Combining remote sensing techniques and field surveys for post-earthquake reconnaissance missions

Copyright © The Author(s) 2023. Remote reconnaissance missions are promising solutions for the assessment of earthquake-induced structural damage and cascading geological hazards. Space-borne remote sensing can complement in-field missions when safety and accessibility concerns limit post-earthquake operations on the ground. However, the implementation of remote sensing techniques in post-disaster missions is limited by the lack of methods that combine different techniques and integrate them with field survey data. This paper presents a new approach for rapid post-earthquake building damage assessment and landslide mapping, based on Synthetic Aperture Radar (SAR) data. The proposed texture-based building damage classification approach exploits very high resolution post-earthquake SAR data integrated with building survey data. For landslide mapping, a backscatter intensity-based landslide detection approach, which also includes the separation between landslides and flooded areas, is combined with optical-based manual inventories. The approach was implemented during the joint Structural Extreme Event Reconnaissance, GeoHazards International and Earthquake Engineering Field Investigation Team mission that followed the 2021 Haiti Earthquake and Tropical Cyclone Grace.VM was supported by the Dutch Research Council (NWO), project OCENW.XS5.114.

Disaster Capitalism: Empirical Evidence from Latin America and the Caribbean

Natural disasters are uniquely transformative events. They can drastically transform physical terrain and the lives of those unfortunate enough to be caught in their wrath. However, natural disasters also provide an opportunity to reflect on past failures and, at times, a clean slate to correct those shortcomings. This project takes a political economic approach and recognizes natural disasters as occasions for agenda-setting on behalf of transnational commercial enterprises and market-oriented policy elites. These reformers often use the post-disaster policy space to articulate long-term development strategies based on market fundamentalism, and, more importantly, advance a set of policies consistent with their particular interests. This dissertation delves into that process and identifies the actors, their preferences and the policy outcomes. Using the business conflict model alongside changing transnational processes, this project identifies and traces post-disaster policy making in the Caribbean Basin. It also explores and provides a more nuanced explanation of its effect upon and within certain socioeconomic groups. What becomes apparent is that natural disasters are opportunities to first fracture national economies and then integrate them into transnational processes of capital accumulation. Given that economic viability is increasingly determined by assimilation into the global production processes, reformers in both developed and developing countries use disasters as occasions for re-orienting national economies towards this end. It is within this distorted integrative process that disaster capitalism is located

Social Media Influencers- A Review of Operations Management Literature

This literature review provides a comprehensive survey of research on Social Media Influencers (SMIs) across the fields of SMIs in marketing, seeding strategies, influence maximization and applications of SMIs in society. Specifically, we focus on examining the methods employed by researchers to reach their conclusions. Through our analysis, we identify opportunities for future research that align with emerging areas and unexplored territories related to theory, context, and methodology. This approach offers a fresh perspective on existing research, paving the way for more effective and impactful studies in the future. Additionally, gaining a deeper understanding of the underlying principles and methodologies of these concepts enables more informed decision-making when implementing these strategie

Enabling smart city resilience: post-disaster response and structural health monitoring

The concept of Smart Cities has been introduced to categorize a vast area of activities to enhance the quality of life of citizens. A central feature of these activities is the pervasive use of Information and Communication Technologies (ICT), helping cities to make better use of limited resources. Indeed, the ASCE Vision for Civil Engineering in 2025 (ASCE 2007) portends a future in which engineers will rely on and leverage real-time access to a living database, sensors, diagnostic tools, and other advanced technologies to ensure that informed decisions are made. However, these advances in technology take place against a backdrop of the deterioration of infrastructure, in addition to natural and human-made disasters. Moreover, recent events constantly remind us of the tremendous devastation that natural and human-made disasters can wreak on society. As such, emergency response procedures and resilience are among the crucial dimensions of any Smart City plan. The U.S. Department of Homeland Security (DHS) has recently launched plans to invest $50 million to develop cutting-edge emergency response technologies for Smart Cities. Furthermore, after significant disasters have taken place, it is imperative that emergency facilities and evacuation routes, including bridges and highways, be assessed for safety. The objective of this research is to provide a new framework that uses commercial off-the-shelf (COTS) devices such as smartphones, digital cameras, and unmanned aerial vehicles to enhance the functionality of Smart Cities, especially with respect to emergency response and civil infrastructure monitoring/assessment. To achieve this objective, this research focuses on post-disaster victim localization and assessment, first responder tracking and event localization, and vision-based structural monitoring/assessment, including the use of unmanned aerial vehicles (UAVs). This research constitutes a significant step toward the realization of Smart City Resilience
