Inherited crustal deformation along the East Gondwana margin revealed by seismic anisotropy tomography
Acknowledgments We thank Mallory Young for providing phase velocity measurements in mainland Australia and Tasmania. Robert Musgrave is thanked for making available his tilt-filtered magnetic intensity map. In the short term, data may be made available by contacting the authors (S.P. or N.R.). A new database of passive seismic data recorded in Australia is planned as part of a national geophysics data facility for easy access download. Details on the status of this database may be obtained from the authors (S.P., N.R., or A.M.R.). There are no restrictions on access for noncommercial use. Commercial users should seek written permission from the authors (S.P. or N.R.).

Uma breve análise sobre phishing
The number of phishing attacks reached in 2021 the highest number of all time until then, being the triple since 2020. This event demonstrates that as phishing techniques are shaped considering the context of their target since its emergence in 1995, these attacks end up adapting over time and, thus, this problem persists in society for more than 25 years and continues to increase its number of victims. With that, this work presents a study about what is phishing, its concepts, its types and the problems caused in society.O número de ataques phishing atingiu em 2021 o maior número de todos os tempos até então, sendo o triplo desde 2020. Tal evento demonstra que, desde seu surgimento em 1995, como as técnicas de phishing são moldadas considerando o contexto de seu alvo, esses ataques acabam se adaptando com o tempo e, dessa forma, tal problema persiste na sociedade há mais de 25 anos e continua aumentando seu número de vítimas. Com isso, este trabalho apresenta um estudo sobre o que é phishing, seus conceitos, seus tipos e os problemas causados na sociedade
Mid-mantle deformation inferred from seismic anisotropy
With time, convective processes in the Earth's mantle will tend to align crystals, grains and inclusions. This mantle fabric is detectable seismologically, as it produces an anisotropy in material properties—in particular, a directional dependence in seismic-wave velocity. This alignment is enhanced at the boundaries of the mantle where there are rapid changes in the direction and magnitude of mantle flow, and therefore most observations of anisotropy are confined to the uppermost mantle or lithosphere and the lowermost-mantle analogue of the lithosphere, the D" region. Here we present evidence from shear-wave splitting measurements for mid-mantle anisotropy in the vicinity of the 660-km discontinuity, the boundary between the upper and lower mantle. Deep-focus earthquakes in the Tonga–Kermadec and New Hebrides subduction zones recorded at Australian seismograph stations record some of the largest values of shear-wave splitting hitherto reported. The results suggest that, at least locally, there may exist a mid-mantle boundary layer, which could indicate the impediment of flow between the upper and lower mantle in this region
