Measuring Solar Abundances with Seismology [PDF]
arXiv, 2008 The revision of the photospheric abundances proferred by Asplund et al has rendered opacity theory inconsistent with the seismologically determined opacity through the Sun. This highlights the need for a direct seismological measurement of solar abundances.

Temporal variation of gravity-field in North China before and after the 2011 Japan Mw9.0 earthquake
Geodesy and Geodynamics, 2011 By using absolute and relative-gravity data recorded by the gravity network in North China, we obtained some large-scale and high-spatial-resolution images of gravity variation in this area for the first time. By analyzing these images, we found that the

A study of seismology as a dynamic, distributed area of scientific research [PDF]
Scientometrics 58(1) (2003) 91-114, 2009 Seismology has several features that suggest it is a highly internationalized field: the subject matter is global, the tools used to analyse seismic waves are dependent upon information technologies, and governments are interested in funding cooperative research.

Seismological Understanding of Accelerogram Amplitude Scaling for Engineers with Implications to Seismic Risk Analysis [PDF]
arXiv, 2023 Due to the paucity of strong recorded accelerograms, earthquake engineering analysis relies on accelerogram amplitude scaling for structural damage/collapse assessment and target spectrum matching. This paper investigates seismological characteristics of scaled accelerograms so as to inform future ground motion selection and seismic risk assessment ...

Chromospheric Seismology [PDF]
Symposium - International Astronomical Union, 1988 The aim of the present study is to examine whether seismologic diagnostic techniques may be used to improve the models of the solar chromosphere. We are mainly concerned by oscillations observed in the cores of strong lines such as the resonance lines of Ca II or Mg II. It is intuitive, and confirmed by numerical simulations (Gouttebroze and Leibacher,

Influence of crustal layering and thickness on co-seismic effects of Wenchuan earthquake
Geodesy and Geodynamics, 2011 Using the PSGRN/PSCMP software and the fault model offered by USGS and on the basis of finite rectangular dislocation theory and the local layered wave velocity structures of the crust-upper-mantle, the influences of crustal layering and thickness on co ...

Bayesian Coronal Seismology [PDF]
, 2017 In contrast to the situation in a laboratory, the study of the solar atmosphere has to be pursued without direct access to the physical conditions of interest. Information is therefore incomplete and uncertain and inference methods need to be employed to diagnose the physical conditions and processes.

Application of virtual seismology to DAS data in Groningen [PDF]
arXiv, 2023 In this report we investigate whether and under what conditions virtual seismology via the acoustic Marchenko method can be applied to DAS data from a survey in the province of Groningen, The Netherlands. Virtual seismology allows to retrieve the band-limited Green's function between a virtual source at an arbitrary focal point in the subsurface, while
