This study estimates source properties by analyzing seismic data of 303 earthquakes (2018–2020) in the Marmara Region, Turkey, and finds a strong correlation between moment-derived coda magnitude (M_w-coda) and moment magnitude (M_L). Moreover, the scaled energy increases with seismic moment estimates and shows non-self-similar scaling in earthquake sources.

We postulate that the observed spatial distribution of large earthquakes in active convergence zones, organised in segments where large events are repeated every 100–300 years, depends on large-scale continental faults and fluid release from the subducting slab. In order to support this model, we use proxies at different spatial and temporal scales (historic seismicity, megathrust slip solutions, inter-seismic cumulative seismicity, GPS/viscous plate coupling, and coastline morphology).

Reconstructions of past earthquakes are useful to assess earthquake hazard risk. We assess a limestone scarp exposed by earthquakes along the Sparta Fault, Greece, using ³⁶Cl and rare-earth elements and yttrium (REE-Y). Our analyses indicate an increase in the average scarp slip rate from 0.8–0.9 mm yr^-1 at 6.5–7.7 kyr ago to 1.1–1.2 mm yr^-1 up to the devastating 464 BCE earthquake. REE-Y indicate clays in the fault scarp; their potential use in palaeoseismicity would benefit from further study.

This study investigates how Earth's geodynamic processes shaped the NW Zagros mountain belt in the Middle East. The Neogene foreland basin underwent subsidence due to the load of the surface and the subducting slab and was later influenced by the Neotethys horizontal slab tearing and the associated asthenospheric mantle flow during the Late Miocene and onward.

The STAR project set out to drill six shallow holes and use geophysical logging to find the best depth for placing seismometers and strainmeters to image the upper crust, in particular the Alto Tiberina fault, Italy. These measurements give us a better idea of what the rocks are like, helping us connect what we know from the literature with what we find underground, giving solid information on rock properties, which helps us understand the first few hundred meters of the Earth's crust.
