Article
Solar generation can become a major and global source of clean energy by 2050. Nevertheless, few studies have assessed its resilience to extreme events, and none have used empirical data to characterize the fragility of solar panels. This paper develops fragility functions for rooftop and ground-mounted solar panels calibrated with solar panel stru...

Recent technological innovations have led to an increase in the availability of 3D urban data, such as shadow, noise, solar potential, and earthquake simulations. These spatiotemporal datasets create opportunities for new visualizations to engage experts from different domains to study the dynamic behavior of urban spaces in this under explored dim...

The growing frequencies of extreme weather events and cyberattacks give rise to a novel threat where a malicious cyber actor aims to disrupt stressed components of critical infrastructure systems immediately before, during, or shortly after an extreme weather event. In this paper, we initiate the study of Compound Cyber-Physical Threats and develop...
Technical Report

Compound events such as an earthquake and the COVID-19 pandemic can have disastrous consequences on the healthcare system, leading to overwhelmed hospitals and untreated critical patients. Recent studies have demonstrated a growing need for analytical models to capture hospital system response due to compound events. The healthcare system functiona...

The concept of resilience has been used extensively across the sciences in engineering and the humanities. It is applied to ecology, medicine, economics, and psychology. The novel coronavirus disease (COVID-19) has posed an extraordinary challenge to the resilience of healthcare systems, communities, and nations and has profoundly altered our previ...

The unprecedented growth of solar generation adoption indicates that solar can become a significant source of modern and clean energy for our power grids in just a few decades. Despite solar’s growing criticality for generation, few studies have proposed models to assess solar generation during extreme natural events. In particular, hurricanes brin...

Because solar generation adoption shows unprecedented growth, our power systems may extensively rely on solar generation infrastructure as the primary source of modern and clean energy in just a few decades. Despite this growth, very few studies have captured solar generation infrastructure's behavior during natural disasters to understand their re...
Technical Report

Hurricane Zeta began as a tropical disturbance 300 miles southeast of the Yucatan Peninsula, where it made its first landfall on the island of Cozumel as a Category 1 hurricane, before moving onto the peninsula near Tulum on the evening of 26 October 2020. Weaking overland, as the storm moved back into the Gulf of Mexico, it restrengthened, reachi...
Conference Paper
Full-text available
Hospital systems are an important core of earthquake emergency response because these systems must provide timely treatment to people affected by the disaster. Earthquakes, however, can affect the hospitals' ability to function due to widespread damage to the hospital buildings and their supporting infrastructure. Additionally, earthquakes increase...
Conference Paper
Distributed energy resources (DERs) are expected to increase the resilience of power systems to natural disasters by introducing multiple power-generation and -storage units in close proximity to users. This paper evaluates the increase in post-disaster power accessibility spurred by the rapid adoption of DERs and the potential deployment of microg...

Article
Full-text available
Hospital systems play a critical role in treating injuries during disaster emergency responses. Simultaneously, natural disasters hinder their ability to operate at full capacity. Thus, cities must develop strategies that enable hospitals’ effective disaster operations. Here, we present a methodology to evaluate emergency response based on a model...

This article presents a probabilistic formulation for modeling earthquake rupture processes of mainshocks. A correlated multivariate Bernoulli distribution is used to model rupture occurrence. The model captures time interaction through the use of Brownian passage-time distributions to assess rupture interarrival in multiple sections of the fault,...

Hospital systems play a critical role in treating injuries and preventing additional deaths during disaster emergency response. Natural disasters hinder the ability of hospital systems to operate at full capacity. Therefore, it is important for cities to develop policies and standards that enable hospitals' continuous operations to provide patients...
Thesis
Full-text available
Worldwide, earthquakes have caused tens or even hundreds of thousands of injuries in matter of minutes in countries such as China in 2008 and Turkey in 1999. Because of their suddenness and their long and uncertain recurrence times, large earthquakes pose more critical challenges for emergency response than other natural disasters, for instance, hu...

The formulation represents the elastic-rebound behavior in the tectonic plates and...
Conference Paper
Full-text available
This paper introduces an innovative probabilistic model for assessing earthquake rupture occurrence. This model is able to account for the complexity of time and space interactions of ruptures. The rupture occurrence is modeled as a Multivariate Bernoulli that is updated as a function of the time since the last rupture at different locations of the...

This paper presents the application of a rigorous probabilistic framework that estimates the number, severity, and distribution of casualties over a region. A brief summary of the model is included in this paper. The application is for casualties resulting from a Mw 8.8 earthquake scenario occurring on the subduction fault along the coastline of Li...
Conference Paper
Full-text available
Earthquakes put heavy strains on hospital systems during the disaster emergency response phase. Damage to hospitals and supporting infrastructure disrupts critical hospital functions and damage to the built environment in the hospital's catchment community causes injuries that require medical treatment. As a result, a compromised hospital system ca...

This paper introduces a probabilistic formulation for the estimation of the spatial distribution of multiseverity casualties due to earthquakes. The formulation assesses the number, severity, and distribution of injuries in the affected region. The model is an essential component of resilience formulations of health care systems in a community beca...
Article
Full-text available
Regional seismic risk assessments and quantification of portfolio losses often require simulation of spatially distributed ground motions at multiple intensity measures. For a given earthquake, distributed ground motions are characterized by spatial correlation and correlation between different intensity measures, known as cross-correlation. This s...
Conference Paper
Full-text available
This paper investigates the effects of spatially cross-correlated ground motions on regional loss estimation. Unlike risk assessments at a single site, regional seismic risk analyses must consider spatial correlation that is exhibited in ground motions. In addition, when considering a region with heterogeneous building typologies that use fragility...

Vulnerability functions often rely on data from expert opinion, postearthquake investigations, or analytical simulations. Combining the information can be particularly challenging. In this paper, a Bayesian statistical framework is presented to combining disparate information. The framework is illustrated through application to earthquake mortality...
Article

This study proposes a framework for incorporating time-dependent fragility into large-scale risk assessment models, focusing on incremental building expansion as a significant driver of changes in vulnerability. In rapidly urbanizing areas in developing countries, the pay-as-you-go process of informal building construction and staged expansion is t...
Conference Paper

Hospitals play a paramount role during an earthquake emergency response. Large earthquakes have caused a large number of casualties in many communities in the past to the extent that the hospitals were overcrowded. Therefore, an important information for policy makers and leaders of the emergency response is the estimation of numbers of casualties...
