This file contains 1424 household responses to two scales. First, the demographic scale results for the Solotvyno household survey. The demographic household survey contained the following variables:1) Age; 2)Sex; 3) Family type; 4) Religion; 5) Ethnic Origin; 6) Education; 7) Housing; 8) Annual income (in USD); 9) Years of stay; 10) Housing Type; 11) Living Situation and 12) disability.

Second, the results from the Solotvyno Municipality Land Subsidence scale. The first land subsidence risk evaluation sub-scale seeks to answer the following two questions:1) Do you have the following ready in case the land subsides? Please check to each item either 'yes','unsure' or 'no.' and 2) Please rate the difficulty of preparing for each item, by your household, on a five-point scale ranging from 'not difficult at all' to 'extremely difficult.' The second land subsidence sub-scale seeks to answer the following two questions: 1) Please indicate the extent of disaster risk preparedness by your household to each item, by checking either 'yes', 'unsure' or 'no.' 2) Please rate the difficulty of preparing for each item, by your household, on a five-point scale ranging from 'not difficult at all' to 'extremely difficult.'

The BGS Property Subsidence Assessment (PSA) dataset provides insurers and homeowners access to a better understanding of the shrink-swell hazard at both the individual property and/or postcode level for England and Wales. It builds upon the GeoSure shrink-swell data by mapping the hazard to the individual building polygon and considering the other susceptibility factors of building type, foundation depth, and drainage and tree proximity. The user receives GIS building polygons with an overall susceptibility to subsidence score between 1-100. Scores are also classified from non-plastic to very high. Each building polygon is also scored from 1-10 for each subsidence factor (geology, foundation, drainage, building type, building storey and tree proximity). Postcode data is also available as a table showing the ‘average’ PSA score for all buildings within the postcode. The identification of shrink-swell related subsidence prone areas, alongside the inclusion of potential sources to exacerbate this phenomena, can better inform insurers and homeowners and form the basis to make decisions concerning prevention and remediation. The product enhances geological information obtained from GIP and GeoSure via the inclusion of the crucial shrink-swell susceptibility factors (proximity to trees and foundation depth). This therefore allows the derivation of a risk element for the housing stock at Building level, which is then generalised to Postcode level.

Vertical land motion (VLM), angular distortion, and building risks for 28 urban cities in the United States. The file also contains supplementary tables 1 to 8.Abstract: Land subsidence is a slow-moving hazard with adverse environmental and socioeconomic consequences worldwide. However, spatially dense subsidence rates to capture granular variations at high spatial density are often lacking, hindering assessment of associated infrastructure risk. We use space geodetic measurements from 2015 to 2021 to create high resolution maps of subsidence rates for 28 most populous US cities. We estimate that at least 20% of the urban area is sinking in all cities, mainly due to groundwater extraction, affecting ~34 million people. Additionally, more than 29,000 buildings are located in high and very high damage risk areas, indicating a greater likelihood of infrastructure damage. These datasets and information are crucial for developing ad hoc policies to adapt urban centers to these complex environmental challenges.

This layer is a spatial representation of an overlay in the Proposed District Plan and indicates where land use will be regulated by various associated rules. It will be used as a guide in the regulatory process of implementing the Proposed District Plan and managing land use, subdivision, the environment and economy. This dataset is subject to changes undertaken through the Resource Management act. Note individual Proposed Plan rules can have different statuses, some may have current legal effect and others will not until the Proposed Plan becomes operative. This data is provided for use in the District Plan only. The Mine Subsidence Risk Area identifies land in Huntly East that is currently at risk of subsidence due to historic underground coal mining activities and the subsequent closure and refilling of the Huntly East underground mine. An assessment has been carried out to confirm the likelihood of ongoing mine subsidence and methane gas migration from mine workings to the ground surface above the Huntly East mine and the South Headings as a result of the closure of the Huntly East Mine and subsequent flooding of the underground mine workings (see Appendix 5(c) of Section 32 report Natural Hazards and Climate Change). This belongs to the series of data relating to Natural Hazards which includes the following groups - coastal erosion, coastal inundation, inland flooding, and land subsidence. This layer belongs to the land subsidence group (this is the only layer in this group).

The global mine subsidence insurance market is experiencing robust growth, driven by increasing mining activities worldwide and stricter regulations concerning environmental protection and liability. The market's expansion is fueled by a rising awareness among mining companies of the potential financial risks associated with subsidence, including damage to property, infrastructure, and the environment. The substantial costs associated with remediation and legal liabilities following subsidence events are compelling insurers to develop more comprehensive and tailored insurance products. This demand is further amplified by the increasing complexity of mining operations, particularly in challenging geological terrains, where the risk of subsidence is magnified. The market is segmented by application (surface and underground mining) and purchase type (personal and collective buying), with significant growth anticipated in both segments. While underground mining currently represents a larger market share due to the higher inherent risks, surface mining insurance is growing rapidly as mining operations expand into more sensitive areas. Collective buying schemes, particularly prevalent among smaller mining operations, offer significant cost advantages while providing crucial risk mitigation. Key players in the market are strategically expanding their product offerings and forging partnerships to capture this growing demand. North America and Europe currently dominate the market share, but Asia-Pacific is projected to witness substantial growth driven by the expansion of mining activities in countries like China and India. The market's growth, however, is tempered by certain restraints. The inherent complexities in assessing and quantifying subsidence risk can make underwriting challenging and potentially lead to higher premiums. Moreover, fluctuations in commodity prices and overall economic conditions can impact the demand for mine subsidence insurance. Despite these challenges, the long-term outlook remains positive, with consistent growth projected throughout the forecast period. The ongoing development of advanced risk assessment technologies, coupled with innovative insurance products, will play a crucial role in shaping the future of this market. Strategic partnerships between insurers and mining companies, aimed at facilitating risk mitigation and early detection of potential subsidence, will be key to sustaining this growth trajectory. The market is poised for further consolidation as larger insurance companies expand their presence and smaller players seek strategic alliances or acquisitions.

This file contains 1424 household responses to two scales. First, the demographic scale results for the Solotvyno household survey. The demographic household survey contained the following variables:1) Age; 2)Sex; 3) Family type; 4) Religion; 5) Ethnic Origin; 6) Education; 7) Housing; 8) Annual income (in USD); 9) Years of stay; 10) Housing Type; 11) Living Situation and 12) disability.

Second, the results from the Solotvyno Municipality Risk Evaluation scale. Risk assessment and ranking is part of WP1 work, however, the task of WP3 is to conduct an evaluation of the risk assessment and incorporate the community values.Based on the community values and the evidence gathered under WP1, the risk rating matrix can be colour-coded to visualise risk rankings and designate the high, medium and low-risk zones. This would enable the Solotvyno community at-a-glance to view which risks require to be prioritised. In addition, there is geo-referenced data collected on the street where the communities reside to map the community exposure to the land subsidence risk.

The physical properties of soil can affect the stability of construction. In particular, soil swelling potential (a term which includes swelling/shrinking) is often overlooked as a natural hazard. Similar to risk assessment for other hazards, assessing risk for soil swelling can be defined as the product of the probability of the hazard and the value of property subjected to the hazard. This research utilizes past engineering and geological assessments of soil swelling potential, along with economic data from the U.S. Census, to assess the risk for soil swelling at the census-block level in Louisiana, a U.S. state with a relatively dense population that is vulnerable to expansive soils. Results suggest that the coastal parts of the state face the highest risk, particularly in the areas of greater population concentrations, but that all developed parts of the state have some risk. The annual historical property loss, per capita property loss, and per building property loss are all concentrated in southeastern Louisiana and extreme southwestern Louisiana, but the concentration of wealth in cities increases the historical property loss in most of the urban areas. Projections of loss by 2050 show a similar pattern, but with increased per building loss in and around a swath of cities across southwestern and south-central Louisiana. These results may assist engineers, architects, and developers as they strive to enhance the resilience of buildings and infrastructure to the multitude of environmental hazards in Louisiana.

The Delta at Risk study is a global, systematic assessment of how delta risk is increasing due to sea-level rise and human drivers of delta land subsidence. Risk is expected to increase greatly due to relative sea-level rise in deltas. Relative sea-level rise (the combination of offshore sea-level rise and coastal land subsidence) will have a large impact on coastal communities due to coastal flooding. Wealthy countries however have a greater social capacity and wealth to mitigate against such hazards but the economic costs is high. The study utilizes decade-to-century economic trend forecasts to estimate the varying impact on delta risk across each delta system. Efforts to address the root causes of land subsidence in the near-term are critical for long-term sustainability.

The GeoSure data sets and reports from the British Geological Survey provide information about potential ground movement or subsidence in a helpful and user-friendly format. The reports can help inform planning decisions and indicate causes of subsidence. The methodology is based on BGS DiGMap (Digital Map) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of the potential for a geological deposit to shrink and swell. Many soils contain clay minerals that absorb water when wet (making them swell), and lose water as they dry (making them shrink). This shrink-swell behaviour is controlled by the type and amount of clay in the soil, and by seasonal changes in the soil moisture content (related to rainfall and local drainage). The rock formations most susceptible to shrink-swell behaviour are found mainly in the south-east of Britain. Clay rocks elsewhere in the country are older and have been hardened by burial deep in the earth and are less able to absorb water. The BGS has carried out detailed geotechnical and mineralogical investigations into rock types known to shrink, and are modelling their properties across the near surface. This research underpins guidance contained in the national GeoSure dataset, and is the basis for our responses to local authorities, companies and members of the public who require specific information on the hazard in their areas. The BGS is undertaking a wide-ranging research programme to investigate this phenomenon by identifying those areas most at risk and developing sustainable management solutions. Complete Great Britain national coverage is available. The storage formats of the data are ESRI and MapInfo but other formats can be supplied.

The purpose of this document is to provide a technical overview of the impact assessment approach and methods used to identify and evaluate strategies for coastal resilience in the Virginia Coastal Resilience Master Plan (CRMP). The impact assessment produces quantitative data that characterizes how Virginia’s people and landscape will be affected by coastal hazards, now and into the future, accounting for sea level rise (SLR). The CRMP includes eight coastal Planning District Commissions and Regional Commissions. The impact assessment incorporates the coastal flood hazard modeling from the Coastal Hazard Framework, data gathering results, and informs risk summarization and resilience project evaluation. While the study area is subject to other flood hazards such as rainfall-driven (pluvial) flooding, riverine flooding, and other geomorphic hazards such as shoreline erosion and subsidence, these processes, while drivers of risk in all, or portions of the study area, were not included in the first iteration of the Virginia CRMP. These limitations are acknowledged and accepted. Future iterations of the CRMP will expand the hazards considered, including evaluation of cascading impacts from joint occurrence of these complicated natural processes.
