Abstract. The similarity of the vertical displacements shown by case-history extreme-magnitude earthquakes are scrutinised (Chile 1960, Alaska 1964, Sumatra 2004. A common interpretation -an uprising of lithospheric materialcan be found, which is supported by the irregularities of the hypocentres distribution along the Wadati-Benioff zones. In the case of major South American earthquakes, a volcanic eruptions-earthquakes correlation is recognisable.Further support to this interpretation is the displacement of the Earth's instantaneous rotation pole -≈3.0 mas (≈10 cm), observed at ASI of Matera, Italy -the seismic data (USGS) in the two days following the main shock, the geomorphologic data, and the satellite data of uplift/subsidence of the coasts (IGG) make possible a new interpretation of the Great Sumatran earthquake (26 December 2004) based on the second conjugate -nearly vertical -CMT fault plane solution.All this converges toward different causes of seismogenetic processes, strongly supporting a deep origin of disturbances, fluxes of materials leading to more or less sudden movements of masses, and phase changes, which lead to either earthquakes or silent-slow events in Wadati-Benioff zones. A reinterpretation of the geodynamics of the active margins and mountain building is proposed with a heuristic model that does not resort to large-scale subduction, but only to isostatic uplift of deep material intruding between two decoupling plates in a tensional environment. Concomitant phase changes toward less-packed lattice and buoyancy effect caused by the Clapeyron slope can help the extrusion of material over the m.s.l., constituting an orogenic process. The phenomena expected to occur in the model directly and harmoniously contribute to the building up of the surface geophysical and geomorphological features of the orogenic zones.
In the March 2019 issue of the Rendiconti Online of the SGI, a geologist continued his attack on the theory of terrestrial expansion (Sudiro, 2019), this time focusing on the implications that paleomagnetic data, particularly the paleopoles, have as evidence for the expanding Earth concept. An initial more general publication on the subject by the same author appeared in the EGU History of the Earth Sciences journal in 2014 (Sudiro, 2014). The present paper demonstrates the inadequacy of many of the criticisms formulated in the above publications, making it clear that the Expanding Earth is not an outdated idea from the historical-scientific contingencies of the past, but instead a scientific concept that is very much alive and with very interesting future prospects. The evidential value of the paleopole data and catalogues is specifically defended here, together with the TPW and its link to the opening of the Pacific Ocean. The numerous lines of research that have emerged on the basis of EE are briefly described in a non-exhaustive review. The failure to recognise the expansion of celestial bodies as a phenomenon could be a contributing factor to the current state of crisis in Physics and Cosmology.
In August 1991, through the World Data Center A in Boulder, Colo., the first version of the Global Paleomagnetic Database (GPMDB) developed by Lock and McElhinny [1991] was released for general use. Two versions of the GPMDB were developed, the first for the ORACLE Database Management System and the second in ASCII form.
A program that allows remote users to search the “ABASE” version of GPMDB via Internet, selecting data on the basis of geographical coordinates of sampling sites and magnetization ages, was recently presented in Eos [Harbert, 1993].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
