An Introduction to Landslides and Mass Wasting

This course is designed to be an introduction to the subject of landslides or mass wasting. Landslides or mass wasting occur in both solid bedrock and in poorly-consolidated sediments. Concerning the latter, loose sands, clays and soft shales can prove to be quite problematic. These type of strata are highlighted in our discussions. We will start with a basic review of soil mechanics and strength of materials, as a precursor to our coverage of the topic of landslides.

Adapting Wildfire Management to 21st Century Conditions

Wednesday, May 16, 2018

The combination of frequent droughts, changing climate conditions, and longer fire seasons along with urban development expansion into wildland areas has resulted in more difficult conditions for managing wildfires. Over the last several decades, the size of wildfire burn areas has increased substantially and nine of the 10 years with the largest wildfire burn areas have occurred since 2000. Wildfires are causing more frequent and wider-ranging societal impacts, especially as residential communities continue to expand into wildland areas.  Since 2000, there have been twelve wildfires in the United States that have each caused damages exceeding a billion dollars; cumulatively these twelve wildfires have caused a total of $44 billion dollars in damages. As of 2010, 44 million homes in the conterminous United States were located within the wildland-urban-interface, an area where urban development either intermingles with or is in the vicinity of large areas of dense wildland vegetation. These challenging conditions present a unique opportunity to adapt existing wildfire policy and management strategies to present and future wildfire scenarios.

Wildfire Management: Recent Trends and Strategies for Adaptation to Wildfire in the U.S.

Interactive map of post-fire debris-flow hazards in the Western United States

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.

Techniques for Developing High Resolution LNAPL Conceptual Site Models

This course is intended for geologists involved in Light Non-Aqueous Phase Liquid (LNAPL) assessment and remediation. This course 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 course presenter is Roger Lamb.

State Responses to Induced Earthquakes

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.

Planning for Coastal Storm and Erosion Hazards

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.

Induced Seismicity in the Mid-Continent

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.

The course presenters are Bill Ellsworth from the U.S. Geological Survey, Austin Holland from the Oklahoma Geological Survey, and Rex Buchanan from the Kansas Geological Survey.
