    Can Earth's rotation and tidal despinning drive plate tectonics? (2010)
    Elsevier
    Details
    Publication Date: 2017-04-04
    Description: We re-evaluate the possibility that Earth's rotation contributes to plate tectonics on the basis of the following observations: 1) plates move along a westerly polarized flow that forms an angle relative to the equator close to the revolution plane of the Moon; 2) plate boundaries are asymmetric, being their geographic polarity the first order controlling parameter; unlike recent analysis, the slab dip is confirmed to be steeper along W-directed subduction zones; 3) the global seismicity depends on latitude and correlates with the decadal oscillations of the excess length of day (LOD); 4) the Earth's deceleration supplies energy to plate tectonics comparable to the computed budget dissipated by the deformation processes; 5) the Gutenberg–Richter law supports that the whole lithosphere is a self-organized system in critical state, i.e., a force is acting contemporaneously on all the plates and distributes the energy over the whole lithospheric shell, a condition that can be satisfied by a force acting at the astronomical scale. Assuming an ultra-low viscosity layer in the upper asthenosphere, the horizontal component of the tidal oscillation and torque would be able to slowly shift the lithosphere relative to the mantle.

    Global pattern of earthquakes and seismic energy distributions: Insights for the mechanisms of plate tectonics (2012)
    Elsevier Science Limited
    Details
    Publication Date: 2017-04-03
    Description: In this paper, we analyse the distributions of number of events (N) and seismic energy (E) on the Earth's surface and along its radius as obtained from the global declustered catalogue of large independent events (M≥7.0), dissipating about 95% of the Earth's elastic budget. The latitude distribution of the seismic event density is almost symmetric with respect to the equator and the seismic energy flux distribution is bimodal; both have their medians near the equator so that they are equally distributed in the two hemispheres. This symmetry with respect to the equator suggests that the Earth's rotational dynamics contributes to modulate the long-term tectonic processes. The distributions of number and energy of earthquakes versus depth are not uniform aswell: 76% of the total earthquakes dissipates about 60% of the total energy in the first ~50 km; only 6% of events dissipates about 20% of the total amount of energy in a narrow depth interval, at the lower boundary of the upper mantle (550–680 km). Therefore, only the remaining 20% of energy is released along most of the depth extent of subduction zones (50–550 km). Since the energetic release along slabs is a minor fraction of the total seismic budget, the role of the slab pull appears as ancillary, if any, in driving plate tectonics. Moreover the concentration of seismic release in the not yet subducted lithosphere suggests that the force moving the plates acts on the uppermost lithosphere and contemporaneously all over the Earth's outer shell, again supporting a rotational/tidal modulation.

    A highly sensitive quartz-crystal microbalance for sputtering investigations in slow ion–surface collisions (1999)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 70 (1999), S. 3696-3700 
    Details
    ISSN: 1089-7623

    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A quartz-crystal microbalance technique for measuring total sputter yields in ion–surface collisions is described. The electronic circuit to drive the quartz crystal ensures low noise and high frequency stability. By measuring total sputter yields for impact of singly charged ions on LiF target films a sensitivity limit of 0.5% of a monolayer per minute could be achieved. © 1999 American Institute of Physics.

    Laboratory calibration of Lacoste–Romberg type gravimeters by using a heavy cylindrical ring (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 120 (1995), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: A calibration device developed for Lacoste-Romberg (LCR) gravimeters in the Geodynamical observatory of the Eötvös Loránd Geophysical Institute of Hungary is described. The equipment generates gravity variations of about 112 μGal with the use of a suspended cylindrical ring of mass 3200 kg.A ring with an inner diameter slightly bigger than the width of the instrument to be calibrated is raised and lowered over the gravimeter installed on a column. The advantages of this solution with respect to others are: the gravimeter remains stationary during the calibration process, the gravity variations generated by the ring have smooth extrema, they are larger than variations caused by bodies with other geometry, the experiment is symmetrical with respect to the gravimeter and no ground loading by the ring occurs. The device allows a calibration accuracy for LCR instruments of the order of 0.1 per cent to be attained. This is a considerable improvement for absolute calibrations in a very narrow range, especially in the context of tidal measurements.To reach such an error level the instrumental drift, tidal variation, the microseisms and air pressure must be removed most accurately from the measured data. The position of the ring in space and time is measured with an accuracy of 0.1 mm and ***1 s. The tilt of the frame and of the instruments must be recorded and excluded from the experimental results. Calibration results obtained with the device are compared to the calibration values obtained at broad and medium ranges along two calibration lines with different ranges.
