    Extreme wave deposits on the Pacific coast of Mexico: Tsunamis or storms? - A multi-proxy approach
    (ELSEVIER, 2012) Ramirez Herrera, Maria Teresa; Lagos, Marcelo; Hutchinson, Ian; Kostoglodov, Vladimir; Luisa Machain, Maria; Caballero, Margarita; Goguitchaichvili, Avto; Aguilar, Bertha; Chague Goff, Catherine; Goff, James; Ruiz Fernandez, Ana Carolina; Ortiz, Modesto; Nava, Hector; Bautista, Francisco; Lopez, Gloria I.; Quintana, Patricia
    Historical and instrumental data show that the Pacific coast of Mexico has been exposed to destructive tsunamis over at least the past 500 years. This coast is also affected by hurricanes generated in the eastern Pacific. The great 1985 Mexico earthquake and its aftershock generated tsunamis that affected the Ixtapa-Zihuatanejo and Michoacan coast. The purpose of our study was two-fold - a) to determine whether storm and tsunami deposits could be distinguished, and b) whether tsunami deposits from historical events are preserved in the tropical environments of the Ixtapa-Zihuatanejo coast.

    Territorial planning on the coast of central Chile: incorporation of environmental fragility and risk criteria
    (PONTIFICA UNIV CATOLICA CHILE, INST GEOGRAFIA, 2010) Andrade, Belisario; Arenas, Federico; Lagos, Marcelo
    Analysis of the state of territorial planning tools of the coastal zone of the Maule Region (Central Chile) are made and compared with spatial units of a detailed scale of environmental fragility and tsunami risk. Notice is made of the precariousness and scarce incorporation of environmental considerations of these tools. In this sense, a zonification that allows for the incorporation of environmental variables is proposed for the planification tools of the coastal zone.

    Visión histórica de la respuesta a las amenazas naturales en Chile y oportunidades de gestión del riesgo de desastre
    (PONTIFICA UNIV CATOLICA CHILE, INST GEOGRAFIA, 2016) Camus, Pablo; Arenas, Federico; Lagos, Marcelo; Romero, Andres
    The geographical conditions in Chile make it a country that persistently experiences natural hazards, constantly testing the capacity of the Chilean society to pull itself up after every event and to improve the ways in which they occupy their territorial space. The prevalence of zoning that focus almost exclusively on profitability and places little attention on localized risks, has allowed a majority of settlement projects and facilities to be built in areas that face significant risk due to natural hazards. The aim of this work is to present a historical review of the subject, seeking to illustrate previous experiences in order to establish more sustainable forms of building within the Chilean geographical space.

    Young People Are Changing Their Socio-Ecological Reality to Face Climate Change: Contrasting Transformative Youth Commitment with Division and Inertia of Governments
    (MDPI, 2022) Pena-Vega, Alfredo; Cohen, Marianne; Manuel Flores, Luis; Le Treut, Herve; Lagos, Marcelo; Carlos Castilla, Juan; Gaxiola, Aurora; Marquet, Pablo
    This paper contributes to a critical re-reading of the notion of climate services. It does so by problematizing the discontinuity between young people's commitment to climate change, and the lack of a common vision regarding climate policy among governments. In this essay, youth commitment is characterized in terms of participation in the Global Youth Climate Pact (GYCP, 2015-2022). Here, young people share projects from their own high schools and communities and participate in a citizen consultation. Most projects have achieved a good success score, increasing over the years, especially for those carried out in emerging and developing countries. Some of them were presented at the COPs. In contrast, a textual analysis of intended nationally determined contributions (INDC) illustrates divergent understandings of the Paris Agreement and exemplifies the poor results of governmental climate diplomacy. This study establishes the need to closely monitor early warning signs of climate change in conjunction with high schools and school communities. The initiatives of young people are building a civic and planetary awareness for climate change in contrast with governmental division and inertia. In this sense, climate services, directed to young people, could contribute to design a sustainable future. We approach the practices, attitudes, and commitments of young people from the angle of cooperation rather than a moral vision of responsibility. Particularly, we propose a dialogical link between the treatment of climate issues and its effects on the constitution of networks, notably as they relate to practices of action, that is, the way in which distinct groups of young people develop relationships with their environments, organize themselves, and act and transform reality.
