Scientists investigating the coupling between the lithosphere, atmosphere, and ionosphere (LAI) require multiple instruments installed on and near the Earth’s surface and aboard satellites orbiting the Earth. However, challenges always occur owing to a lack of observation data from other monitoring instruments and/or the distance between distinct instruments. A novel system for monitoring vibratio...... hiện toàn bộ
Coseismic Damage at an Archaeological Site in Sicily, Italy: Evidence of Roman Age Earthquake Surface FaultingGeophysical surveys - Tập 39 - Trang 1263-1284 - 2018

Archaeoseismology can provide a useful chronological tool for constraining earthquakes and documenting significant evidence that would otherwise be lost. In this paper, we report a case of surface faulting on ancient man-made structures belonging to the archaeological site of Santa Venera al Pozzo situated along the eastern flank of Mt. Etna volcano in eastern Sicily (southern Italy), which is aff...... hiện toàn bộ
The significance of surface jointsGeophysical surveys - Tập 7 - Trang 259-271 - 1985
Adrian E. Scheidegger
This brief review demonstrates the significance, on a global scale, of joints as shearing surfaces in the neotectonic stress field. Thus, the principal directions of the neotectonic stress field can be determined by a statistical treatment of joint orientation data. These principal stress directions agree with those postulated from plate tectonic theory in every case, on five continents.
A comparison of satellite systems for gravity field measurementsGeophysical surveys - Tập 3 - Trang 207-223 - 1978
P. Argentiero, B. Lowrey
A detailed and accurate Earth gravity field model is important both to geophysical progress and to the precise tracking necessary for interpretation of geophysical experiments. Various satellite techniques which may be used to determine the Earth's gravity field are compared and their ability to recover the long wavelength and short wavelength features of the field are described. A high-low config...... hiện toàn bộ
Assessing the Current Evolution of the Greenland Ice Sheet by Means of Satellite and Ground-Based ObservationsGeophysical surveys - Tập 35 - Trang 1459-1480 - 2014
A. Groh, H. Ewert, M. Fritsche, A. Rülke, R. Rosenau, M. Scheinert, R. Dietrich
The present study utilises different satellite and ground-based geodetic observations in order to assess the current evolution of the Greenland Ice Sheet (GIS). Satellite gravimetry data acquired by the Gravity Recovery and Climate Experiment are used to derive ice-mass changes for the period from 2003 to 2012. The inferred time series are investigated regarding long-term, seasonal and interannual...... hiện toàn bộ
On the Use of VLF Narrowband Measurements to Study the Lower Ionosphere and the Mesosphere–Lower ThermosphereGeophysical surveys - Tập 38 - Trang 407-441 - 2016
Israel Silber, Colin Price
The ionospheric D-region (~60 km up to ~95 km) and the corresponding neutral atmosphere, often referred to as the mesosphere–lower thermosphere (MLT), are challenging and costly to probe in situ. Therefore, remote sensing techniques have been developed over the years. One of these is based on very low frequency (VLF, 3–30 kHz) electromagnetic waves generated by various natural and man-made sources...... hiện toàn bộ
