The U.S. Geological Survey conducts post-fire debris-flow hazard assessments for many major fires across the Western United States. The information from these assessments is provided in an interactive map, allowing users to view fires by location or name and access detailed maps of debris-flow probability in the area affected by each fire. Users can select fires by year back to 2013.
This course is intended for geologists involved in Light Non-Aqueous Phase Liquid (LNAPL) assessment and remediation. Roger Lamb, the course presenter, provides information on the development of high resolution conceptual site models that can be used to guarantee the project goals are met. The class will cover advantages of a high resolution LNAPL Conceptual Site Model (LCSM); design and implementation of a high resolution investigation field program; case studies and end uses of a high resolution LCSM.
The surge in recent years of earthquake activity associated with some oil and gas operations, most notably in Oklahoma, has spurred a range of actions and responses from state geoscientists and regulators. States have taken measures to monitor these earthquakes and moderate the activities that may be causing them, particularly the deep underground injection of large volumes of wastewater. Many states with extensive oil and gas operations but little or no increased earthquake activity have also adopted practices to prevent and prepare for potential induced earthquakes in their area.
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 event. Additionally, six of the ten most expensive weather-related disasters in U.S. history have been caused by coastal storms.
This course provides information about induced seismic activity in the United States, specifically in the mid-continent. It includes information on mitigation planning, the state of seismic monitoring at the state level, and the challenges in communicating the science of the issue to the public and decision-makers.
This course will focus on how to use Membrane Interface Probe sensor results in combination with soil and groundwater analytical results to map the distribution of volatile organic chemical non aqueous phase liquids. Roger Lamb, covers guidelines for using direct sensing tools such as the MIHPT system, best practices for collecting and analyzing soil and groundwater samples, and gives examples from case studies on how to combine direct sensing data with analytical results to estimate NAPL distribution.
Geoscience research is at the forefront of characterizing the earthquake risks associated with the Cascadia subduction zone in the Pacific Northwest. This course covers the science and its implications for policy decisions and resiliency efforts.
Flooding is a perennial hazard for rivers and coasts alike. Every year, flooding results in billions of dollars of damage and the loss of dozens to hundreds of lives across the United States. Efforts to mitigate this hazard rely on the work of geoscientists, planners, and communicators to assess and minimize risks, prepare and inform communities, and ensure that lives and livelihoods are prioritized before, during, and after flood events.
