    “The study reveals that the United States faces $15.8 billion per year in average annualized earthquake losses - an increase of about 7% since the 2023 update, largely driven by rising property values and growth in hazard prone areas. Yet the message is not all caution: modern seismic codes are working, with states like California seeing ~15% reductions in expected losses thanks to improved building practices.
    This update incorporates the 2023 USGS National Seismic Hazard Model, new population and building stock data, and advancements in HAZUS 6.1, offering communities a clearer picture of where risk is rising—and where targeted mitigation, such as retrofitting older unreinforced masonry and non ductile concrete buildings, can deliver substantial benefits.

    Impact Of Floods On Surface Water Quality - A Systematic Review And Comprehensive Assessment

    “Floods, as extreme flow events, are among the costliest and devastating natural hazards. Among the various domains impacted by flooding, environmental degradation, particularly the deterioration of water quality (WQ), is one of the most impacted yet often overlooked. Therefore, it is essential to understand the nature and source of water pollution associated with flooding. This study aims to evaluate and assess multiple studies conducted globally to determine the impact of floods on WQ. A literature review and assessment of 66 studies published between 2007 and 2026 was conducted using the total comprehensiveness score (TCS). To support the scoring process, studies that scored more than 70% of the maximum achievable TCS (15.4) are considered the most detailed and comprehensive in addressing the objectives of this review. 16 studies achieved a TCS above 15.4, indicating that a limited number of studies incorporate a broader set of factors in this domain. A higher number of studies were conducted post the year 2021, highlighting both scientific progress and a growing focus on WQ impacts from disasters such as floods, beyond the traditionally emphasized socio-economic loss. Among the shortlisted studies, fluvial floods are the most frequently examined, followed by pluvial floods and coastal floods. During fluvial floods, turbidity increased by up to two orders of magnitude, while nutrient concentrations (TN, TP) typically rose by ∼ 10–30%. In contrast, pluvial floods were characterised by dilution-driven decreases in EC and TDS, with DOX, BOD and COD showing variable responses across flood types. This review evaluates flood impacts on WQ, catchment characteristics, and sources of WQ modification. The findings of the research reveal that not all WQ parameters are responsible for WQ degradation during every flood event. Rather, it is a combination of certain parameters that leads to deteriorated WQ. WQ degradation depends on interacting factors such as flood duration, extent, depth, and flow dynamics. In overall, this study provides an overview of the multiple cascading impacts of floods on WQ, along with a detailed perspective on the set of criteria that should be considered in future research…”

    🚨 FEMA’s Hazus v7.2 Is Here — A Major Upgrade For Disaster Risk Modeling

    [I used to work some with Hazus back in the back, but my career changed path; I still appreciate its strength and unity of purpose (sic) #alldataisspatial]
    H/T @Laban "L.J." Johnson | Founder, LJ Learn & Concordia Initiative | Crisis Support · Leadership Development · Community Resilience | Bridging worlds to help people rise
    “FEMA’s Hazus GIS platform has been updated with a new ArcGIS Pro–based version, bringing faster, more powerful tools for estimating losses from floods, hurricanes, earthquakes, and other natural hazards.
    Key updates in Hazus 7.2 include:
    • Streamlined workflows for flood and hurricane modeling
    • New Earthquake ShakeMap integration using USGS data
    • Expanded and improved results exports and reporting (including geodatabase outputs)
    • Stronger security with known vulnerabilities addressed
    • Performance improvements and optimized installation process
    • [Significantly enhanced and comprehensive summary reports for flood and earthquake are now available for download.]
    • Full integration with ArcGIS Pro (3.4–3.6) for a modern GIS experience
    This release represents a significant step forward in how hazard planners, emergency managers, and GIS professionals analyze and prepare for disaster impacts…”

    The Growing Threat of Flooding on Transportation Infrastructure Across Texas Through 2100
    --
    doi.org/10.1029/2026EF008207 <--shared paper
    --
    H/T @Rakibul Ahasan
    “[The researchers] modeled flood susceptibility across Texas at 30 m resolution and projected how it shifts through 2100. The headline is not just that flood risk grows, but that it moves, into places current planning and regulatory maps are not watching. The July 2025 Kerrville flooding sat squarely inside the kind of inland hazard expansion this model projects.
    KEY TAKEAWAYS:
    ● 95% of new flood exposure by 2100 is inland, away from the coast, shifting the resilience problem into interior river basins that planning has historically deprioritized.
    ● Where [they] benchmarked against FEMA's National Flood Hazard Layer, the model flags substantial hidden risk in rapidly urbanizing peri-urban areas, most notably in Greater Houston.
    ● Climate change alone expands the flood-susceptible footprint by 10–12% by 2100, before any new road or land-use development, so this is a conservative floor, not a ceiling.
    ● Half the state's roads and rail and 80% of its bridges already sit in flood-susceptible zones today.
    ● [They] accounted for both factor-importance and spatial-scale uncertainty, using a Monte Carlo weight-perturbation ensemble and multiscale analysis across nested neighborhoods.
    The practical takeaway: this is a statewide screening layer, not a replacement for site-level hydraulic studies. It shows planners and policymakers where the gap between today's protection and tomorrow's risk is widest, and where unmapped peri-urban growth is walking into exposure that regulatory maps still call safe…”

    #Flooding is a challenge affecting everything from economic security, to drinking water & the pursuit of truth & reconciliation. #Canada must adapt to the urgent risks posed by worsening floods. Luckily, numerous pathways exist for individual #Canadians to engage in #CollectiveActions to protect ourselves & our communities.

    #ClimateChange is shifting how water moves through landscapes both in our #communities & around the globe. #Information & #awareness is key in this world of changing conditions. However, a 2022 #audit of #FloodRisk preparedness in #Ontario reported that public awareness of personal flood risk & #liability is poor across the province.

    Many Canadians are just one bad storm away from an unmitigated watery #disaster. Floods are the most expensive & most frequent type of #NaturalHazard in Canada. An analysis of #insurance solutions for flood risk found that current residential flood risk in Canada is estimated at $2.9 billion per year.

    #NatureBased #CommunityDriven #solutions have huge potential to address gaps in #infrastructure, promote resilience & build #ecological knowledge—often at a much reduced cost than traditional hard solutions like seawalls or embankments.

    #GreenInfrastructure can also be highly effective along #watercourses where, once established, vegetation helps to filter surface #pollutants, stabilize #erosion & prevent surges of water from spilling over.
