CURBE was established in 1997 to create a structure for interdisciplinary collaboration for disaster and risk research and application. Projects link the skills and expertise from distinct disciplines to understand and resolve disaster and risk issues, particularly related to reducing detrimental impacts of disasters. CURBE is based at the Martin Centre within the Department of Architecture at the University of Cambridge. About the research This report is one of a number of outputs from a research project funded by the UK Engineering and Physical Sciences Research Council (EPSRC), entitled Indicators for Measuring, Monitoring and Evaluating Post-Disaster Recovery. The overall aim of the research is to develop indicators of recovery by exploiting the wealth of data now available, including that from satellite imagery, internet-based statistics and advanced field survey techniques. The specific aim of this trip report is to describe the planning process after major disaster with a view to understanding the information needs of planners. Project team The project team has included Michael Ramage, Dr Emily So, Dr Torwong Chenvidyakarn and Daniel Brown, CURBE, University of Cambridge Ltd; Professor Robin Spence, Dr Stephen Platt and Dr Keiko Saito, Cambridge Architectural Research; Dr Beverley Adams and Dr John Bevington, ImageCat. Inc; Dr Ratana Chuenpagdee, University of Newfoundland who led the fieldwork team in Thailand; and Professor Amir Khan, University of Peshawar who led the fieldwork team in Pakistan. The Steering Committee included Professor Arleen Hill, Department of Earth Sciences, University of Memphis, USA; Professor Peter Atkinson, School of Geography, University of Southampton, UK; Professor Ian Davis, Cranfield University, UK; Mr. Doekle Wielinga, World Bank.

In brief, I visited three cities: Concepción, Viña del Mar and Valparaiso, that were subject to earthquake damage and three small coastal settlements, Tumbes, Dichato and Tubul, Region Bio-Bio, that were hit by the subsequent tsunami. I interviewed senior people in the Ministry of Transport and the Ministry of Housing and Urbanism responsible for coordinating national reconstruction, people in Bio-Bio responsible for reconstruction in that region and residents in the coastal settlements. The field trip took place between 10–18 September 2011, 18 months after the event. I spent five days based in Concepción, from where I visited the city centre, San Pedro, Talcahuano, Hualpén, Coronel, Arauco and the coastal settlements of Caleta de Tumbes, Dichato and Tubul. I spoke to academics, urban master planners, municipal planners and local residents. I spent three days in Santiago and visited Viña del Mar and Valparaiso and spoke to Study area around Concepción planners and functionaries in the Ministry of Transport and Ministry of Housing and Urbanism. The trip was part of a follow-on project funded by the Engineering and Physical Sciences Research Council (EPSRC) the main aim of which was to explore the potential for operationalising a method of using satellite imagery analysis to track recovery after major natural disasters. Aims The field trip had two main aims: 1 To better understand the process of reconstruction in Chile. 2 To see if the ReBuilDD method of using satellite imagery to monitor and evaluate reconstruction would be or would have been useful in Chile. This enquiry was guided by three basic questions: 3 How is reconstruction measured and monitored at the moment? 4 Do you think imagery analysis has a part to play? 5 Which indicators and information would be useful? Field Trip to Chile, September 2011 1 THE MAULE EARTHQUAKE The Maule Chile earthquake of 8.8Mw occurred at dawn (3:34am) on the 27 February 2010 at a depth of 35 km (USGS). The event was centred 200 miles southwest of Santiago with a rupture zone of 500-600 km. The earthquake triggered a tsunami whose waves hit the Chilean coast and caused severe damage to many coastal settlements. (Lubkowski et al, 2010) The earthquake affected more than 2 million people, but despite the magnitude of the event, there were few major structural collapses and a relatively low death toll of 500-600. (USGS, 2011) The standard of construction in Chile is generally good. (Booth, 1988) The earthquake is believed to be the fifth most powerful since seismic measurements began. A comparison of GPS locations from before the event to those 10 days later revealed that Santiago moved about 30cm to the southwest. It even knocked Earth a little USGS Intensity Map Earthquake 27/2/10 off its axis. Nasa calculated the tremors moved the Earth’s axis about 8cm and shortened the length of the day by about one-millionth of a second. (Daily Mail, 2010) Of the 7,250 highway bridges in Chile just over 200 were damaged and 18 collapsed. (US Dept Transportation, 2011) Chile offers important lessons in disaster resilience and

The computational area is divided into two computational domains with a grid of 2 arc min and 0.5 arc min. Bathymetry data for the domains are interpolated from the General Bathymetry Chart of the Ocean (GEBCO) 30 arc-seconds grid data. Results from uniform and non-uniform slip models are compared with available tide gauges and Deep-ocean Assessment and Reporting of Tsunami (DART) buoy records.

    CIUDADES, PUEBLOS, ALDEAS Y CASERÍOS 2019 INSTITUTO NACIONAL DE ESTADÍSTICAS Marzo / 2019 PRESENTACIÓN El Instituto Nacional de Estadísticas (INE) da a conocer en esta publicación la edición actualizada de “Ciudades, pueblos, aldeas y caseríos”, tomando como base la información del Censo de Población y de Vivienda, realizado el 19 de abril de 2017. Consciente de la importancia de la planificación regional, provincial y comunal, el INE aporta en este documento datos pertinentes sobre las ciudades, pueblos, aldeas, caseríos, seleccionando las variables esenciales que caracterizan su población y vivienda. Así, este texto entrega cifras actualizadas, datos de población desagregados por sexo, recuentos sobre viviendas particulares, superficie de ciudades y pueblos del país y recientes modificaciones. Esta publicación marca, además, un hito en las definiciones geográficas del INE, ya que en ella se presenta la nueva conceptualización de ciudad, en la que se consideran las características político- administrativas de la categorización. Los antecedentes aquí desplegados quedan a disposición de instituciones públicas y privadas, consultoras, estudiantes, profesionales y usuarios en general. 2 CONSIDERACIONES CONCEPTUALES División geográfica censal: El territorio comunal se divide en distritos, los que pueden ser urbanos, rurales o mixtos. A su vez, en el área urbana se reconocen zonas censales y en el área rural, localidades. Las zonas censales se componen de manzanas y las localidades, de entidades, las que también tienen sus propias categorías. Los límites censales los define el INE y se encuentran sostenidos y enmarcados en los límites de la división político-administrativa (DPA). Sin embargo, su trazado no reviste un carácter legal.
