Combined use of refraction seismic, MASW, and ambient noise array measurements to determine the near-surface velocity structure in the Selinunte Archaeological Park, SW Sicily
(
- Journal of Seismology
, 2020-02-29)
Seismic refraction, multichannel analysis of surface waves (MASW) and ambient noise array measurements using the wireless array analysis (WARAN) system were applied to acquire near-surface profiles of seismic velocities ...
How Different Analysis and Interpolation Methods Affect the Accuracy of Ice Surface Elevation Changes Inferred from Satellite Altimetry
(
- Mathematical Geosciences
, 2020-01-28)
Satellite altimetry has been widely used to determine surface elevation changes in polar ice sheets. The original height measurements are irregularly distributed in space and time. Gridded surface elevation changes are ...
A robust potential-based contact force solution approach for discontinuous deformation analysis of irregular convex polygonal block/particle systems
(
- Acta Geotechnica
, 2020-07-27)
Contact interaction of two bodies can be modeled using the penalty function approach while its accuracy and robustness are directly associated with the geometry of contact bodies. Particularly, in the research fields of ...
Stress-based, statistical modeling of the induced seismicity at the Groningen gas field, The Netherlands
(
- Environmental Earth Sciences
, 2020-05-22)
Groningen is the largest onshore gas field under production in Europe. The pressure depletion of the gas field started in 1963. In 1991, the first induced micro-earthquakes have been located at reservoir level with increasing ...
The 1994 Piedmont flood: an archetype of extreme precipitation events in Northern Italy
(
- Bulletin of Atmospheric Science and Technology
, 2020-09-01)
Extreme precipitation events (EPEs) are meteorological phenomena of major concern for the densely populated regions of northern and central Italy. Although statistically rare, they tend to be recurrent in autumn and share ...
Gravity Field Modeling Using Tesseroids with Variable Density in the Vertical Direction
(
- Surveys in Geophysics
, 2020-03-26)
We present an accurate method for the calculation of gravitational potential (GP), vector (GV), and gradient tensor (GGT) of a tesseroid, considering a density model in the form of a polynomial up to cubic order along the ...
Accuracy of fully coupled and sequential approaches for modeling hydro- and geomechanical processes
(
- Computational Geosciences
, 2020-07-12)
Subsurface flow and geomechanics are often modeled with sequential approaches. This can be computationally beneficial compared with fully coupled schemes, while it requires usually compromises in numerical accuracy, at ...
Single-station seismic microzonation using 6C measurements
(
- Journal of Seismology
, 2020-08-05)
Microzonation is one of the essential tools in seismology to mitigate earthquake damage by estimating the near-surface velocity structure and developing land usage plans and intelligent building design. The number of ...
Cultural heritage and earthquakes: bridging the gap between geophysics, archaeoseismology and engineering
(
- Journal of Seismology
, 2020-06-18)
This is the editoral of a special issue that is focused on the multidisciplinary approach to cultural heritage preservation, with
special care to the impact of earthquakes and their
associated effects. For that, we have ...
Forward Gravity Modelling to Augment High-Resolution Combined Gravity Field Models
(
- Surveys in Geophysics
, 2020-04-17)
During the last few years, the determination of high-resolution global gravity field has gained momentum due to high-accuracy satellite-derived observations and development of forward gravity modelling. Forward modelling ...
