Long-range correlation studies in deep earthquakes global series
Douglas S. R. Ferreira, Jennifer Ribeiro, Paulo S. L. Oliveira +3
In the present paper we have conducted studies on seismological properties using worldwide data of deep earthquakes (depth larger than 70 km), considering events with magnitude $m…
Rayleigh and acoustic gravity waves detection on magnetograms during the Japanese Tsunami, 2011
Virginia Klausner, Esfhan A. Kherani, Marcio T. A. H. Muella +3
The continuous geomagnetic field survey holds an important potential in future prevention of tsunami damages, and also, it could be used in tsunami forecast. In this work, we were…
On the agreement between small-world-like OFC model and real earthquakes
Douglas S. R. Ferreira, Andrés R. R. Papa, Ronaldo Menezes
In this article we implemented simulations of the OFC model for earthquakes for two different topologies: regular and small-world, where in the latter the links are randomly rewire…
Towards Evidence of Long-Range Correlations in Shallow Seismic Activities
Douglas S. R. Ferreira, Jennifer Ribeiro, Andrés R. R. Papa +1
In this work, we introduce a new methodology to construct a network of epicenters that avoids problems found in well-established methodologies when they are applied to global catal…
A Study of Pc4-5 Geomagnetic Pulsations in the Brazilian Sector
David Oliva, Marcela C. Meirelles, Andrés R. R. Papa
This paper presents a study of Pc4-5 geomagnetic pulsations illustrated by those which were observed after the sudden commencement of May 02 of 2010 at 09 : 08 UT at the Brazilian…
Daily Variations of the Geomagnetic Field in the Brazilian zone
David Oliva, Marco A. Espírito Santo, Andrés R. R. Papa
The solar quiet daily variation (Sq) was investigated with respect to the longitudinal and seasonal variations at the Brazilian geomagnetic ground stations of Tatuoca (TTB), Vassou…
