An Evaluation of Earthquake Hazard Parameters in and around Ağrı, Eastern Anatolia, Turkey

The earthquake hazard parameters of a and b of Gutenberg-Richter relationships, return periods, expected maximum magnitudes in the next 100 years and probabilities for the earthquakes for certain magnitude values are computed using the earthquakes occurred between 1900 and 2014 years in and around Ağrı.

Multi-fault earthquakes with kinematic and geometric rupture complexity: how common?

We examine 257 finite-fault rupture models for 135 moment magnitude (Mw) 4.1 to 8.1 continental earthquakes to estimate how many source faults ruptured in each earthquake.

The 𝑀𝑤 6.3 Shonbeh (Bushehr) mainshock, and its aftershock sequence: Tectonic implications and seismicity triggering

In this study, the statistics properties of the aftershock sequence and coulomb stress changes due to the mainshock of the 𝑀𝑤= 6.3, 9 April 2013 Shonbeh earthquake have been studied.

Regional Variations of the upper Bound Magnitude of Gill Distribution in the Iranian Plateau

The Iranian Plateau does not appear to be a single crustal block, but an assemblage of zones comprising the Alborz–Azerbaijan, Zagros, Ko-peh–Dagh, Makran, and Central and East Iran.

Stress Interactions in Intraplate Earthquakes

Australia is a seismically active continent with an intraplate compressive stress field primarily driven by far-field plate boundary interactions. Major (magnitude ≥ 5) surface-rupturing earthquakes are primarily sourced from reverse faults.

The Effect of Evaporation on Strength and the Stability of Thickened Tailings Beach Slopes

At the time a layer of tailings slurry comes to rest on the surface of a tailings beach and settles, it has very low shear strength. Before additional layers of tailings are placed over this layer, the strength must increase, or the driving forces of the accumulated tailings will exceed the shear strength, and mass instability will result.

Strength and liquefaction assessment of tailings

Historically, in situ testing of tailings has been primarily based on drilling techniques with the recovery of tube samples, coupled with standard penetration test (SPT), shear vane testing and laboratory test work used to assess the tailings properties.

Numerical Modelling of Seismic Liquefaction for Bobadil Tailings Dam

One of the causes of tailings dam failure has been seismically induced liquefaction during earthquakes. Liquefaction, if mobilised, significantly reduces the stiffness and strength of affected soils in the embankment dam or its foundation and may lead to large deformations and dam failure.

Ultra paste and central thickened discharge: a paradigm shift in tailings management

Tailings management remains a top priority for the mining industry, driven by the pursuit of safety, environmental sustainability and operational efficiency. The accumulation and subsequent loss of water in tailings storage facilities (TSFs) poses a significant challenge, leading to the growing popularity of schemes that reduce water content in tailings.
