Chilean Patagonia is confronted with several geohazards due to its tectonic setting, i.e., the presence of a subduction zone and numerous fault zones (e.g. the Liquiñe-Ofqui Fault Zone). This region has therefore been the subject of numerous paleoseismological studies. However, this study reveals that the seismic hazard is not limited to these large tectonic structures by identifying past fault activity near Coyhaique in the Aysén Region. Mass wasting deposits in Lago Pollux, a lake located ca. 15 km SW of this region’s capital, were identified through analysis of reflection-seismic data and was linked to a simultaneous event recorded in nearby Lago Castor. Furthermore, a coeval ~50 year-long catchment response was identified in Aysén Fjord based on the multiproxy analysis of a portion of a sediment core. Assuming that this widely recognized event was triggered by an earthquake, ground-motion modelling was applied to derive the most likely magnitude and source fault. The model showed that an earthquake rupture along a local fault, in the vicinity of Lago Pollux and Lago Castor, with a magnitude of 5.6–6.8, is the most likely scenario.

The social impact of the outbreak and spread of the COVID–19 pandemic has shown that we’re not facing a mere infectious disease, but a neoliberal syndemic. This syndemic have stressed all the inequalities, oppressions and conflicts that were at the base of the neoliberal system of governance, contradictions that have reached a global dimension since the Great Recession (2008). In this article we will analyze the consequences of the neoliberal virus in different spheres (macro and micro) from a critical and materialistic perspective: from the management of the crisis by the States to the subjective transformations the syndemic has provoked in the population. Focusing in the Spanish case, we will go over the main reactions, narratives and struggles that have faced the Covid crisis into what we understand as a new and more authoritarian phase of neoliberal capitalism. A phase that will need a radical articulation of social struggles to subvert a horizon that threatens with new oppressions. &nbsp, El impacto social del brote y propagación de la pandemia del COVID-19 nos ha mostrado que no estamos ante una mera enfermedad infecciosa, sino ante una sindemia neoliberal. Esta sindemia ha acentuado todas las desigualdades, opresiones y conflictos que estaban en la base del sistema de gobernanza neoliberal, contradicciones que han alcanzado una dimensión global desde la Gran Recesión (2008). En este artículo analizaremos las consecuencias del virus neoliberal en diferentes ámbitos (macro y micro) desde una perspectiva crítica y materialista: desde la gestión de la crisis por parte de los Estados hasta las transformaciones subjetivas que la sindemia ha provocado en la población. Centrándonos en el caso español, repasaremos algunas de las principales reacciones, narrativas y luchas que se han enfrentado la crisis del COVID en lo que entendemos como una nueva fase más autoritaria del capitalismo neoliberal. Una etapa que precisará una articulación radical de las luchas sociales para subvertir un horizonte que amenaza con nuevas opresiones.

Current archaeological paradigm proposes that the first peopling of the Americas does not exceed the Last Glacial Maximum period. In this context, the acceptance of the anthropogenic character of the earliest stone artefacts generally rests on the presence of projectile points considered no more as typocentric but as typognomonic, since it allows, by itself, to certify the human character of the other associated artefacts. In other words, without this presence, nothing is certain. Archaeological research at Piauí (Brazil) attests to a Pleistocene human presence between 41 and 14 cal kyr BP, without any record of lithic projectile points. Here, we report the discovery and interpretation of an unusual stone artefact in the Vale da Pedra Furada site, in a context dating back to 24 cal kyr BP. The knapping stigmata and macroscopic use-wear traces reveal a conception centred on the configuration of double bevels and the production in the same specimen of at least two successive artefacts with probably different functions. This piece unambiguously presents an anthropic character and reveals a technical novelty during the Pleistocene occupation of South America.

In this article we wonder about the effects of May 68 upon the history of philosophy. To address this issue, we reconstruct the philosophical framework and the academic field of the previous years of the revolt, pointing at how inside the existing philosophical styles important changes were being prepared – maninly in the relations between philosophy and sciences–. Departing from Pierre Macherey’s trajectory, we describe the features of the philosophical space of May 68 and its changes –amplification of publics, hybridization of philosophy with other knowledges, collective intellectual enterprises, militant affiliation of discourses–, showing how new models of philosophy are stabilized already in the Post 68 years. At this point, we approach the philosophical practice of Michel Foucault and Louis Althusser, exploring their innovations when it comes to understand philosophy. Finally, we trace a dialogue between the philosophy conceptions’ of Althusser and Macherey; in its tensions the possibilities of a new philosophical canon and a new practice of philosophy are expressed., En este artículo nos interrogamos sobre los efectos de Mayo del 68 en la historia de la filosofía. Para abordar esta cuestión elaboramos una reconstrucción del marco filosófico y el campo académico en los compases previos a la revuelta, señalando cómo dentro de los estilos filosóficos existentes se preparaban importantes mutaciones –fundamentalmente en las relaciones entre la filosofía y las ciencias–. A partir de la trayectoria de Pierre Macherey, mostramos las características del espacio filosófico del Mayo del 68 y sus cambios –ampliación de públicos, hibridación de la filosofía con otros saberes, empresas intelectuales colectivas, filiación militante de los discursos –, mostrando cómo se estabilizan nuevos modelos de filosofía ya en el Post 68. En este punto,  abordamos la práctica filosófica de Michel Foucault y Louis Althusser, explorando sus innovaciones a la hora de entender la filosofía. Finalmente, trazamos un diálogo entre las concepciones de la filosofía de Althusser y Macherey; en sus tensiones se expresan las posibilidades de un nuevo canon filosófico y una nueva práctica de la filosofía.
