensor automatic calculations. The relocated catalog reveals a concentration of earthquake epicenters in a narrow NW-SE zone, with sinistral strike-slip fault movement. The findings of the study indicate the occurrence of an asymmetric rupture within conjugate fault structures in the western Aegean region. These fault structures, although not necessarily both active, play a significant role in marking the transition from dextral (SW-NE) to sinistral (NW-SE) strike-slip ruptures, connecting the Aegean shear zone with normal faulting in mainland Greece. The South Evia 2022-2023 seismic sequence has revealed the activation of this NW-SE strike-slip structure, contrary to previous assumptions of low seismicity in the region. The study highlights the importance of reassessing seismic hazard maps and considering the potential activation of similar zones further south in the future. It also emphasizes the need for the expansion and the densification of seismic networks within the Aegean.</p> <p><em><strong>Files:</strong></em></p> <p><strong>Relocated_Catalog.txt</strong>: Relocated earthquake catalog for the South Evia sequence.

A new lithospheric density and magnetic susceptibility model of Iran, starting from high resolution seismic tomography
<p>The Iranian collisional belt formed through different geological events, some of which are still in progress, such as the convergence between Eurasian and Arabian plates, that led to the formation of a complex structure throughout the entire area. To better investigate these structures, we realize a 3D model of the lithosphere in Iran showing the density and the magnetic susceptibility distribution, obtained from a Bayesian joint gravity and magnetic field inversion, starting from a high-resolution seismic tomography (Kaviani et al., 2020). With these models we also calculate the rigidity distribution of the area. The Data Cube uploaded contains the density, magnetic susceptibility and shear modulus volumes, the Bouguer gravity field and the magnetic field, and the Moho, Curie depth and sediment base depth surfaces.</p>
Pre-CSRM: A 3-D seismic model of the shallow crust in continental China
<p>This high-resolution shallow three-dimensional seismic model is constructed for the top 10 km of the upper crust in continental China, based on the constraints of P polarization, Rayleigh wave ellipticity and receiver function obtained from records of <strong>3848</strong> seismic stations during 1990 and 2017. The model has a spatial resolution of 0.3 degree * 0.3 degree in the north-south seismic belt and the trans-north China orogen, and 0.5 degree * 0.5 degree in the rest of continental China (except the Tarim basin and southwest Tibet with no station coverage). The seismic constraints used for the construction of the model consist of the <strong>5,439,702</strong> polarization angle measurements from the P-wave waveforms of 9361 tele-seismic earthquakes, the short-period (4 - 8 s) Rayleigh wave ellipticity estimated from the continuous waveforms of seismic ambient noise, and the stacked receiver functions estimated from <strong>2,125,021</strong> original receiver functions calculated based on the waveforms of 9361 tele-seismic events.

Rupture Jumping and Seismic Complexity in Models of Earthquake Cycles for Fault Stepovers with Off-Fault Plasticity
<p>Fault stepovers are prime examples of geometric complexity in natural fault zones which may affect seismic hazard by determining whether an earthquake rupture continues propagating, or abruptly stops. However, the long-term pattern of seismicity near fault stepovers and underlying mechanisms of rupture jumping in the context of earthquake cycles are rarely studied. Leveraging a hybrid numerical scheme combining the finite element and the spectral boundary integral methods, FEBE, we carry out fully dynamic simulations of Sequences of Earthquakes and Aseismic Slip (SEAS) for both compressive and tensile stepovers, with off-fault plasticity. We consider a rate-and-state friction law for the fault friction, and pressure sensitive Drucker-Prager plasticity for the off-fault bulk response. We observe that the accumulation of plastic deformation, an indication of off-fault damage, is significantly different in the two cases with more plastic deformation projected in the overlapping region for the tensile stepover. The seismic pattern for a tensile stepover is more complex than for a compressive stepover, and incorporating plasticity also increases complexity, relative to the elastic case. A tensile stepover with off-fault plasticity shows rupture segmentation, temporal clustering, and frequent rupture jumping from one fault to another. These results shed light on possible mechanisms of rupture jumping in fault stepovers as well as the long-term evolution of the fault zone.</p>
