Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

open access: yesBoreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

An estimation method for effective stress changes in a reservoir from 4D seismics data

open access: yesGeophysical Prospecting, 2013
Advances in seismics acquisition and processing and the widespread use of 4D seismics have made available reliable production-induced subsurface deformation data in the form of overburden time-shifts.

On the use of a seismic sensor as a seismic source

Geophysics, 2013
ABSTRACT We investigated the use of seismic sensors as small seismic sources. A voltage signal is applied to a geophone that forces the mass within the geophone to move. The movement of the mass generates a seismic wavefield that was recorded with an array of geophones operating in the conventional sense. We observed higher-frequency (

Seismicity, seismotectonics and seismic hazard of Italy

Engineering Geology, 2000
Abstract A first generation of probabilistic seismic hazard maps of the Italian country are presented. They are based on seismogenic zoning deriving from a kinematic model of the structural tectonic units and on an earthquake catalogue with the foreshock and aftershock events filtered out. The following ground motion parameters have been investigated

Seismic Soundoff: The sound of seismic

The Leading Edge, 2023
Paolo Dell'Aversana highlights his recent article in The Leading Edge, “An expanded idea of imaging in geophysics through multimodal data analysis.” The article explores a dual-sensory approach to understanding seismic data. This episode unlocks secret information hiding in seismic data that is waiting to be discovered.

The seismicity of ghana

Bulletin of Earthquake Engineering, 2013
Although West Africa is generally an area of very low seismicity, an exception is a concentration of activity in Southern Ghana, especially near to the capital, Accra, which was heavily damaged by earthquakes in 1862 and 1939. Modern instrumental seismicity is poorly understood due to the limitations of seismic monitoring in the country. In this study,

The Seismic Sun

Symposium - International Astronomical Union, 1997
Helioseismic techniques allow us to probe the interior of the Sun with very high precision and in the process test the physical inputs to stellar models. The picture of the Sun that has been built in this manner may be termed “The Seismic Sun”. After a brief discussion of some of the inversion techniques used in the process, our current view of the ...

Seismic imaging

Geophysics, 2001
Abstract Unmigrated reflection seismic energy recorded at the earth's surface, for example in the form of common-offset records, often provides a remarkably coherent picture of subsurface structure. Coherent as it might be, however, this picture is not correct, suffering from several distorting effects, most notably those of ...

Estimating the seismicity of Venus by scaling Earth’s seismicity

2023
With the selection of multiple missions to Venus by NASA and ESA planned to launch in the coming decade, we will greatly improve our understanding of Venus as a planet. However, the selected missions cannot tell us anything about the seismicity on Venus, which is a crucial observable to constrain the tectonic activity and geodynamic regime of the ...
