Gas and seismicity within the Istanbul seismic gap [PDF]

Scientific Reports, 2018
Understanding micro-seismicity is a critical question for earthquake hazard assessment. Since the devastating earthquakes of Izmit and Duzce in 1999, the seismicity along the submerged section of North Anatolian Fault within the Sea of Marmara ...

Imaging overpressurised fracture networks and geological barriers hindering fluid migrations across a slow-deformation seismic gap [PDF]

Scientific Reports, 2023
There is an ongoing debate on the processes producing background seismicity and deformation transients across seismic gaps, i.e., regions that lack historical large-magnitude earthquakes.

B-value variations in the Central Chile seismic gap assessed by a Bayesian transdimensional approach [PDF]

Scientific Reports, 2022
The b-value can be used to characterize the seismic activity for a given earthquake catalog and provide information on the stress level accumulated at active faults.

Shallow slow earthquakes to decipher future catastrophic earthquakes in the Guerrero seismic gap [PDF]

Nature Communications, 2021
New offshore observations in the Guerrero seismic gap discovered shallow slow earthquakes, which suggest that a portion of the plate interface undergoes stable slip. This may explain the long return period of large earthquakes and why have previous large

Seismic swarms in the Pollino seismic gap: Positive fault inversion within a popup structure

Frontiers in Earth Science, 2022
Seismic swarms frequently occur along continental fault systems and their relation with large earthquakes is often contradictory. Such a case is documented in the Pollino mountain range of southern Italy, a decoupling zone where the belt-normal ...

An ANN-Based Approach for Prediction of Sufficient Seismic Gap between Adjacent Buildings Prone to Earthquake-Induced Pounding

Applied Sciences, 2020
Earthquake-induced structural pounding may cause major damages to structures, and therefore it should be prevented. This study is focused on using an artificial neural network (ANN) method to determine the sufficient seismic gap in order to avoid ...

Variation of Fault Creep Along the Overdue Istanbul‐Marmara Seismic Gap in NW Türkiye

Geophysical Research Letters, 2023
Strain energy from tectonic loading can be partly released through aseismic creep. Earthquake repeaters, repeatedly activated brittle fault patches surrounded by creep, indicate steady‐state creep that affects the amount of seismic energy available for ...

The 22 July 2020 M 7.8 Shumagin seismic gap earthquake: Partial rupture of a weakly coupled megathrust

Earth and Planetary Science Letters, 2021
The earthquake potential of the Shumagin seismic gap along the Alaska Peninsula (∼162°W to ∼158.5°W) has been debated for more than 40 years. On 22 July 2020, the eastern half of the gap hosted an M W 7.8 earthquake involving a patchy rupture of the ...

The Seismic Potential in the Seismic Gap Between the Wenchuan and Lushan Earthquakes Revealed by the Joint Inversion of Receiver Functions and Ambient Noise Data

Tectonics, 2018
Based on a dense seismic array deployed to monitor the seismic gap between the Wenchuan and Lushan earthquakes, a joint inversion of dispersion curves and receiver functions yielded a fine velocity structure in this region with the highest resolution of ...
