Summary: Risk and resilience assessments are commonly used separately to guide policymakers in disaster-risk reduction policies, however, an integrated approach accounting for both seems to be lacking in current research due to the challenge of integrating their distinct measurement metrics. Risk assessment estimates disaster risk in terms of operational metrics such as monetary or casualties' loss, while most resilience analysis represents community resilience as an index without specific unit metric.

Summary: The North East India is highly seismically active and classified as zone V in the Seismic zonation map of India. However, there are significant variations in seismic activity and hazard values across the region. This study aims to deaggregate seismic hazard in order to identify controlling seismic sources in the North East.

Summary: This study analyzed cropland changes in a typical agro-pastoral transition zone in northwestern China, revealing fluctuations in cropland areas due to regional climate, natural disasters, agriculture activities, and socio-economic development. Despite worsening conditions, three major coping strategies helped maintain and develop the local socio-agriculture system.

Summary: This study compares the damage caused by tsunamis to monoculture and mixed coastal forests, as well as the impact of different tree planting patterns. The findings show that mixed coastal forests are more resilient to tsunamis compared to monoculture forests, and that forests with a complex spatial structure are more resistant than forests with a simple structure. The functional complementarity of mixed coastal forests contributes to enhanced tree growth and stability, reducing their vulnerability to tsunami impacts.

Summary: This study examines the social vulnerability of the Gwadar District in Pakistan to earthquake-tsunami hazards, showing disparities in vulnerability among villages and reflecting variations in vulnerability at local to regional scales. The research findings can assist emergency managers in identifying community sub-groups that are more susceptible to disaster risks and in developing tailored risk reduction strategies.

Summary: Research shows that earthquakes occurring in the Ryukyu Trench, Nankai Trough, and Japan Trench can trigger tsunamis, affecting Hangzhou Bay in China, especially the prolonged oscillations caused by the 2011 Tohoku tsunami. Spectral and modal analyses revealed that resonant oscillations with longer periods had the highest energy amplification, providing important implications for tsunami hazard assessments in coastal communities.

Summary: The amount of disaster waste is a key indicator of community resilience, which can have negative impacts on the environment. Effective waste management should be implemented in Japan before the Nankai Trough earthquake. Utilizing Monte Carlo simulation and hazard fragility curves can help estimate the risk of disaster waste.

Summary: Subduction zones are responsible for some of the most devastating geological events on Earth, including large earthquakes, tsunamis, and volcanic eruptions. The Cascadia subduction zone has experienced these hazards in the past and is predicted to do so in the future. Therefore, it is crucial to have a detailed scientific understanding of the geological forces and processes involved in order to mitigate risks and protect the growing population and infrastructure in the region.

Summary: In response to the shortcomings of the Chinese code GB/T 38591-2020, a seismic resilience assessment system for reticulated shell structures considering multiple uncertainties is established. The study introduces the square-root-sum-of-squares (SRSS) method and proposes a seismic risk assessment method based on seismic resilience. Through examples and testing, the study demonstrates the effectiveness of the seismic resilience assessment system in considering multiple uncertainties and highlights the potential risk of underestimating seismic risk if uncertainties are not fully considered.

Summary: Seismic resilience assessment is important for evaluating the recovery of structures after earthquakes. However, the current assessment methods often overlook the impact of aftershocks, which can significantly increase functionality loss and recovery time. This study proposes a method to quantify the resilience of structures under mainshocks and multiple aftershocks, taking into account the effects of aftershocks and infill walls. The results show that multiple aftershocks increase economic loss and the exclusion of infill walls leads to biased resilience assessment results.

Summary: This study presents a deaggregation appraisal for 15 significant cities in Western Mexico, considering different oscillation periods, soil conditions, and return periods. The results show that nearby seismic sources contribute most to the seismic hazard for most cities, especially at lower periods. However, for cities far from the Middle America Trench, distant large-magnitude earthquakes contribute more to the seismic hazard, especially at larger spectral periods. Additionally, the study finds that soil conditions have little influence on the deaggregation results.

Summary: A spatially explicit decision support framework was developed using Bayesian networks to quantify parcel- and community-level resilience against natural hazards. Applying this framework to Seaside, Oregon, the study showed overall low resilience for a 1,000-yr event under status quo conditions, improvement of resilience with mitigation options, and the least resilience to mid-magnitude events.

Summary: This paper presents a new coupled urban change and hazard consequence model that considers population growth, a changing built environment, natural hazard mitigation planning, and future acute hazards. The model is applied to Seaside, Oregon, and shows that the most effective policies are those that incorporate elements of both urban planning and enforced building codes.

Summary: This paper presents a methodology to evaluate the life safety risk of coastal communities vulnerable to seismic and tsunami hazards by incorporating the effects of earthquake-induced damage to buildings and debris on evacuation time. The study focuses on the city of Seaside, Oregon, and uses fragility analysis to estimate seismic damage and resulting debris. The results indicate a significant increase in fatality and life safety risk when building egress and earthquake-induced debris are considered, and implementing mitigation strategies can reduce fatalities by 90%.

Summary: This paper compares the National Structure Inventory with a local tax assessor building inventory in modeling seismic-tsunami hazards. The study focuses on the city of Seaside, Oregon, and finds significant differences in input attributes at the parcel level, but more consistent results when aggregated at larger spatial scales. The National Structure Inventory consistently underestimates structure value and number of stories compared to the tax assessor data, and is more accurate when aggregated at increased spatial scales.
