Seismic Soundoff: The sound of seismic
The Leading Edge, 2023Paolo 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.

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,

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 ...

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
2023With 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 ...

Seismic Design Requirements for Regions of Moderate Seismicity
Earthquake Spectra, 2000The need for earthquake‐resistant construction in areas of low‐to‐moderate seismicity has been recognized through the adoption of code requirements in the United States and other countries only in the past quarter century. This is largely a result of improved assessment of seismic hazard and examples of recent moderate earthquakes in regions of both ...

Origin of Seismicity in Italy as a Clue for Seismic Hazard
2023Italian seismicity is generated by the ongoing subduction of the European lithosphere beneath the Alps, and the Adriatic lithosphere beneath the Apennines. The two belts are extremely different due to their opposite polarity relative to the inferred underlying ‘eastward’ mantle flow.

Seismic waves and seismic barriers
Acoustical Physics, 2011The basic idea of seismic barrier is to protect an area occupied by a building or a group of buildings from seismic waves. Depending on nature of seismic waves that are most probable in a specific region, different kinds of seismic barriers are suggested.
