Analysis of Time Dynamical Features in Intraplate Versus Interplate Seismicity: The Case Study of Iquique Area (Chile)
(Springer, 2020)
The intraplate and interplate seismic catalogues of Iquique (Chile) area were investigated by using seismological (bvalue of the Gutenberg-Richter law), fractal (Allan Factor and detrended fluctuation analysis) and topological ...
The intraplate Porto dos Gauchos seismic zone in the Amazon craton - Brazil
(ELSEVIER SCIENCE BV, 2009)
The largest earthquake observed in the stable continental interior of the South American plate occurred in Serra do Tombador, Mato Grosso state - Brazil, on January 31,1955 with a magnitude of 6.2 m(b). Since then no other ...
Shallow intraplate seismicity related to the Illapel 2015 Mw 8.4 earthquake: Implications from the seismic source
(Elsevier B.V., 2019)
The September 16, 2015, Mw 8.4 Illapel, Chile earthquake is the first large event occurring in north-central Chile after the 1943 earthquake, filling a known seismic gap in the region. The earthquake took place in a complex ...
Upper crustal earthquake swarms in São Caetano: reactivation of the Pernambuco shear zone and trending branches in intraplate Brazil
(Amsterdam, 2014-04-10)
Seismogenic fault reactivation of continental-scale structures has been observed in a few intraplate areas, but its cause is still amatter of debate. The objective of the present study is to analyze two seismic swarms that ...
Tectonostratigraphic characterization of the adjacent portion to the São Vincente earthquake epicenter in the santos basin
(2015-01-01)
The São Vicente earthquake, which had occurred in the Santos Basin, approximately 200 km from São Vicente city, São Paulo state in 2008, was well detected in the global network, allowing a good determination of their focal ...
Basement depths in the Parecis Basin (Amazon) with receiver functions from small local earthquakes in the Porto dos Gauchos seismic zone
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Receiver functions from small local earthquakes were used to determine sediment thicknesses in Porto dos Gauchos seismic zone (PGSZ), Parecis basin, Amazonian craton, Brazil. The high velocity contrast between basement and ...
Sismicidade e correlação com feições geológicas: o caso do lineamento Pernambuco e seu entorno
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2013-08-16)
This thesis presents and discusses the results of the various seismic areas in the State
of Pernambuco, with the aim of having a vision of regional seismicity and its causes. To the
papers published in journals were added ...
Earthquakes Felt in the Juan Fernandez Islands: Where Are They Coming from?
(Seismological Society of America, 2020)
The Juan Fernandez Islands (JFI) are located in the Pacific Ocean 675 km west of the Chilean coast. This archipelago has historically been affected by large tsunamis. Robinson Crusoe Island (RCI), the main island of the ...
The Sao Vicente earthquake of 2008 April and seismicity in the continental shelf off SE Brazil: further evidence for flexural stresses
(Wiley-Blackwell, 2011-12-01)
The continental margin and shelf of most stable intraplate regions tend to be relatively more seismically active than the continental interior. In the southeast continental margin of Brazil, a seismic zone extends from Rio ...
