Clustering Analysis of Seismicity in the Anatolian Region with Implications for Seismic Hazard

open access: yesEntropy, 2023
The Anatolian region is one of the most seismically active tectonic settings in the world. Here, we perform a clustering analysis of Turkish seismicity using an updated version of the Turkish Homogenized Earthquake Catalogue (TURHEC), which contains the ...

Optimum b value for resolving crossing fibers: a study with standard clinical b value using 1.5-T MR [PDF]

open access: yesNeuroradiology, 2010
We sought to investigate the optimum b value for resolving crossing fiber using high-angular resolution diffusion imaging (HARDI)-based multi-tensor tractography. The study tested the standard b values that are commonly used in the routine clinical setting.Ten normal volunteers (five men and five women) with a mean age of 26.3 years (range, 22-32 years)

Acoustic Emission Analysis of Fracture and Size Effect in Cementitious Mortars

open access: yesApplied Sciences, 2022
The size effect is a phenomenon where the strength and the ductility of a material depend on the size of the structure. Investigating size effects and related crack formation in brittle materials requires advanced monitoring methods.

Entropy, energy, and proximity to criticality in global earthquake populations [PDF]

open access: yes, 2002
We examine the question of proximity of the global earthquake population to the critical point characterised by the energy E and entropy S based on annual frequency data from the Harvard CMT catalogue.

The 2022 Mw6.2 Pasaman, Indonesia, earthquake sequence and its implication of seismic hazard in central-west Sumatra

open access: yesGeoscience Letters, 2023
The 2022 Mw6.2 Pasaman earthquake took place in central-west Sumatra in association with activity in the Sumatran Fault system. This study clarifies the spatial and temporal distribution of the Pasaman earthquake sequence and forecasts the earthquake ...

Determination of optimum combination of voxel size and b-value for brain diffusion tensor imaging [PDF]

open access: yes, 2017
Optimum combination of voxel size resolution and b-value for whole brain imaging has been determined. Data images were acquired using a 1.5T magnetic resonance imaging (MRI) system (GE Signa HDxt).

ANALISIS PARAMETER a-VALUE DAN b-VALUE SEBAGAI MITIGASI BENCANA GEMPA BUMI DI NUSA TENGGARA TIMUR

open access: yesJambura Physics Journal, 2022
Research on seismicity parameters in the East Nusa Tenggara region can use the a-value and b-value parameters as the main earthquake precursors. The two parameters are seismic activity level and relief level.

Spatial variation of the aftershock activity across the Kachchh Rift Basin and its seismotectonic implications [PDF]

open access: yes, 2012
We analyzed 3365 relocated aftershocks with magnitude of completeness (Mc) ≥1.7 that occurred in the Kachchh Rift Basin (KRB) between August 2006 and December 2010.

INVESTIGATION OF b-VALUE VARIATIONS IN THE AFRICAN AND PARTS OF EURASIAN PLATES [PDF]

open access: yesScience of Tsunami Hazards, 2017
Numerous earthquakes have occurred along the collision zones of the African and parts of Eurasian plates. Some of these earthquakes along these zones have generated tsunamis.
