Transform fault earthquakes in the North Atlantic: Source mechanisms and depth of faulting [PDF]

open access: yes, 1988
The centroid depths and source mechanisms of 12 large earthquakes on transform faults of the northern Mid-Atlantic Ridge were determined from an inversion of long-period body waveforms.

Carbon Dots: An Emerging Frontier for Green and Sustainable Civil Engineering Materials

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Traditional civil engineering materials (CE materials) are usually involved with high‐energy consumption during manufacturing, significant maintenance costs, and substantial environmental impacts throughout their life cycles. The progress of nanotechnology is catalyzing a green and sustainable transformation within the field.

Possible precursor to the March 11, 2011, Japan earthquake: ionospheric perturbations as seen by subionospheric very low frequency/low frequency propagation

open access: yesAnnals of Geophysics, 2012
<p>This study reports on a possible very low frequency/low frequency (VLF/LF) subionospheric precursor to a recent earthquake in Japan. As the epicenter of this large Japanese earthquake on March 11, 2011, was located just on the great-circle path ...

The Effect of Catalogue Lead Time on Medium-Term Earthquake Forecasting with Application to New Zealand Data

open access: yesEntropy, 2020
‘Every Earthquake a Precursor According to Scale’ (EEPAS) is a catalogue-based model to forecast earthquakes within the coming months, years and decades, depending on magnitude.

Scale free networks of earthquakes and aftershocks

open access: yes, 2003
We propose a new metric to quantify the correlation between any two earthquakes. The metric consists of a product involving the time interval and spatial distance between two events, as well as the magnitude of the first one.

Configurational Energy as a Microstructural Descriptor of Failure Precursors in 2D Frictional Granular Materials

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Localized deformation in dense granular materials, often culminating in the formation of shear bands, is a key failure mechanism in geotechnical and material systems. However, predicting the onset of such localization remains a fundamental challenge due to the system's inherent inelasticity and microstructural complexity.

Оценка эффективности прогноза землетрясений в Камчатском регионе по комплексу ионосферных аномалий

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2022
Существует прямая зависимость между солнечной активностью и процессами в магнитосфере, ионосфере и литосфере Земли. Однако существует и обратная связь, определяющая влияние литосферных процессов сейсмоактивных регионов на физические процессы, протекающие
