Performance of base-isolated moment resisting steel frames subjected to pounding effects under near-field earthquake ground motions [PDF]

Journal of Structural and Construction Engineering, 2021
Despite conservative requirements of existing building code regarding clear seismic gap distance of base-isolated (BI) structures to surrounding moat walls, seismic performance of these structures is still ambiguous under severe earthquake ground motions

THE PROBABILITY OF A STRONG (M≥6.0) EARTHQUAKE IN THE SOUTH FERGANA SEISMIC ACTIVITY ZONE IN THE COMING YEARS

Геодинамика и тектонофизика, 2023
There were investigated seismic mode and stress state of the Earth’s crust in the South Fergana seismic activity zone. In the central part of the zone, there was identified an area of a long-term seismic quiescence during which no earthquakes with energy

Long silence on the East Anatolian Fault Zone (Southern Turkey) ends with devastating double earthquakes (6 February 2023) over a seismic gap: Implications for the seismic potential in the Eastern Mediterranean region

Journal of the Geological Society, 2023
On the 06th February 2023, an earthquake with magnitude ∼Mw7.0 on the Narlı Fault, a fault subparallel to the East Anatolian Fault Zone (EAFZ), initiated a chain of large earthquakes on the EAFZ.

Relation Between Oceanic Plate Structure, Patterns of Interplate Locking and Microseismicity in the 1922 Atacama Seismic Gap

Geophysical Research Letters, 2023
We deployed a dense geodetic and seismological network in the Atacama seismic gap in Chile. We derive a microseismicity catalog of >30,000 events, time series from 70 GNSS stations, and utilize a transdimensional Bayesian inversion to estimate interplate

Stress Evolution Before and After the 2021 Mw 7.3 Maduo Earthquake in Northeastern Tibet and Its Influence on Seismic Hazards

Earth and Space Science, 2022
The 2021 Mw 7.3 Maduo earthquake ruptured the Kunlun Pass‐Jiangcuo fault (KPJF) in the Bayan Har Block (BHB) in northeastern Tibet. To explore the reasons behind the Maduo earthquake and the seismic hazards that followed this event in the BHB, we ...

Variations of the seismic b-value along the Dead Sea transform

Frontiers in Earth Science, 2022
The frequency-magnitude distribution follows the Gutenberg-Richter empirical law, in which the scaling between small and large earthquakes is represented by the b-value.

Testing of the Seismic Gap Hypothesis in a Model With Realistic Earthquake Statistics

Journal of Geophysical Research - Solid Earth, 2022
The seismic gap hypothesis states that fault regions where no large earthquake has recently occurred, are more prone than others to host the next large earthquake.

Seismic gaps and earthquakes [PDF]

Journal of Geophysical Research: Solid Earth, 2003
McCann et al. [1979] published a widely cited “seismic gap” model ascribing earthquake potential categories to 125 zones surrounding the Pacific Rim. Nishenko [1991] published an updated and revised version including probability estimates of characteristic earthquakes with specified magnitudes within each zone.

Seismic Activities and Hazards of the Seismic Gaps in the Haiyuan Fault in Northeastern Tibet: Insights From Numerical Modeling Earthquake Interaction

Earth and Space Science, 2022
The 2022 Mw 6.6 Menyuan earthquake occurred in the Qilian‐Haiyuan fault system in northeastern Tibet. To investigate the mechanism behind the 2022 Menyuan earthquake and the seismic hazards (SHs) of the Tianzhu seismic gap, the spatiotemporal stress ...

Radial Gradient Seismic Metamaterials with Ultra-Low Frequency and Ultra-Wide Band Gap

Applied Sciences, 2023
In this paper, a radial gradient seismic metamaterial (RGSM) is proposed. The structural unit cell is composed of an external square soil embedded with a triangular-cross-sectioned steel ring, which is filled at different angles of multiple steel rings ...
