Rapid earthquake magnitude classification via P-wave strains from borehole strainmeters and Distributed Acoustic Sensing [PDF]

Nature Communications
Distributed Acoustic Sensing (DAS) offers a promising approach for earthquake early warning (EEW) in settings where seismic networks are costly to maintain.

Previously hidden landslide processes revealed using distributed acoustic sensing with nanostrain-rate sensitivity [PDF]

Nature Communications
Landslides sometimes creep for decades before undergoing runaway acceleration and catastrophic failure. Observing and monitoring the evolution of strain in time and space is crucial to understand landslide processes, including the transition from slow to

Non-Invasive Methodological Approach to Detect and Characterize High-Risk Sinkholes in Urban Cover Evaporite Karst: Integrated Reflection Seismics, PS-InSAR, Leveling, 3D-GPR and Ancillary Data. A NE Italian Case Study

Remote Sensing, 2020
Sinkholes linked to cover evaporite karst in urban environments still represent a challenge in terms of their clear identification and mapping considering the rehash and man-made structures.

Exploring the Significance of Digitalized Logs and Seismics through Structural Modelling and Petrophysical Analyses: Case study: Neogene-Paleogene reservoirs of the Rio Del Rey Basin, Gulf of Guinea. Cameroon

Results in earth sciences
The advent of geophysics into the world of hydrocarbon exploration has been proven to date very far back in time demonstrated by information from well logs and seismics.

Application of first arrival seismic tomography in a glaciated basin: implications for paleo-ice stream development

Journal of Glaciology, 2023
Ice streams are sites of ice-sheet drainage and together with other processes, such as calving, have an impact on deglaciation rates and ice-sheet mass balance.

Glacial hydraulic tremor on Rhonegletscher, Switzerland

Journal of Glaciology, 2023
Glacial hydraulic tremor (GHT) can be monitored to observe changes in location and distribution of water flow beneath glacial ice, allowing the spatiotemporal evolution of subglacial hydrology to be studied continuously and remotely.

Composite model of seismic monitoring data analysis during mining operations on the example of the Kukisvumchorrskoye deposit of AO Apatit

Записки Горного института, 2023
Geomechanical monitoring of the rock mass state is an actively developing branch of geomechanics, in which it is impossible to distinguish a single methodology and approaches for solving problems, collecting and analyzing data when developing seismic ...

A synthetic study of acoustic full waveform inversion to improve seismic modelling of firn

Annals of Glaciology, 2022
The density structure of firn has implications for hydrological and climate modelling and for ice shelf stability. The firn structure can be evaluated from depth models of seismic velocity, widely obtained with Herglotz-Wiechert inversion (HWI), an ...

Fractal Seismicity and Seismic Risk [PDF]

Izvestiya, Physics of the Solid Earth, 2020
Recently, attempts have been made to take into account the fractal properties of seismicity when mapping the long-term rate of earthquakes. The paper touches upon the theoretical aspects of fractality and provides a critical analysis of its applications to the problems of seismic ...
