Experiments on Seismic Activity

open access: yes, 2021
A likely discovery of Earth's body-soul synchronicity event is presented and discussed. In theory, detectors of such events could be used as reliable predictors of seismic activity during periods when Earth's soul is evolutionary ahead of the body. Indeed, analysis of performed experiments shows correlation with seismic activity - strong signal was ...

Active Metamaterials with Tunable Shear Nonreciprocity and Nonlinear Dynamics

open access: yesAdvanced Science, EarlyView.
Active gear‐based mechanical metamaterials enable simultaneous control of translational and torsional stiffnesses by 30–100×, break shear reciprocity under positive versus negative loads, broadly tune resonant frequencies, and offer programmable dynamic responses.

Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

Impact of global seismicity on sea level change assessment

open access: yes, 2005
We analyze the effect of seismic activity on sealevel variations, by computing the time-dependent vertical crustal movement and geoid change due to coseismic deformations and postseismic relaxation effects.

Nonvolcanic tremor observed in the Mexican subduction zone [PDF]

open access: yes, 2008
Nonvolcanic tremor (NVT) activity is revealed as episodes of higher spectral amplitude at 1–8 Hz in daily spectrograms from the continuous seismological records in Guerrero, Mexico.

Socioenvironmental implications of Jatropha curcas cultivation for biodiesel supply in postmining communities

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The long‐term viability of Jatropha curcas as a biodiesel feedstock has been widely debated. Many early initiatives failed to deliver consistent economic returns despite promising environmental attributes. This study re‐evaluated J. curcas‐based systems within an integrated environmental–economic framework, focusing on their potential role in ...

Wireless Telemetry: Channel Characterization and Statistical Imputation of Missing Values

open access: yesCommunications, 2015
An implemented communication wireless telemetric system is presented. It has been built to serve as a measuring station at Thermopiles hot springs. The present work analyzes the method applying several models for adjusting and optimizing the functions of

Prediction and verification of earthquakes induced by the Xiluodu hydropower station reservoirKey points

open access: yesEarthquake Science, 2022
Research has been conducted on reservoir-induced earthquakes in China since the Xinfengjiang reservoir-induced earthquakes in the 1960s. Regulations now require the risk of reservoir-induced earthquakes to be evaluated in the pre-research stage of all ...

Extracting information from noise [PDF]

open access: yes, 2010
Seismic waves created by sources such as wind, the ocean and human activity propagate inside the Earth all the time. Such waves are often regarded as ‘noise’ by seismologists, however, they travel through the Earth in exactly the same way as those ...
