Consistently computed ground motion intensity measures for liquefaction triggering assessment

The state of practice for assessing soil liquefaction relies on manifestation models developed from databases of liquefaction field case histories. A key component of these case histories is the seismic demand that led to soil liquefaction triggering or the absence thereof. Traditionally, this seismic demand is represented by the peak ground acceleration (PGA), supplemented with the earthquake magnitude (M). The PGA values have generally been estimated using various methods. For instance, some PGAs were considered equal to the recorded PGA at a nearby seismic station, or estimated using ground motion models, 1D site response analyses, or judgment. This data release consists of PGA values at case history sites in the Next Generation Liquefaction (NGL) database, computed using a consistent approach based on Kriging interpolation and spatial correlation models developed using Bayesian inference. Values for three additional ground motion intensity measures (IMs) are also computed: peak ground velocity (PGV), cumulative absolute velocity (CAV), and Arias Intensity (AI). This data release replicates the ground motion IMs available in the NGL database (http://nextgenerationliquefaction.org). The developed spatial correlation models and recorded ground motion IMs used in this study are also included. This release aims at making these data available to a broader audience of researchers.

State Hazard Mitigation Plans and Social Vulnerability

The Faces of Disaster
Social vulnerability spotlighted in 2024 NHERI DesignSafe Dataset Award winner

U.S. state, territorial, and tribal government officials develop State Hazard Mitigation Plans (SHMPs) to assist in reducing the risk of disaster impacts on people, physical infrastructure, and the natural environment. The Federal Emergency Management Agency (FEMA) approves SHMPs every five years as a requirement to be eligible to receive funding for FEMA disaster relief grants and disaster mitigation projects. As of April 2023, FEMA updated policy guidance for SHMPs is in effect that calls for greater community engagement in the planning process and stipulates that plans consider equity and climate change. In response to these changes and research in this area, this project takes the position that more robust conceptualizations and inclusive use of social vulnerability data can help states in the development of multi-hazard risk assessments. Social vulnerability emerges from systemic inequities, resulting in populations facing disproportionate impacts in disasters. It is a helpful framework for identifying underserved and marginalized populations. Given the crucial importance of considering social vulnerability in mitigation planning, our research team built a novel dataset with descriptive data of the populations, definitions, and different measures of social vulnerability included in SHMPs for all 50 states and 5 inhabited U.S. territories. This project includes: (1) the State Hazard Mitigation Plan data; (2) a data dictionary with description of each variable output; and (3) variable definitions for the population groups included in State Hazard Mitigation Plans. This dataset allows for quantitative analysis of the inclusion (or exclusion) of vulnerable populations in SHMPs. Additionally, this dataset can help State Hazard Mitigation Officers and their partners identify gaps in addressing social vulnerability as they update the SHMPs for the areas they serve. These resources are available to all who are interested in addressing social vulnerability in hazard mitigation planning, either through research or in practice.

Seaside Testbed Data Inventory for Infrastructure, Population, and Earthquake-Tsunami Hazard

Community Resilience from Earthquakes and Tsunamis
Built, natural, and social environmental dataset wins 2023 DesignSafe Dataset award

This dataset associated with a multi-hazard testbed for infrastructure resilience in Seaside, Oregon developed for the NIST Community Resilience Center of Excellence. Seaside is located along the Oregon coast and is subject to both seismic and tsunami hazards associated with the Cascadia Subduction Zone. The size of Seaside lends itself to parcel-level analyses of multi-infrastructure damage, loss, and recovery modeling. Datasets are provided for built-, natural-, and social-systems in Seaside. The built environment consists of buildings, electric power, transportation, and water infrastructures. The natural environment (hazards) are the result of a probabilistic seismic-tsunami hazards analysis and the social systems consist of results from a housing unit allocation. Researchers, decision makers, and planners, among others, can utilize these datasets to conduct community-scale multi-hazard risk assessment, focusing on application to the coastal urban city of Seaside, Oregon.

ARkStorm 2.0: Atmospheric Simulations Depicting Extreme Storm Scenarios Capable of Producing a California Megaflood

California Flooding from the ARkStorm
Climate-induced storm flood data wins 2023 DesignSafe Dataset awards

ARkStorm 2.0 is a cross-disciplinary flood emergency management and climate adaptation scenario aimed at quantifying the "plausible worst case" flood scenarios in California in a warming climate. It builds upon the previous ARkStorm 1.0 simulation exercise by incorporating the influence of climate change and by using a systematic, physically-based approach to scenario event selection. The data included include initial condition, forcing, and configuration files for the Weather Research and Forecasting Model (WRF) simulations used to develop the hypothetical extreme storms. It also includes WRF output files containing various meteorological variables (including, but not limited to, precipitation, wind, snow water equivalent, and surface runoff) that may be of interest in characterizing natural hazard impacts. These data are intended to be used in the development of meteorological scenarios, hydrologic simulations, risk assessments, and other activities aimed at quantifying and mitigating natural hazard risk in California stemming from extreme winter storms in a warming climate.

Experimentally Validated Stochastic Numerical Framework to Generate Multi-Dimensional Fragilities for Hurricane Resilience Enhancement of Transmission Systems

The dataset evaluates a scaled aeroelastic model of a self-supported steel-lattice transmission tower and a multi-span transmission line system subjected to simulated hurricane winds. The aeroelastic tests were conducted at the NSF Wall of Wind Experimental Facility at the Florida International University. Their dataset contains three experiments on different models that include a single tower without insulators, three towers with conductors, and three towers with ruptured conductors.

Experimental Investigation of Wave, Surge, and Tsunami Transformation over Natural Shorelines

The dataset examines the potential of mangroves to attenuate wave heights and reduce loads on sheltered structures through a prototype-scale physical model. The tests were performed at the NHERI Experimental Facility at Oregon State University. Their experiment considers six different model layouts that consider the effectiveness of combining three levels of mangrove density with the presence or absence of a structural barrier.

StEER - Hurricane Michael

Learning from Hurricane Michael
StEER post-event reconnaissance helps assess building response to historic storm

On October, 10 2018, Hurricane Michael made landfall just south of Panama City, FL. The natural hazards engineering community swiftly deployed a Field Assessment Structural Team (FAST) through StEER and a complementary reconnaissance team through the RAPID EF. The StEER team broadly assessed the performance of a representative subset of structural typologies in coastal and inland areas, while the RAPID collected using a variety of technologies including unmanned aerial vehicles, laser scanners and applied streetview.

Hurricane Matthew Storm Surge and Wave Simulations with Data Assimilation

On the Level with Hurricane Matthew
Data assimilation using DesignSafe-CI portal improves coastal water level models of storm surge

This dataset includes model simulations and data analyses in support of a study developing and testing a new data assimilation technique to improve coastal water level model accuracy. The study used three different sources for the model's wind and pressure (meteorological) inputs to force the ADCIRC+SWAN coupled ocean circulation and wave model for simulations of Hurricane Matthew (2016). Results showed that the data assimilation method substantially reduced model error by correcting for gradual errors in water levels. These data can be used for study of model hindcast performance, work on data assimilation methodology, or model sensitivity to meteorological inputs.
