The Missouri Department of Natural Resources provides an interactive map of industrial mineral mines (stone, aggregates, and clay) in the state. By clicking on individual sites or areas, users can find a variety of information, including:
Pyrite and pyrrhotite are minerals known as iron sulfides. When iron sulfides are exposed to water and oxygen, a series of chemical reactions breaks down the iron sulfides and forms new minerals called sulfates. These sulfates take up more space than the original iron sulfides. As they grow, the new sulfate minerals push against the surrounding rock, causing it to swell and crack. This causes damage in two main ways:
Coastal hazards are a widespread challenge that cost millions (and sometimes billions) of dollars in the U.S. every year due to property loss and spending on mitigation measures. Based on the most recent U.S. Census, over 39% of the U.S. population lives in areas that may undergo significant coastal flooding during a 100-year flood event1. Additionally, six of the ten most expensive weather-related disasters in U.S. history have been caused by coastal storms1,2. Reducing risk and responding to coastal hazards is an ongoing challenge that relies on close coordination and cooperation between geoscientists, coastal planners, emergency managers, and communities at all levels.
An introductory talk and three case studies from around the U.S. cover coastal storm and erosion hazards in the U.S., as well as examples of coastal hazard planning from the Pacific, Gulf, and Atlantic coasts, with a focus on how geoscience informs planning at all levels. Speakers from California, Texas, and Georgia discuss the impacts of coastal storms and erosion, tools used for coastal hazard mitigation planning in their regions, and examples of community engagement and coordination.
