Introduction
Researcher and project manager at National Research Center for Integrated Natural Disaster Management (CIGIDEN). Sebastián completed his studies as civil engineer and received his master degree from the Pontificia Universidad Católica de Chile. His topics of interest are scientific programming, numerical methods and applied mathematics. He has participated in several projects from bio mechanical engineering to seismic risk analysis. Currently he is working in agent-based evacuation models, seismic risk analysis for water and transportation networks, and the development of a web platform for vulnerability assessment of critical infrastructure under natural hazards.

The occurrence of mega-tsunamis over the last couple of decades has greatly increased the efforts of the research community and practitioners to work hand in hand to reduce risks from these highly destructive threats. Protecting the population through evacuation is the best alternative for avoiding loss of life in the wake of the occurrence of a ts...
The occurrence of mega tsunamis over the last couple of decades has greatly increased the attention of the research community and practitioners to work hand in hand to reduce risks from these highly destructive threats. Protecting the population through evacuation is the best alternative for avoiding loss of life in the wake of the occurrence of a...
Since the 1985 M 8.0 central Chile earthquake, national strong-motion seismic networks have recorded ten megathrust earthquakes with magnitudes greater than M 7.5 at the convergent margin, defined by the contact between the Nazca and South American plates. The analysis of these earthquake records have led to improved hazard analyses and design code...
Natural hazards may cause significant disruptions to road infrastructure, subsequently affecting road agencies, users, and productive activities. Despite the existence of infrastructure fragilities to seismic hazard and some operational consequences on network mobility, previous research has not modeled risk in terms of traffic disruptions and cons...
Electric Power Networks (EPNs) play a fundamental role in the wellbeing of modern societies and recovery of societal functions after an earthquake. Risk and resilience analyses may identify useful network characteristics to improve EPN response and recovery during and after a severe seismic event. This work computes different functional measures in...
The global growth of urbanization has caused an increase of wildfires that devastate communities at wildland-urban interfaces. Agent-based evacuation simulation can be a powerful tool for emergency decision-makers to estimate evacuation times during rapidly propagating wildfires. However, as these models increase in size and complexity for urban ar...
Water distribution is of critical importance under regular conditions, and more so in times of an emergency induced by a large natural event, which also stresses the performance of other lifelines and critical infrastructure. Being able to compare the network operation in normal conditions with, that during an extreme event, is useful for decision...
In the case of near-field tsunami emergencies, evacuation is considered the most important and effective method to save human lives. While significant efforts have been carried out to examine tsunami evacuation within the urban built environment, challenges remain on delivering a more detailed examination of the latter’s suitability for this task,...
CIGIDEN ha estudiado en detalle los posibles efectos de terremotos y tsunamis en el borde costero de Chile, haciendo cruces entre variables de intensidad de estas amenazas con las condiciones de evacuación. Los escenarios analizados dan cuenta de la necesidad de avanzar en normativas y estándares que permitan incorporar la evacuación vertical dentr...
Tsunami alerts following severe earthquakes usually affect large geographical regions and require people to evacuate to higher safety zones. However, evacuation routes may be hindered by building debris and vehicles, thus leading to longer evacuation times and an increased risk of loss of life. Herein, we apply an agent-based model to study the eva...
The importance of evacuation plans has been widely proven in recent tsunami events. Several evacuation models have been proposed to develop these plans and estimate city evacuation times. Typically, single extreme earthquake scenarios are used in these estimations; however, the impact of earthquake damage on the evacuation routes is usually neglect...
Introduction and purpose of this study: Colegio Ingles is the largest and oldest school in the city of Iquique, the capital of Chile's northern Tarapaca Region. In accordance with the School Evacuation Plan, a drill was held in 2013 with the entire student body (n = 1600). The majority of the students had experienced the 2014 Pisagua earthquake. Co...
Computational models of the heart have reached a maturity level that render them useful for in-silico studies of arrhythmia and other cardiac diseases. However, the translation to the clinic of cardiac simulations critically depends on demonstrating the accuracy, robustness and reliability of the underlying computational models under the presence o...
Major earthquakes may require people to evacuate immediately from buildings due to other consequential hazards, e.g. fires, landslides, tsunamis, or significant structural damage. During the evacuation, building occupants are exposed to floor accelerations and physical damage of the building, which affects their immediate evacuation response. Howev...
The electrophysiological behavior of excitable biological media has been traditionally modeled using a nonlinear reaction–diffusion equation commonly known as the cable equation. To account for the propagating nature of electrical waves, virtually all cardiac electrophysiology formulations proposed to date consider a linear diffusion flux, a consti...
Models of cardiac mechanics are increasingly used to investigate cardiac physiology. These models are characterized by a high level of complexity, including the particular anisotropic material properties of biological tissue and the actively contracting material. A large number of independent simulation codes have been developed, but a consistent w...
