Preliminary results of South American infrasound monitoring

Autor: Lucas Vieira Barros, Brandow Neri

Infrasound monitoring is one of the four technologies used by the International Monitoring System to verify compliance with the CTBT. Atmospheric and shallow underground nuclear explosions can generate infrasound waves that can be detected by the inf

Rupture dynamics and fault mechanics of intraplate earthquakes in Brazil

Autor: Lucas Vieira Barros, Juraci Carvalho, Alice-Agnes Gabriel, George Sand França, Elizabeth H. Madden

Mitigating intraplate earthquakes is necessary, as local populations are at risk both directly from strong shaking and indirectly from the threat to public infrastructure such as dams. However, the infrequency of these events and insufficient knowled

Estimating Seismometer Orientations from Teleseismic P-Wave Particle Motion Analysis

Autor: Diogo Farrapo Albuquerque, Marcelo Peres Rocha, Marco Ianniruberto, George Sand França, Reinhardt A. Fuck, Matheus Figueredo de Paulo, Marcos Breno Aguiar, Marcelo Bianchi, Marcelo Assumpção, Lucas Vieira Barros

Publikováno v: Brazilian Journal of Geophysics. 39:197

Three-component seismometers are essential for seismological methods that demand rotational transformations on the horizontal components. In order to verify the orientation of seismometers installed on Pantanal, Chaco and Paraná Structural Studies N

Focal mechanisms and moment magnitudes of micro-earthquakes in central Brazil by waveform inversion with quality assessment and inference of the local stress field

Autor: Lucas Vieira Barros, Jiří Zahradník, Juraci Carvalho

Publikováno v: Journal of South American Earth Sciences. 71:333-343

This paper documents an investigation on the use of full waveform inversion to retrieve focal mechanisms of 11 micro-earthquakes (Mw 0.8 to 1.4). The events represent aftershocks of a 5.0 mb earthquake that occurred on October 8, 2010 close to the ci

Earthquake relocation, focal mechanism and stress field determination in central Brazil

Autor: Mônica Giannoccaro Von Huelsen, Juraci Carvalho, Lucas Vieira Barros, Jiří Zahradník, Vinicius Martins Ferreira

Publikováno v: Journal of South American Earth Sciences. 97:102411

In this work, we perform a seismological investigation in the central Brazil region for focal mechanisms and stress. This large area (910.000 km2) is surrounded by several geological provinces: Eastern Amazon craton; southwestern Parnaiba basin; west
