Constraining earthquake fault sources through the use of intensity data and seismic scenarios: application to the Betic Cordillera (South Spain)

open access: yesFrontiers in Earth Science, 2023
Macroseismic observations can be useful to study pre-instrumental earthquakes when paleoseismological analysis are not viable for various reasons (e.g., erosion or lack of sedimentation).

Geological earthquake simulations generated by kinematic heterogeneous energy-based method: Self-arrested ruptures and asperity criterion

open access: yesOpen Geosciences, 2023
The lack of clarity regarding slip distribution within heterogeneous rupture areas has a significant impact on characterizing the seismic source and the role of heterogeneities in determining ground motion.

Generation of the Quaternary Normal Faults in the Messina Strait (Italy)

open access: yesGeosciences, 2023
It is widely recognized that since the Early–Middle Pleistocene, the Messina zone, the site of strong earthquakes, has undergone extension, but the geodynamic context which determined this deformation is still a matter of debate.

Models of the macroseismic field earthquakes and their influence on seismic hazard assessment values for Central Asia

open access: yesГеодинамика и тектонофизика, 2020
Seismic intensity assessment in points of a macroseismic scale plays an important role for researching the seismic history of areas characterized by active seismicity, as well as for construction (and updating) of seismic zoning maps in various scales ...

Influence of the Yucatan earthquake event

open access: yesFrontiers in Earth Science, 2023
In recent years, seismic wave effects caused by meteorite impacts have been widely observed. The meteorite impact event that occurred 66 million years ago is one of the most famous impact events in Earth’s history.

Interpreting intraplate tectonics for seismic hazard : a UK historical perspective [PDF]

open access: yes, 2012
It is notoriously difficult to construct seismic source models for probabilistic seismic hazard assessment in intraplate areas on the basis of geological information, and many practitioners have given up the task in favour of purely seismicity-based ...
