Observation of local tectonic movements by a quartz-tube extensometer in the Sopronbánfalva Geodynamic Observatory, in Hungary–Validation of extensometric data by tidal analysis and simultaneous radon concentration measurements [PDF]

open access: yes, 2012
In 1990 a quartz tube extensometer was installed in the Sopronbánfalva Geodynamic Observatory (SGO) of the Geodetic and Geophysical Research Institute of the Hungarian Academy of Sciences. On the basis of the 20 year data series, an average strain rate

Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Geology Matters for Antarctic Geothermal Heat

open access: yesGeophysical Research Letters
Geothermal heat plays a vital role in Antarctic ice sheet stability. The continental geothermal heat flow distribution depends on lithospheric composition and ongoing tectonism. Heat‐producing elements are unevenly enriched in the crust over deep time by

Integrated numerical simulation and source‐sink matching methodology for Basin‐Wide CO2 storage assessment in depleted reservoirs: A Cambay Basin case study

open access: yesDeep Underground Science and Engineering, EarlyView.
This study presents an integrated workflow to evaluate secure and large‐scale CO2 storage in depleted oil reservoirs of the Cambay Basin, India. Industrial CO2 sources are systematically matched with mature oil fields using a quantitative source–sink framework to minimize transport distance and cost.

Determination of Site amplification in the Campania-Lucania Region (southern Italy) by comparison of different Site-Response Estimation Techniques [PDF]

open access: yes, 2008
We have applied a non-linear inversion technique to estimate both the earthquake source parameters and site response from a set of microearthquake records acquired by a dense seismic network, in order to provide a simple uniform site classification for ...
