Summary: The study introduces a stochastic queuing model to evaluate post-earthquake housing recovery, applied to seven regions affected by the 2018 Lombok earthquakes. Results show that the model significantly reduces error in recovery trajectory and better represents the observed overall recovery situation.

Summary: The study explores the post-disaster recovery process in urban areas of Tacloban, the Philippines following Typhoon Haiyan in 2013 using an agent-based model. It finds that slum dwellers recover faster than formal sector households due to quick reconstruction of slums and availability of low-income jobs. One critical factor influencing households' decision to relocate after a disaster is their commuting distance to workplaces.

Summary: This paper explores a new approach to minimize functionality losses of Road Networks (RNs) under earthquake hazards by leveraging post-shock rapid responses. An agent-based modelling (ABM) framework is developed for nuanced examination on resilience of earthquake-damaged RNs. Through a case-study in Luchon, France, post-shock rapid responses are shown to be an effective strategy to increase the recovery rate of RNs' functionality in the aftermath of damaging earthquakes.

Summary: In the post-pandemic era, cities need to undergo transformation in planning and governance, learning lessons from the COVID-19 pandemic to achieve green urban recovery. By accelerating urban mobility transition, achieving regenerative urban development, and creating resilient urban infrastructure, along with defining six pathways supporting transition of urban mobility, energy, food, housing, health, and nature, a roadmap for green recovery in cities can be established that also enhances resilience.

Summary: This paper presents a framework of computer models for simulating the competition for scarce resources during post-earthquake housing recovery, with a case study showcasing the impact on recovery speed and uneven distribution of results. Results demonstrate that accounting for resource scarcity in housing recovery simulations constrains recovery speed, especially negatively affecting tenants and low-income homeowners. Sensitivity analysis of homeowner and contractor firm behaviours highlights their effects on speed and equity in recovery efforts.

Summary: Understanding and mitigating radiation effects are crucial for reliable operation of compound semiconductor based electronics in space and strategic environments. This study employs a multiscale modeling approach to uncover the damage process and explore radiation resistance mechanisms in HgTe. Contrary to common belief, direct amorphization and fast migration of interstitials within amorphous pockets are found to be the dominant driving force for rapid defect recovery, significantly enhancing radiation resistance. This research provides a foundation for predictive capabilities in designing and enabling radiation resistance in robust semiconductors.

Summary: Research indicates that in the recovery process after disasters, multifamily housing and duplex homes recover at a slower rate than single-family houses, further supporting previous conclusions and highlighting the need for disaster recovery assistance programs to target recovery disparities among different residential types in order to ensure a more comprehensive housing recovery.

Summary: This paper introduces a framework to link the seismic performance of buildings with community resilience, and proposes a novel long-term resilience indicator that integrates different magnitude earthquake probabilities. The framework is effective in assessing whether the desired community resilience goals can be achieved by evaluating the seismic performance of buildings and highlights the importance of considering the interdependence between infrastructure systems.

Summary: This paper proposes a Railway operation Recovery method based on Optimal Resilience after earthquakes (RROR) to improve the operation of the high-speed railway (HSR) system after earthquakes. It formulates the optimal scheme for passenger rerouting and train rescheduling, considering the maximum capacity of the HSR infrastructure. The rolling horizon approach (RHA) is introduced as a solution to large-scale RROR.

Summary: Earthquakes pose significant threats to urban communities' built environment. To reduce the catastrophic consequences, it is urgently needed to build seismic resilient cities that can better withstand seismic damage and recover rapidly post-disaster. This paper defines urban seismic resilience, establishes an assessment indicator system, and presents a novel assessment method based on post-earthquake loss and recovery time. The method incorporates engineering systems, non-engineering systems, and secondary disaster risks. A case study in a southern Chinese city demonstrates that it effectively resists possible future earthquake disasters.

Summary: The methodology combines synthetic minority oversampling technique with the least absolute shrinkage and selection operator to analyze survey data and identify business characteristics correlated with recovery within selected time windows. It addresses challenges of imbalanced data and collinear predictors, demonstrating strong correlation between physical damage and business recovery within 30 days. Industry sector, size, disaster preparedness, and disaster financing become statistically significant factors when recovery over longer periods is considered.

Summary: This study considers the impact of place attachment on post-disaster housing recovery and develops a framework to integrate place attachment into housing recovery simulations. The study finds that households with low place attachment, high cost, and slow recovery are more likely to permanently move away from their communities. Low-income households, renters, and those in older buildings are more likely to have low place attachment and experience costly and slow recovery.

Summary: Assistance from HUD is important for supporting postdisaster recovery in states with unmet housing needs in the United States. However, the simplified approach used by HUD to estimate unmet needs is believed to underestimate state needs. This article proposes a more accurate methodology that relies on data obtained shortly after a disaster and can be used for multiple states and hazard types.

Summary: This paper presents a framework to consider the impact of physical damage to infrastructure and household disaster preparedness on potable water needs after earthquakes, using a case study of the water supply system in San Francisco. Accounting for household preparedness helps identify areas where water supply is interrupted, with many individuals lacking personal resources to access alternative sources. Considering both infrastructure disruption and household characteristics can inform decision-making for allocating emergency water resources in the city.
